Clunk question

[Origommi]

I have a 96 GT and have started to hear a metal on metal clunk after I let off the clutch. It is most noticable when I go from first to second gear when I take off from a stop. I took it by the mechanic who though it might be something lose and when I take off it jars the engine a little which makes the noise. Any thoughts would greatly be appreciated before he tears into my car.

Hmmm... Maybe a CV joint?

Usually a 'clunk' is caused by a bad U-Joint(s). We don't have CV joints.

 

[Origommi]

If its a U joint... Would the noise come from the front or back?

It's got to be either be play in the rear diff,or your u joints,unless your trans is ready to go out the door on you!!
Jack up the rear and see how much play is i the rear by rotating the tire side to side by hand,then pull it back and forth to see how much play is that way.I currently have this issue with my diff,and it turns out to be my currier internals,and luckly is covered under warranty still and will be getting replaced soon.
And also while it up in the air,rotate the driveshaft side to side,and watch to see how much play is in the u joints as there should be none.The only play there should be in the driveshaft is in from the trans,but it should only be a slight paly hwen you rotate it side to side.

The sound is forsure coming from the front. It also makes the same kind of sound once in awhile if I push down on the gas pedal in a manner which would cause the vehicle to jerk.

That is because the sound could be travelling threw the driveshaft.
So i would check both the u joints,and rear for any sloppy play.

 

[Origommi]

If my trans was going would it make the same noise?

 

[DTNODYA]

If it's a grinding type sound then it could be your throw out bearing. But you described a clunk and that'd most likely be your U-joints. They are cheap, even to have someone else do them.

Might want to check the engine mounts. If one has failed, the engine can move more in reaction to the torque which might allow the exhaust to hit the floorboards. Check the trans-mount while you're at it.
