Transfer Case replacement

I just found out that my transfer case has a whole in the bottom and It is binding up. Feels like something is getting caught between gears and bottom line is needs replace.

My question is how difficult is it to replace. I am mechanically savvy but have never pulled one of these apart. I would be doing this on the ground on my back. Shop wants 2400 to do the repair. Thoughts? suggestions?

I did my tcase fix myself, I'm a welder so that helps. it's a magnesium case so welding know how is critical, your cheapest bet would be to remove the tcase, just use a floor jack. open it up, remove housing where hole is, give it to a good welder, be sure to tell him it's magnesium. then inspect the tcase for worn/damaged parts and replace as necessary. when I first detected the hole I removed right away and repaired the hole, cost me about 100bucks in parts, gm has a updated clip for the pump, I wouldn't bother with the aftermarket, pump plate assy's (kennedy diesel, etc.) They are not necessary IMO, the gear guy I deal with says after the tcases get the updated 8 dollar clip, he never see's them again. I will refer you to my gear suplier : Border Parts, 3875 Bancroft Drive Spring Valley, CA 91977 (619) 461-0171 the guy is a whizz. At very least I would remove and open to assess the damage. Good luck.

We have an 01 with the 8.1L. Transfer case had a hole in it when we got it so we got the updated clip from GM put in and a new half put on. Guess what it has another hole in it. This time it's getting the pump rub fix from Merchant.

It's not that bad of a job, but you will need a clip ring tool to remove the rear case half and all the bearings. I'm sure someone has posted a DIY on here somewhere. If it's come to the point where it is binding you'll have to order new syncro's, mood fork because it will be chewed up. Ask me how I know this. You can get all the bearings from your local bearing dealer or you can order a complete kit seals and all for around 150 on the net. The syncro's will run you about 120 for all three components. Go ahead and order a new aluminum tail housing it will come with a new yoke bushing installed and the pump kit from Merchant Auto is worth the money. I've had to do this to both of my trucks.

If you get the case apart and the planetary is toast you may just as well get a new or reman case. Reman cases used to be cheap( relatively) through GM and came with the best warranty.

x2. If its been ran dry just get a reman. I pulled mine apart and it was toast, parts cost almost the same as a reman if theres to much damage. Plus that way you get a warranty. But if it hasnt been ran dry you can go for it, or pull it look at it and decide to build it or get a reman. My mainshaft, forks, pump, planteray were all shot along with everything else. Metal shaving were ran through it like most of them that ran dry.

It is very easy though. Pull both driveshafts out, disconnect all plugs/wiring, put a jack under the tranny and pull the crossmember out that supports the trans. Then you have like 6 or 8 nuts holding it to the trans(dont remember exact #). Take those out, slide it backwards a little then point the front of it towards the ground clearing the trans and pull it out forward(going towards the trans). It should only take like 30mins to take out given you have air tools or friends to help. I dont recall all the socket sizes for the bolts. Youll need wrenchs for the tcase nuts
