I'm going to be doing this soon..I'm loosing about 3 drops/day when parked. How long did that take you? Degree of difficulty?Unbolt the drive shaft from the rear axle, and he carrier bearing, and it will slide right out of the transfer case.
Then tap the seal out and tap a new one in place. Bingo!
What kind of seal is it? An o-ring hook tool won't do it?I did no know this when I did mine!
I took it out and then found that the rear case half had a hole in it due to it running out of oil and the bearing binding up. I bought a used case for $100 and used the parts to build a good one.
The seal was a pain to take out and I completely wrecked it, but It should take you about half an hour to do the job.
Hopefully someone will chime in with a good way to remove the old seal other than beating on it with a hammer claw.!!!
Not necessary to pull the t-case to do the bushing. It can be done in the vehicle with the proper tool, GM TOOL # J45380. That is what I use to do it in the vehicle. Just make sure you need a bushing, when the seal might be your only problem.Sorry guys I mis read the post....I was talking about the seal.
You would need to take the TC out, and take it apart to do the bushing....
My local tranmission shop told me he could not get the bushing and that I would have to replace the rear half of the case.....But Merchant Automotive sells a new busing for them so I think it can be done.
It depends on the amount of play between the yoke and bushing.How can a person tell if it is just the bushing or the seal. I have a small drip also and was curious what parts I might need.
As stated before, it can be done in the vehicle with GM tool #45380, see post#11 in this thread. Also if you don't have a factory manual, it is an excellent reference. They are available from HELM Inc for about $150-160 shipped to your door, worth it in the long run.......so i anyone has done this without removing the case let me know.......
