So peaceful with the crickets in the background instead of some loud chitty music... finally getting around to showing my 93 YJ Wrangler Renegade 4.0 5spd 4X4 NP231 some love... gifted to me by mom before her passing and has had some questionable mechanics messing with it over the years, so now I have to question every part in it. Thanks for the info. Currently doing rear u-joints and rear output seal and your video helped me nail down which tranfer case I have to get the right seal.
I was a manufacturing engineer at NPG, Your 242J is a full-time unit with an interaxle differential. It was the best we made. Magna moved the operation to Mexico. Gm is going to electric vehicles, they won't need a transfer case.
Learned more about transfer cases and function from this video and your follow-up video than from all other videos I've ever watched. Thanks for that. Subscribed and have watched a half-dozen more!
@@DEInTheGarage I’m going to watch this again a few more times! I’ve already watched it a couple in the past… but now I wanna get down there and see what mine says!
There are so many great videos on Jeep GC's, thats why I love them. Mine is a 2000 WJ 4.7ho with a 247hd. Its a fantastic 4x4 system. This is a great video. thanks mate.
The 4.7 HO motor was standard in 02 to 04 Overlands, and optional in 02 to 04 Limiteds and Special Edition Jeep GC's. Yours being a 00, I doubt it's a HO 4.7 motor. Probably the standard 4.7L.
@@mrmo666 Hello Mr Ho, My engine was changed due to a spun big end bearing. The new engine is a HO as the supplier did not have a standard one. All HO parts are also fitted too.
Thanks for this, I've got a 97 ZJ and when I bought it 10 years ago I didn't understand permanent 4wheel drive. I put 2 new tyres on the front and kept worn tyres on the rear. After about 20 miles it chewed up the front diff. At that time I failed to appreciate the need for even tyre sizes all round.
First off just found your site love your content keep it up I have a 2005 Jeep Wrangler Rubicon unlimited my new process data plate is a 241j I'm wondering if they labeled it incorrectly with the 4 to 1 ratio
245 j is on my 2005 grand cherokee limited hearing clicks and some play diving straight or turning and only happens if my foot is on the gas pedal anything past putting it........Quadra drive 2
The ZJs had the 249 Quadra-Trac transfer case, they had a viscous coupler in the transfer case....the WJs had the 247 transfer case, and they also came out with the Quadra-Drive system which had vari-loc front and rear differentials and the clutch pack in the transfer case, which is what you were referring to around the 11:15 mark. The gerotor coupler was used in the Quadra-Trac/Quadra-Drive transfer cases found in the WJs. The 249 and 247 were never used in the XJ, or MJ. both of those either got the Command Trac 231 or the Selec-Trac 242 transfer cases, or no transfer case if you bought a 2WD Jeep, not sure why anyone would but they are out there.
Thanks bud. Just trying to help some like minded folks. Definitely some grinding oh whirling/humming noise. If it is a limited slip diff you will get binding when turning at low speeds
Thanx for tellin me about the last digit being a 1 is a no no for turns and roads i gotta long bed sierra its a 2000 manual transfer case with a 261 very educational👍
Hooollllld up. Gotta clear something. I know this is old, buuut.. The 247 in the WJ had the gerotor in what they called the progressive coupler, with the clutch plates. Had the special fluid with the "friction modifier" in it. Does not take ATF4, which can wreck it. Used in the QuadraTrac II and QuadraDrive I. The same kind of coupler was in those funny LSD diffs. The 249 in the ZJ had the "viscuous coupler" that was sealed but contained a weird silicone fluid. When it failed it would either lock up entirely or never engage at all. Took ATF4 otherwise, iirc. Could be wrong about that. Feel free to berate me if required!
Nope, you are correct. the 247 is basically Varilok in a transfer case where ase the 249 is an odd non serviceable unit. It has been many moons since I recorded this video, so I cannot remember exactly what was said... did I misrepresent some of that info?
So, correct me if I'm wrong.. I have a jeep Grand Cherokee (WK) 2008/9 (Canadian 10 of 08) 3.0 CRD Overland with an NV245 & as it states on the window sticker.. a "DGU" w5j400 (NAG1) trans, Quadra Trac II "active full-time 4WD system, 4 wheel traction control & 3.73 electronic limited slip differential front & rear axles" It seems that the NV245 is now about the same system as the 249 you were talking about.. I'm looking to you because it appears I killed (loud gear/ grinding noises coming from the center of the car) the NV@$% while towing ~3000 lbs for 2000 miles with new tires on the front and 3-4/32 above wear bars on the rear tires.. Buying a transfer case now.. ELSD's are probably also questionable..
