I will check track arm bushings can those be bought or do you have to buy a new track arm, and no i have not fixed the rear track arm will that help the problem with the front. i also replaced the drivers side motor mount it was gone the front drive shaft was shot could the trans mount be bad and cause it to shake. And for the tie rods wouldnt it shake with out hiting a bump at higher speeds? this thing drive great until i hit a bump,it doesnt pull and the steering wheel doesnt shake at all it just feels like the brake and clutch pedals are going to fall off because they are shaking so bad and it feels as the hole jeep shakes.
