Noticed today on my t56 that it was wet wit oil where the end of the tailshaft is im guessing those seals go bad??

fleetmgr

Yup, they do. They are also easy to change.

Mines leaking too. Does it just slide out?

joecar

If you have many miles, then also check the bushing on the back of the trans... if it is worn then this will allow the yoke to wobble which will cause the seal to leak.

Midnight00SS

how do u change this thing?

fleetmgr

Remove the seal with a seal remover, and tap the new one in. Same as a wheel bearing seal.

The bushing behind the seal takes a special puller/installer, but Joecar is right, you should change it too.

Midnight00SS

ok so i should prob replace both?? it cant be too expensive im guessing?

fleetmgr

Naw, it's not expensive....and I think you can rent the puller from AZ and the like.

Would this seal also be called an "extension housing seal". Thats what ive found on GM parts direct, just wondering if its the same thing.

fleetmgr

Not sure, but something like that I wouldn't get from an online site anyway, for a couple of reasons:

1. From the parts store, it'll be less than $10.
2. You can't match it with the old one.
3. There's no good reason to pay the extra to have an OEM seal. They buy theirs from the same manufacturers the parts stores do.

I am in the process of doing the same thing. I cant find the Bushing though on AZ site.

O reillys said they cant get them, neither could the other parts houses. They said go to the GM dealer. My local Chevy dealer wants $53 for one. So I looked on GM parts house and its only $8. If thats the same part.

You might also look at some of the site sponsors here, like D&D. Bet they got 'em.

Midnight00SS

wut is the part #'s that we need for the both of them??

just replaced the seal and bushing part number 5200 at Advanced and AZ $7.99. the bushing is really tight though. Im thinking once I put a few miles on in the driveshaft will break it in.

Looks like im going to Advanced tomorrow. Was it hard to do?

No, took a lil while to get the bushing off. I did not have a puller so I bent the tip of a skinniy flat head and just kept pulling on the back of the bushing and a little banging and finally got it. Just a regular seal puller will do the trick for the seal.