Good job man Thank you good info. What do you know about jeep commander 245j I need to replace the drive chain? Do I need to take the transfer case to neutral? I tried that the light blinks but nothing happens is that the motor drive that does that?
So my new question for you is. Should I swap the front and rear diff from my 01 to the 04 ? Since the ABS system is part of the Quadra-trac system I don’t know if the abs module would need to be swapped as well. Or should I just put the locker in front and rear. Thank you again for your input 🇺🇸
Great video. I have a 1997 grand Cherokee with a 249 it's leaking and not working right. I want to switch to a transfer case that has 2 wheel drive with 4 Hi and 4 low. The only thing that I found is a 242 J but it is in a 2003 liberty. Can I switch it out without changing the input and output shafts I believe they are both 23 spline. Hope you can help me with this problem.
I have a WJ 4,7 with a 247 that burned up due to low fluid, What would you suggest installing? I will take it off road and use it as a daily driver too. LMK Please.... Great Video
Get a 242. It gives you 2wd which is better for driving around town and then you can lock the diffs together for off road. 231 is good as well, but less options
Hi thank you for your video it helped alot .if ok to ask you a few questions .u need a new transfer case for my dodge .and now I was told I need to know if it's a 23 or a 29 spline shaft .and also if the electronic shift box qhen pulled out there is either aa hex nut or a torx nut the the box attaches to .and another video I saw they said it will tell you that with assembly number but I don't understand that part the I'm just concerned as it's a 4 hour drive lol so I don't want to hit there and find it's not usable .and I don't know if they seller understands what I'm asking lol is ther anyway to find that info out qith any of the numbers on the tag by chance ? Please and thank you
The j stands for jeep if it has a D then it's a dodge and ya u guessed it if it has a C it's a Chevrolet and on some of them that letter will be followed up with LD or a HD for yep light or heavy duty haha
That's good information. Thanks for sharing. I am doing an engine swap in my Jeep and will be using an NP241C transfer case. (It matches up to the transmission I will be using.) I bought it as a stand-alone, so I don't know which vehicle it came out of. The serial number has a 95 in it and there is a 96 stamped on the case itself. So, I am assuming it came out of a 96 Chevy something (Tahoe, Silverado, etc.) I am struggling to find some information about it. It has a three-pin 4WD shift indicator switch near the selector. (Most of the ones I have seen have a two-pin.) I need to wire it to my engine wiring harness. Do you have any idea where the three wires should go? Or, do you know where I can get a wiring diagram for it? Thanks
Hello sir. I found your video very informative. I recently purchased an XJ with a 231 and to my knowledge the case came from a different vehicle and I’m watching your video to try and and determine what year vehicle it came from by reading the tag. If you or anyone else that’s reading this can tell me if the serial# has that info or how i can get the manufactured date and if so does that date coicide with the year of the vehicle. Any info would be greatly appreciated. Thank you
@@victorjramirez1948 Fair enough. To my knowledge you cannot tell that simply be viewing the case. If you were to remove the case and count the spline count on the input shaft if might give you some clue as they changed that over the years
@@DEInTheGarage Hey Doug, I know this is an old video but there actually is a date code on the outside of the case. You can determine the casting date of the cover anyway, to the year and month. At :24 in the video you can see two pie-shaped circles to the left of your red and silver tag. These circles are divided into 12 pie slices around a smaller circle. The year of manufacture is in the center of the pie, and each month has a unique slice. On the first day of the month, they drill out a small dot in the month slice, which shows up as a small raised nipple on your casting. When they reach December, sometimes they will just cut another pie grid next to the first one. You can see this in your video. So if your pie thing has a 97 (or just a 7) in the middle, and four pie slices have dots in them, then your t-case cover was cast in April of 1997. You can assume your vehicle was manufactured within a couple months after that date.
Thanks for the video. It helps explain a few things that I needed to know. I also have the 242j. In a 2002 Jeep Liberty sport utility. I'm trying right now to put a chain in. The rear seal is also leaking. Fun fun!
Hey fellas its me again.... 2001 Durango blown trans case... I found a 2004 durango with an RFE Trans like mine but dont know if its a 244d or not...tag says ...TITTJ019421154 19:11:38 then P52119554AA RFE Is this a 244D ? please say yes LOL
The Renegade trailhawk uses a single speed power transfer unit. It has no low range gearing. It has a"low" mode but its just computer software that locks the transmission in 1st gear.
New Process Gear was owned by Chrysler and was sold to a consortium of employees and investors becoming New Venture Gear. The only difference is the tag. It was again sold to Magna Powertrain recently.
