ok i am trying to locate my diff mount to stop my car for clunking during take off i had my car up on the lift but i just can not seem to find which mount it is.

 

It is the one on the front of the diff that gives everyone fits- mounts it to the top of the subframe.

Drop the subframe and diff to replace it. Easiest way.

I am a fan of welding a plate across the mount to make it solid. Cheap, effective, and nearly free.

Don't be surprised if its not the mount at all but the tab on the subframe that the mount attaches to is what has actually broken. You will still need a welder to fix it or a new subframe.
