1992 Chevy Suburban Hard shifting
Transmission problem
1992 Chevy Suburban V8 Four Wheel Drive Automatic 315000 miles
When i shift into reverse, primarily when vehicle facing downhill, I hear a loud clunk. I suspect the transmision. So i had 2 diff friends listen to the clunk. They hear it from the rear end of the vehicle.So I replaced the U joints in hopes. That didnt do anything to help. Still shifts hard. But sound comes from the rear of the vehicle. Any help would be greatly aprreciated. How do I fix/check a rear end or tell if its the trans???

check for freeplay in your pinion.... (grab the yolk and look for freeplay in and out).... let us know what you find there.

I did that when i redid the u joints. It has a little bit of play but not very much. Old guy I was with said mine looked normal.

How much freeplay is normal?
Replied on September 27, 2010
anything you can see, or feel is to much.... the endplay is set to such tight tolerances, that any play felt will verify a problem.

Id say there was a least a 1/4 inch play. So whats my next step? And thank you

And why would the CLUNK sound come from the rear????
Replied on September 29, 2010
remove the rear diff cover... it is possible that a tooth has broken on either the ring gear, or spur gear... that would def. cause a clunk... let us know what you find.
