Driveshaft Removal

[89tta636]

Is the trans seal before or after the slip yoke on the 200 4R trans? Should I expect a little bit of trans fluid to run out when I pull the driveshaft?

Thanks.

the transmission rear seal is in the tail shaft of the transmission you will not have any transmission fluid run out when you remove the drive shaft.When you remove the seal then you going to have some come out not much good luck.:cheers:

Thanks pont1230.

I have an annoying clunk that happens as soon as the rear axle moves over a bump, dip, even rolling out of garage backward without the engine running. Replaced all bushings thinking they were old and all. Still had the clunk. Some additional research on the web indicates that many GM cars and trucks experience this. The answer is packing the slip yoke with heavy grease, but I wanted to make sure the grease couldn't get into the trans fluid. Some people have gone as far as installing a grease zerk in the slip yoke so they could add grease easier without pulling the driveshaft. If the grease trick solves the problem, then I know it was the slip yoke slapping or binding. The next answer is to replace the slip yoke with a better nickel or chromoly one.

If you google "driveshaft yoke clunk" you will see all the results.

Will post my results for others to see in the future if they ever get the clunk.

Btw. Car is relatively low mileage with 32,000 miles and it has been doing this since I bought the car at 24,000 miles.

If you pack the yoke with grease it will not slip on out put shaft as car rolls down high way lite coat on splines may be I would not pack it

Got it. I know grease doesn't compress, so wouldn't put too much in there.. But I do want to try to dampen the clunk.

Thanks..
