Oh, and thanks for the Droman steam pipe part numbaA set of four cost $6.95, on the wayAlmost done cleaning and reconditioning pieces parts. Taking a gamble on the starter. May be original, but was working fine, so a good cleaning, some paint and I'll bolt it back on.Was thinking of doing something cool with the plastic cover to tie the new color scheme altogether.
Did we figure out if your T case has the same stupid pump rub issue as duramax? Sent from my iPhone using Tapatalk
Don't think the 2002 non Allison has that issue.Looks like it is a NP246 on the 4L80E.I need that trans kit for my suburban.
Pretty sure the NP246 is half ton JR...?...edit: So I guess they had 246s auto 4wd in 3/4 ton as well, but also the 263s (like dmax) and 261 manual shifters. Don, best to read the tag on the rear of the case to give us something to go on.
Gunna have to crawl under there!!

Ding ding ding! get the pump rub kit and do it while you have everything out. you ARE affected by it. if you have any fluid on the outside of the case you probably already have a leak, and it will be evident by the output shaft seal being dry but still have fluid on the case behind it.
2 notes on doing the pump rub don...1. If i remember correctly. the bolts holding the xcase to the trans i believe are 15mm, and you will need a short stubby wrench for the very top bolt (if you have pulled it all then nevermind.)2. The split ring is a pain in the butt..(both tear down and re-assembly). because they do not give you a lot of room to work with, and the split ring sits in a little groove. Also there is no hole in the split ring to get a hold of it with the pliers.
I decided to use sheet metal screws and screw the tires directly to the rotors to save weight!Should work.

Here is a video on how to do it......i wish i would have had this when i did mine. The lifting/prying up of the gear was something i did not know of.https://m.youtube.com/watch?v=y7im00Wm3sQ
I just don't want to wind up missing a digit or limb. I can sometimes get in a hurry to get results.
I think I did a DIY on it. The split ring there are ‘fancy’ pliers. Read flat wide tips with traction on them. They’re cheap enough but do help with the pesky ring. DONT FORGET THE ABS SENSOR! I got away with it...but was heading for a bigger than bfh and noticed it. It is dirt simple, other than the pesky top bolt as mentioned. Just do it and be done. Easy now while you’re in this far.
Wish Merchant had that video when I did mine -- that screwdriver on the gear trick would have helped a lot. That snapring is a pain. I overstretched mine a little bit, but was able to massage it back to normal.
Wheels look good chief!Tires as well. But they’re a lot of tire. Hope they fit for you.
