Bad Vibrations

Is it possible that a bad tranny mount would cause an odd u joint vibration? When I hit the go pedal, I get a vibration, and when I decelerate, it vibrates also. I replaced the rear joint just recently, and the front joint is still in great shape. I am going to pry on the back of the tranny/transfer case to see if they move on the crossmember, but I am not sure that this is even causing the problem. It is driving me nuts. Any help would be appreciated, thanks.

Re: Bad Vibrations

did you drop your driveshaft off the ground? or accidently hit the drive shaft tube when hammering in the new u-joint? [img]images/graemlins/censor.gif[/img]

Re: Bad Vibrations

Well, the driveshaft is really rusty. This did start about the time I changed the joint, or at least got way worse. I did not hit the driveshaft with the hammer, but I did hold it in a vise while I changed the joint. The shaft did seem a bit brittle at the time. However, it does this sometimes when the truck is not moving and in gear, when the shaft is not in motion with the brake applied. Any clue?
