MP3023 Transfer Case Repair 

Glad it helped, thanks for watching.

More power, not that I know of. Swap, not that I know of. Updated parts to help with the problems they have. Seals, range fork and sleeve, motor, HD levers, output shaft and snap ring.

It is not just front to rear. Any tire that is different will cause problems. Get people all the time that come in and get pissy with me when I tell them they have to go buy four new tires. They always say I just bought one or two not that long ago, usually it is one, why do I need to buy four. Well, you don't, but you do if you want your problem to go away. Drive it long enough and you will destroy your transfer case. One of the disadvantages of an AWD system. Same thing happens on vehicles with cornering technology like BMW's. At least on those it just won't shift properly. Thanks for watching.

@@CurmudgeonTransmission Many thanks for the swift and comprehensive reply. I now fully appreciate that any tyre size mis-match will cause issues but I still don't understand why? Hope you can help. Cheers.

Because a different size tire has a different rotational speed that the computer translates as slip and tries to compensate for it. In the BMW's case it translates that as you are in a cornering situation when you are not.

@@CurmudgeonTransmission Many thanks, will definitely keep an eye on tyre size.

This unit does not have a part time mode, it is full time 4wd and the clutch is constantly working. It has 4wd auto, neutral and 4wd low. Should never be driven in 4wd low on dry pavement. One of the bad things about full time 4wd and awd vehicles is the tires have to all match. I get people in all the time because they replaced a tire and they started having problems. They get really upset when I tell them they have to now go buy 4 new tires to correct their problem, or before I will even think about working on their vehicle. It does not take long to take out one of these units because of that.

Not yet, sorry.

@Curmudgeon Transmission No problem. Do you know of any sources for rebuilding information? I've tried searching the net and have come up with nothing.

None that I know of. Give me year, make, model, engine size and I will see what i can dig up. If I do find anything you will have to go to my Instagram to share it.

@@CurmudgeonTransmission It's a 2010 Grand Cherokee 5.7. The Tcase is either a np245 or nv245

According to the book I have it's a NP245 or NP146. Go to my Instagram and send me a request.

was using 3 and they were all Snap-on SRP5A, SRP3 and I believe the ones I used at the end were SRP1B.Very hard to get in there because of the 2 holes, they should have made it a slot like all the others.

Tom Bearden Working on exact model but all my pliers are too flat to grab it and yes thinking about cutting those 2 damn circles and turning it into an oval shape like on the New Process transfer cases. Been stuck on the tail housing for 2 hours and almost thru a tube of silicone. Thanks for the info

Tom Bearden btw, where’s your shop located?

@@Dontknowwhattouse Know the feeling, I've been asked that question before and I am not trying to be an ass but I am not giving that info out. I will give out all the knowledge I have but my location is not one of them.

Tom Bearden no problem bud but if you’re in the Houston area and ever need any manual Tranny advice or parts I’ll be glad to help out.