Why would anyone down vote this? Dudes providing great info to the uninformed.....like me. Nissan guy, working on wifes 2nd XJ, 1st one never had a problem. Now the current monster is ALIVE. Stuck lug nuts from her taking it to a tire shop, I'm putting new front hubs in to stop "Death Wobble" & just happened to see this. Now to the question. I can get it into 4 wheel H, but NOT 4 wheel L, grinds, growls & I swear it told me to FU*K OFF! I think I read or heard it runs on a vacuum, That sounds crazy to me. What if the "hose" get hits by a rock? Hopefully I get an answer from here. Don't really need 4 WL, but I don't like things not working, yes double negative statement. Subscribed! LIKED! Still pissed about the 2 down votes & it's not even MY video.
HEy man, thanks for the feedback and support. I guess some folks don;t like free information. haha. Your XJ should not be vacuum actuated. Jeep did that in the 70' snad 80's, but I don;t thin the XJ ever got it. Certainly not the 90's ones. To shift into 4LO the transmission needs to be in neutral, so maybe that is your issue? If not, let me ask you what your your Cheorkee is?
@@DEInTheGarage 1992 Jeep Cherokee. Thxs for the quick answer. Heard about the vacuum deal from an old timer, which I'm fast approaching, Almost relieved now. We had 1 before about 15 yrs ago, 89 Jeep Cherokee, for about 4 years. Went into low no problem. I put the current one in N before going to low, ostensible to just see if it worked.......it didn't. Her brother thinks it's low on oil, I think linkage when trannys don't shift right. I think that because the previous owner put a "rebuilt" motor from Autozone in it way back in 2001. Great channel THX!
I have an 01 WJ AND and an 04 Both have a 247J but (01) is Quadradrive , (04) Quadratrak 2 Both are 4.7 but what is the difference and what is in your opinion the best transfer to have it’s my hunting Jeep and I pull a boat often times The 01 seems like the 4/4 works better in the mud. Thanks for the info sounds like you really know your jeeps 👍🇺🇸
Same transfer case (as you suggested) the quadra drive also has front and rear VariLok limited slip differentials which the Quadratrak II has open differentials. You 01 does better in the mud for that reason. as soon as the tires slip a bit, the transfer case and axles lock up for all 4 wheels are turning together. "best transfer case" is open to a lot of factors, but all around I prefer the 242. It has a 2wd option which is better for on-road MPG and towing, but still has part-time and full-time 4wd as well. I am actually in the process swapping the 247 from my 01 Quadradrive with a 242. This configuration of the 242 with the QD Varilok axles is in my opinion the strongest you can have
Thank You for the great video and information. I have a 2001 jeep grand cherokee larado with quadra trac. The transfer case tag reads 247 j . The left front wheel does not pull or spin when all four wheels are of the ground. Any ideas? Again Thank You.
Yes. Quadra Trac uses a limited slip trasfer case, but open diffs. That means - when locked - you are on guaranteed one wheel in the front and one in the rear spinning. Quadra Drive came with limited slip differential as well guaranteeing 4 wheel lockup
Hello. Two question’s please. I have a 97 ZJ with a 249. I understand from other videos earlier NP249’s the axles are not locked but newer NV249’s the axles are locked. How do you tell visually whether you have a NP249 unlocked or an NV249 which locks both axles? And a second question. I was given a NV247, is there any benefit to switch from 249 (not sure if mine is locked or not. Just bought it) to NV247since I have it or should I try and sell both to get a NP242? Thank you so much. New to Jeep’n. BTW great channel and mine says 249 j.
Thanks for the video... I saw it very carefully, but you didn't mention (to describe) the number 0 of the second digit and the number 8 of the third digit. I have a 208 AM transfer case. I am also curious about the meaning of the letters AM. This transfer case it's on a Mexican Wagoneer 1982. Thanks in advance!
Hi there. Tq for yr video. I owned a Jeep Grand Cherokee ZJ 1997. It is now having transmission problem. Leaks and gear doesnt engage. I am from Brunei. My local dealer is not helpful saying the parts I need are discontinued. I have sent you an email seeking your help if you know any reliable supplier frm the US I can order the required parts. Thank you.
Yep, QuadraTrac I is the marketing name they give that particular 4x4 system. There is also QuadraTrac II, QuadraDrive, SelecTrac, RockTrack. etc.. All just names for different transfer case/differential combinations.
Its the same as the Quadra-Trac 2 but lacks neutral and 4Lo, its just a full time 4WD setup. Not sure if it had any sort of coupling to transfer torque between the front and rear or if it was a set torque distribution. Basically the typical Lazy American's AWD.
Great channel thanks for sharing. On My 2000 jeep Cherokee XJ the rear drive shaft broke and I have just been using 4H the front wheel drive for about 6 months now. QUESTION do you think I am getting abnormal wear on the front wheel drive components from doing this compared to normal rear wheel drive 2H?????
