Lately whenever I excellarate (under power) I have a vibration feels like its a joint on the drive line, I have chk under and so did a friend and we cannot locate any looseness on any of them
When I just coast there is no vibration. Anyone have a clue on what it could be?

 

Take the drive shaft out and take a good look at the ujoints...... I had a problem like this before Christmas....... back joint was dry and needles were rusty....... new joint in and all was good......

 

X2 I had a vibe at anything over 80k with my front shaft. Replaced both U-joints and re-greased the slip joint and it went away.

 

Tks guys I had it ckd and the fellow couldn't find the fault, so this week going to an expert in this line for his opinion if anyone is to find it he will, will post what it is when I know.

 

Rear universal on drv shaft near diff shot (changed) also had front dvr's wheel bearing changed slight grinding noise and very slight looseness..not a cheap job all toll but had to be done. I noticed at this shop they do a few little extra's when doing ur job, they clean stuff which I have found in many places just a little shotie when that extra counts in doing the job right. If your near Mtl here's the place ask for Jeff "Joron Automobile" their on Papineau near the Jacques Cartier bridge. They have a fabulous calendar all older car pictures :)
