About a year ago I dropped my rear drive shaft and greased the output shaft splines due to a bad clunk upon braking and accelerating. Well a few months ago it already started clunking again. Anybody experience this problem before? Wish there was a grease cert on the drive shaft for this! I know the DS isn't hard to drop, but last time I did this a bolt head got rounded and I couldn't get it out so I pried open the bracket to get the DS out, so when I went to re-install it I couldn't get the other bolt lined up because I deformed the bracket by prying it open and I think I cross-threaded it...stupid huh... Anyway I don't think it's normal for the greasing not to last very long?

 

I'd be looking at the U-Joints and maybe the differential for the clunk. (first). Myself I'd go to the JY for the bolts and parts.

 

UPDATE: I inspected and cleaned my rear brakes this weekend and found that one of them was way out of adjustment (too tight), so tight it was hard to pull off the drum, so I backed it off and the clunk seems to be gone so far.

 

It's not normal to grease those spline's,thats why there isn't a grease ZERK fitting for it.

 

That's good....I don't want to grease it anyway...
