Rattle after shifting

So whenever I shift to 2nd and sometimes 3rd there is a little rattle/(kind of a clunk or something shifting back and forth) right after I shift into the gear. Tried to look up it on here and JF and haven't found anything similar to what it sounds like.

My thought is maybe the trans mount is busted and its moving after shifting. Or maybe the motor mounts? I'm not sure what it could be though. Any thoughts would be great!!

Also got another clunking sound going on when I turn hard in a parking lot. And I know it could be a lot of things like the track bar or steering bushings. Any idea where to look first?

Thanks!!

I think you are on the right track of things to check...check your u-joints and exhaust sys too.

had a really weird 'wirlling/grinding' noise when shifting. would only last a split second and not all the time. thought for sure it was the throw out. crawled under the jeep and pulled/pushed on everything-turned out to be the exhaust heat sheild was just barely holding on. evidently at certain rpm's it would vibrate causeing the noise. ripped it off the rest of the way and no more rattle and haven't noticed any problems with it gone.

I think my jeep may be doing something similar. Ive noticed in my jeep that when i put the clutch in to shift out of 1st and sometimes 2nd at around 2k rpm it occasionally will give me 2-3 knocks/clunks (no unusual noise putting it into gear though). Only thing is, if I take the rpms up higher to 3 or above it comes out of 1st and 2nd with no noise at all and is perfectly smooth.

I have that rattling noise as well, asked my dad and he says it's the throwout bearings in the tranny. I noticed it only happens when shifting into second and third at a slow speed where vibration occurs, starting to think it's not the beaarings after all. Makes my Jeep sounds cheap and crappy tho. gl

You might be talking about the play in the drive shaft coming out of the tranny. Mine does the same thing. It is almost like the drive shaft has to catch back up with the gears that are connected to the spline. Get up underneath the Jeep and turn the rear drive shaft and see if it sounds familiar.

As for the steering clunk, it could be your u joints, especially if you are in 4 wheel drive.
