what is the proper way to check your u-joints and driveshaft, to see if they are still good.

 

I usually put my transmission in neutral, crawl underneath, and work the shaft (rotating) back and forth while watching the u-joints for unusual movement, also for "noise", clunking------ just make sure you can differ from slack in the pinion and movement (clunking) in the joint/joints, it's usually pretty obivious, just do it slowly and watch and "feel" closely.

 

With wheels off ground so can rotate through complete revolution may give better feel of joint condition.

 

Thank you--------- my bad------ "old" timers kicking in on my part.
