Default Another problem.. Bumps at start...

Ok so my jeep now does this rapid bumping at start... In 1st gear if im at a stop and start driving again, it wil bump rapidly and then be fine through the rest of the gears.. Sometimes ill be slowin down and just shift it to 2nd cause I didnt fully stop and it will bump a little... idk what it is... Also it won't happen every time (usually does it when more gas is applied like a faster start) it happens 50% of the time and its never the same sometimes it bumps 2 times others it bumps 10 or more... It moves the entire car and you can hear it happening.... If any questions let me know... Suggestions ect.. I need help bad!!!

Get your grubbies on, grab a flashlight, crawl under your Jeep and look around at the motor mounts and trans mount. Missing bolts, rotten rubber?

I think you're missing the point. We can't see YOUR Jeep from here and it sure isn't gonna get diagnosed and fixed using a keyboard and monitor...................Some owner participation is in order.

Well I don't know what to look for our have any idea.. Mounts all look fine.. Noticed it only when I'm goin slow and when thr clutch is at like a little les than half released... If it is at that one point out will do it... if I get a quick release of clutch it's barely gunna do it
