GM's NP263HD Transfer Case teardown...is this thing any good?? 

I have chevy Blezer k5 1970.motor 6.0 trass.4L 60 E intll.whit Full injetion my quesitos is .I need trafer case wlht seed sensor for workign my trassmition?????

I just finished rebuilding my NP 261 HD transfer case today. Thank you so much!

That’s an excellent break down and description. Doing some troubleshooting on mine. I can put downward pressure on the output shaft and get a popping noise. I’m guessing that c clip support for the bearing has come free. Have you run across this before? Thanks.

Good tear down.Thanks I had that hole in my 2004 6.0 2500 HD. I am so glad I caught it but having said that you may never know you are losing oil because the hole is above the oil level and it only throws it out when moving. Will not show leak while parked.GM new about that pump rub issue. Merchant Automotive sells a good pump upgrade kit.

I know this is an old vid but does anyone know if the front case half is the same between the 263HD and 263XHD? I’ve got a 263HD and the input bearing is loose in the case (side to side and back and forth).

Picked up the 263XHD chain/sprocket upgrade rebuild kit and upgraded case half for my 263HD from Rigid Axle. Got a pretty good deal on the full rebuild. Thanks for the tear down.

I think that it the worst transfer-case I've ever seen torn down. That was a mess and I don't blame the guy not proceeding with rebuilding it. Again, another great tear down even with losing the audio portion you filled it in just right. Those seals have always kicked my butt just like it did you. I wish there was a better design but it is what it is. Thanks for another great video Smitty and Please keep them coming.

Great video on the tear down; my 03 Chevy 2500HD transfer got a hole in the rear case, dropped all the fluid in the driveway; I was debating about rebuilding it but I may go the route of buying a refurbished. Thanks for the info

Never saw a transfer case disassembly before. Very well done video. I like seeing you struggle with things. We viewers need to see how hard like the seals can be. Too many videos show everything going so smooth which isn't the case. Thanks again.....

This is the best video I have found on the tear down of a 261 HD GM transfer case! Thank you!

@22:49 that front seal can be taken out from the rear on the rear of that shaft there’s a big snap ring you take that off then flip to the outside put wood on the shaft hit with hammer through seal that snap ring you’re talking about under the seal holds the bearing onto the shaft the snap ring inside holds the shaft in the case Once you hammer the shaft out with the bearing easily tap it through the seal flip the case over tap the seal out from the inside Hope this helps with future tear downs

How do the GM transfer cases function in the newer GM 1500 pickup trucks with the "auto four-wheel drive" selectable mode? Do they have a clutch pack inside of them or is it gear to gear hard lockup?

Found near exact issues with the 263 in my dad's truck tonight. I had it diagnosed fairly quickly. I found your video after. It's good to hear that what I found in his is a common failure in these. I wasn't sure how it was caused. Great helpfull video

I've found the easiest way to pull the front seal out is with a slide hammer with a screw.

It's sad how that trans fluid just leaks out with little warning, my old 263 hd case was had to be the same shape if not worse. I Just picked up new 263 hd case with low miles an clean fluid for 500 so I split it apart an installed a case saver an replaced all seals so we're all good now! Nice video & thanks......

Input seal starts at 30:30 and front output seal starts at 22:20 Great vid thanks for posting. Stay gold

Very good and informative video. Keep up the good work. I’m curious as to would it have been more beneficial to use a vice or stand to hold the transfer case stationary to disassemble? I am currently debating on rebuilding my transfer case myself, buying a new/refurbished (don’t know if they sell new or if they are all “new” refurbs) or having a shop just rebuild it. But this definitely helps in favor of doing myself does not look difficult at all, more time consuming than anything making sure to keep track of parts and order of which they go together. Thanks for the video and keep up the good work with videos.

A very good tear down video. Very well done. Love your attitude. Subscribing for sure!!!

Thank you watching your video helped me pull mine np261 apart about the snap ring from inside to pull it apart now I finished it with putting a nfw slip yoke eliminator in now I can have my front drive line cut to fit an my 2001 2500hd 6.6 sas kit done thanks again

Hey good afternoon, what type of brand are those c-clip snap ring pliers and and if possible do you have a model number or part number for those pliers? Thanks in advance

what the difference between hd and xhd physically? so the 263 hd front case half is aluminum and rear is magnesium??

You make it look easy 🤔👍

Hello. Can a bad transfer case make my truck vibrate as i drive and only do it at the speed of between 26 and 32ish? Miles amd hour after that i would smooth out. Please advise Thanks!

This was an interesting video very eye catching.

The very first thing you do when you inspect it, when you pull and push the rear output shaft, what causes that and how is that fixed?

I have a 263hd and I want to swap it to a manual t case ...what manual t case would swap on to the 4l80e ?

What the difference between the 246 and 263 ?

This video has definitely helped but I do have a question. Is the fork pad the only thing that has plastic on it?

I'm having problem getting that first snap ring that holds the rear half on back on after reassembly. Can I just rip it out or is it a necessary thing to have?

good video - why is the camera guy so shaky though?

I'm getting ready to have to pull my case on my 2000 GMC sierra 4wd 1500 does it have that case?

Thanks for the video, what brand of snap ring pliers do you have there? I need a good pair

Well I found this highly informative and it explains why I have problems with my Chevy Avalanche not moving after I moved the 4 wheel shifter and back into 2 wheel drive and it popping out of gear and having to shift back into 4x4 then back to 2 wheel drive just to get it to move

Why are we now not usi

Great job

I just got with a 2001 gmc 2500hd 4x4 non-working four wheel drive the only thing it does is the transfer case shift motor just has buzz noise when pressing the button on the dash and the front shift motor will not engage either. any ideas?

Do you know how to find a 2 1/4 turn high effort steering gear?

Thank you so much for the video..i learned a lot..do you have a 4l80e one?
