alright i have a 92 lude and it shakes somewhat around 60 mph. but really only when i press the throttle. however it does not do it all the time. i was told that it could be some sort of ball joint going bad.... any ideas?

 

blown cv boot on axle, allignment, wheels unbalanced, wheel bearings, could be a lot of things

 

i just got it aligned and balanced so i know it is not that. i also just replaced a tie rod end.

 

Balljoint sounds right if you got the wheels balanced already.
