Drive Train Axles Bearings problem
1991 Chevy Silverado V8 Four Wheel Drive Automatic 179000 miles
Hi, I need some opinions, I have a 1991 k2500 silverado with auto trans. Ive been getting some serious clunking in the rear, usually when shifting without a load.
-under hard accel. She shifts, sounds and feels good,
then when I get off the throttle she will shift again to drop the rpm's and then " CLUNK".
-same thing when getting off the hwy offramp an intermittant single down-shift clunk.
-also while coasting (say 35mph) give her a little throttle and " clunk"
-i grabbed the rear driveshaft and all feels tight in all directions. I dont hear any whinning, and the trans. Is rebuilt a year ago and shifts strong. In the driveway I went from drive to reverse a few times thinking maybe driveline lash between pinion and ring gear and didnt hear any big clunking. Ive lubed some of the rear output shaft splines on some of the newer gm trucks per the gm tech. Serv. Bulletin and this doesnt feel like that.
feels like some slop in the rear end, whats a good way to troubleshoot theese symptoms. Thanks!