Definitely. If you look at your front drive components compared to your rear (drive shaft, axle, etc) they are must smaller as they were not intended to move the vehicle alone. Not saying it wont work, but if possible find a drive shaft. you are going to be really stuck if you break something in the front!
@@DEInTheGarage Thanks for the reply. How are jeeps different then front wheel drive cars. It seems that the front wheel drive system was designed for off road extreme rough use. After watching a few transfer case videos it seems they designed the transfer case to be very robust.
@@DualTasticToday This is true, but you XJ was designed to be rear wheel drive when operating in 2wd, not front wheel drive. The components were not designed to carry the entire vehicle. I am not saying you are destroying the jeep or anything, but you are certainly using it in a way that it was not engineered for and at some point I expect certain front driveline components will wear out prematurely
Hi I have a 2003 jeep Cherokee and need to change transfer box, what numbers need to match when looking for a transfer box online. Any info would be much appreciated. Thanks
Some of the Dodge Durangos had the 242HD transfer case, not very common finding them, but they're out there, I found one a while back in a Durango R/T with the 360 V8, so obviously they're pretty well built to withstand some pretty high torque through them.
My 1994 Jeep Grand Cherokee Laredo v6 4.0, when I turn my rear tires skip so I thought it would be the transfer case ratio249 so I see the 231 ratio won't work on my jeep I believe right?
Yes, but you will probably have to switch the output shafts. I have a video on it. It is long, but it will give you all the info you will need ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-bfVHWCqZcbA.html
My 2001 Durango SLT 4.7 Transfer case exploded....it is a 244D... Can I get a very simple answer to this question...Can I use a 4.7 ,233d to replace it? The 244"s are really hard to find and when you do they want a fortune..($500)....... 233d"s......$50....Will it fit?
Simple answer, yes it will fit, but you will need the input shaft from your original transfer case to get it to mate up to your transmission. That means splitting each case and swapping the input shaft. not a difficult projects
According to your explanation, middle digit represents number of positions. So what's the explanation for the 231 vs the 241OR in rubis? Both have the same number of selector positions and yet one has 3 and the other 4?
No, the first number determine the the number of positions and the middle number is a size or strength number. The 231 and 241 both have 2 gears (high and low), but the 241 is a bigger a beefier option. If you watch from 2:20 to about 4:00 i explain the first two numbers
Technically you can take the year of the vehicle and the transfer case and search the internet to figure out which year with which t-case had which output shaft. There are always going to be outliers because Jeep and that is just the kind of fun games they play. Additionally, it is not just the spline count which must be taking into account. Different applications of different t-cases use different length input shafts.
Hi buddy my jeep wj has a 247j my question is if i have my truck in 2wd or its in 4wd all the time so my display its broken and i just buy the truck thanks for let me know
Do you know if you could swap out a NV150 jeep grand 2005 and put in a NV245 without much hassle? , I know that is the some jeep grands there is a little lever to go into 4low, maybe that would also need to be swapped as well?
Well anything is possible, but that is actually a pretty heavy swap due to the electrical components in the 245. I cannot speak intelligently on the matter though as I have never attempted it or seen it done personally. Here is a JeepForum thread on the topic. I would suggest reaching out to the guy on there who did it as he can probably give you some much more reliable info. www.jeepforum.com/forum/f67/qt-i-nv140-qt-ii-nv245-swap-s-395686/
I have a 244D in my 04 Ram 1500. Would the guys of it be the same as a 244? Any idea what the D is? It has three modes AWD, 4hi, and 4 low. Electronically selected. Gotta do a rebuild and can’t find much info on the 244d.
My understanding is that the 242J and 242D are internally the same. I believe the "J" is for "Jeep" and "D" is for "Dodge". The differences come in on the 242HD which has the same selectable modes as the D and J, but is beefier inside. Your D and my J should be identical inside.
hello, the video is great... do you know how to install a jeep cherokee xj transfer case from a grand cherokee 242hd if anyone knows, please help, thanks in advance
I was just going to ask the same question but decided to look in the comments and I found what I was looking for. Good source of info. I'm subscribed now. Ty
I'm not a fan of the full time 4x4 system...I figure if its slick enough your not getting the traction you need in 2wd then its slick enough you aren't gonna hurt anything being in 4x4. They are known to have the viscous coupler fail at the worst times.
They are the same case, basically, but I believe the spline count on the input shaft will be different, so you would need to use the AMC input shaft in the 231J if you go that route. not a hard thing to swap over
95 xj swapping for a 99 xj both 4.0 both 231 both automatic any differences in those or can u point me in direction to figure it out i would assume its much like chava original question but double check
