i have a 89 jeep cherokee limited. it started vibrating really bad only during acceleration at about 30mph. i found out that my driver side motor mount was bad and my tranny mount was bad, so i replaced both and it still shakes during acceleration, just not as bad. what could it be??[img:dd47073c0b]http://www.2carpros.com/forum/automotive_pictures/179102_01020001031201041020080114b915651c0f5d2724510055a7_1.jpg[/img:dd47073c0b]

So you did check all three mounts right? If they are all good, check the front end, especially the track bar.

When was the last time it seen a major tune-up? For a start check the throttle position sensor

Is it a motor shake, skip? or a front end shake?

The third is the other motor mount...I.E. 1 on each side, and your tranny!
