Well lately every time I shift I hear a metallic thump/clunk from under the car. This happens when I let off the clutch after the car has been put into the gear I select. Is there any way to tell by doing a visual inspection? What should I look for? Are the mounts hard to replace? I'm doing an engine oil/diff oil change tomorrow so I'll be under the car to look.

 

Anyone?

 

Is it while you're letting the clutch out that you hear the noise, or after, once you start accelerating again? Is there some jerkyness associated with the noize? If it's after the clutch is engaged and when you get back on the gas it's probably a diff mount. If it's from the rear then definetely check the front diff mount, as it's known to break and cause a metallic clunking sound. Other than that it could be an engine or transmission mount, but that's unlikely.

 

A little of both. There is some jerkiness too.

 

Check the u-joints on the driveshaft, too.

 

clunking during gear changes like reverse etc... is diff mount. usually when the trans mount starts going bad you will get vibrations inside the car when you rev the engine, even in neutral.

 

clunk. clunk jerk jerk

sounds like a diff mount to me. I have the same problem


real easy to figure out go under the car and reach up to the front snout of the differential and push up. watch if move up fairly easily.



problem is it shouldn't

 

well it seems after i shift into and out of a gear like 1st to 2nd then into 3rd as soon as I let off the clutch and get on the gas is when the clunk happens.

 

have you fixed your issue...
I have the same issues and have pinpointed the front diff. mount..
I have a thread on it today...

I would like to find a write up on how to replace it... what have you done?

 

There is a sticky on the FAQ if I recall correctly!
