Chatter/Noises - things to look for.

Hello all! - I Just bought my first jeep - 94 yj 2.5l.

Currently, if I tap the gas while driving I hear chatter/clanking. I also hear it when hitting a bump. It sounds like its right under me. I took a look and I see the transmission mount isn't in the best of shape, so I'm going to change it. I don't think the mount is the only thing wrong. What else should I look for while I have this apart?

Thanks for the help!

Yeah a sign of all mounts. When the tranny one goes bad it puts a strain on the motor mounts might want to check those too. There is also supposed to be a torque arm mount right there also.

The first thing I'd suspect is the transfer case skid plate on tight?

Transfer case/skid play are all tight and not moving.

I noticed the motor jumped while in reverse, so I checked the motor mount. It was bad, I replaced it the next day.

W/ the torque arm - How do I tell if its bad?

Could be exhaust too... Check for a loose cat shield, or maybe a baffle inside the muffler let go. (Plauged with that one right now, and accidently ordered a TJ cat back from Summit and had to re-order!) But that is making a nasty rattle and does not present itself as a muffler problem at all. I had to crawl under the Jeep ahd have someone start it to find out it was inside the muffler. My exhaust is rock solid tight too!

Agree with the mounts (tranny and engine) being suspect with noises on take off. As far a rattle when hitting bumps or wash board, if the noise seems to transfer through the throttle pedal and sounds as though the radiator is rattling around or perhaps sounds like a loose shock mount,... then try placing a folded up wash cloth under both hood hinges across the cowl and close the hood on them to test. It is somewhat common for the cowl weather stripping between the cowl and backside of the hood to collapse and allow the hood to rattle against the cowl. If this noise goes away, then replace the stick on type weather stripping on the cowl.
