Yes and it can be done without pulling the t-case

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!

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.

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.!!!

I have never had to replace a t.case output shaft bushing EVER. Are you sure this is the problem. They should have a slight amount of play up and down for lubrication.

What kind of seal is it? An o-ring hook tool won't do it?
