i have a 97 2 door 4x4 automatic i just got this back from my mom( i let her drive it for 2 years) and it starts shaking bad from 30 mph and on , it gets worst the faster you go. if i let off the gas it stops but as soon as i get back on the gas it starts again so, whats is bad im guessin it is eaither the torque converter, drive shaft, u-joints- or the rear end thanks for all your help

 

have you checked the tire balance? thats the first thing to check!

 

no i didnt think about tire size because it only does it when i hit the gas and quits when i let off

 

How are your motor mounts looking? Also check your U-joint on the drive shaft; does it do it if you put the trans in neutral and just race the engine?

 

It sounds like a U-Joint to me, but do the neutral test too. I had the same issue, it turned out to to be a U-joint, except mine was squeaking too.

 

thanks guys i had it in park and when i race the engine the motor does shake some but deff not it im off tomarrow so i will put 2 new u joints in
