I went through the archives and the manuals I have but didn't find anything that answered my question. Should you grease your U Joints? If yes, with what? I know very little about U Joints. I am a little concerned about them because one of the caps fell off when I was putting my clutch in last year. Being the rocket scientist that I am, I just picked the cap up, made sure none of the needle bearings had fallen out, and put the cap back on.

Do You Have Grease Fittings On
the "U" joints? If so, lubricate them with chassis grease. If not, leave them alone.

Re: How do you tell if their bad?

The best an easist way to tell if a u-joint is "bad" is to examine the u-joint trunnions. This is the machined bearing surface upon which the roller bearings ride. Look for brinneling, pitting, or other damage. If ANY is present, and I mean ANY, then the u-joint is scrap. All it takes is for ONE of the four trunnions on a u-joint to be so-damaged to render the u-joint unserviceable and unfit for re-use. If your u-joints have 10-15 thousand miles on them, what are the chances that at all four of the trunnions on each u-joint are NOT so-damaged? The answer is slim to none. This problem is especially prevalent with half-shaft u-joints which are more heavily loaded and worked than drive shaft u-joints. That's why I only recommend the use of the VERY HIGHEST quality u-joints on Corvettes. For me, that means Spicer ONLY.In Appreciation of John HinckleyComment

Check for play
by working the shafts back and forth. If off the car do as Joe says inspect visually.
