Driveshaft adjustment?

[chris89]

I was putting my car back together the other night, reinstalling my transmission and driveshaft. I noticed that it looks like the driveshaft is adjustable where the center bearing bolts up to, I'm guessing it was out of adjustment because it was leaking a little bit at the back of the output shaft, Should i just push the driveshaft as far as it'll go into the output shaft on the transmission?

The DS isn't adjustable that I know of, the center bearing has two washers that space it down from the frame. If you don't have them then you need to get some. They help line up the DS, up and down, Also your unis should all be in line with each other to be in sync.

I know whats hes talking about, the carrier bearing on the two ends is kind of "slotted" so it allows the driveshaft to be slid a little forward or a little back... overall it isnt much, but have you replaced the driveshaft input seal?

Time to hit rehab guys.....

Once the Shaft is bolted to the Diff it's NOT moving front/rear.......

Side to side and Up/down is another matter as AJ pointed out.

Not too much play front to back, a little more side to side for alinement, I always mark my bolts before I take the bearing off so I can locate it in the same place. But like I said you should have a couple of spacers that go inbetween the support and frame approximatly 1/2" thick and the bolts go thru them.

if you put everything back together and then you notice leaking in the rear transaxel what kould the problem be?

Torn/brittle seal.

The thing about it is the seal seemed fine, it looked like it was in o-k shape.

The slots are there to allow for variations in driveshaft length and the distance between the end of the tranny and the differential flange. You have to shove the shaft completely into the transmission to get it on the differential, then pull it back to seat it on the diff flange. Where the holes end up is where they end up. The bolts holding the carrier to the car should get tightened after the bolts on the diff flange.
