sounds like bushing or gone in the back but not sure which ones absorb the power when coming off the clutch. Help. Diff mounts??

 

It sounds like your front diff mount. Mine has been bad for a while now. It just gets louder and louder.

 

will a diff mount also make noise just while you are driving. cause mine is doing the same thing.

 

yes it will, like a clunking sound while you are accelerating?

 

or when u let off the gas......

 

Yeah man, definately the rear diff mounts. Got the same deal on mine, just not as bad yet. I've heard of welding on some steel reinforcements opposed to replacing them....but like I said I'm not there yet.

 

did you check your universal joints...the one just before my differential is bad and it clunks everytime i let of the gas or shift somewhat hard..could be your problem

 

Its the front diff mount like said above. I just solved the same problem and it was to install a new diff mount..

 

apparently when tuffy muffler had my car up in the air and the service guy grabbed the universal joint and moved it about 2 inches causing a very prominent clunking noise i was seeing things..possibly acid flashbacks..it seems to me both problems would have similar symptoms..do you have major vibration when going around 60 mph?? im not saying im right and everyone else is wrong just offering up suggestion

 

Yep i have broken 2 mazda stock ones and got a mazdatrix one without the counter weight and its way stiffer and stronger..It's just the rubber is weak and frail..also rx7's arent really made to be peeled out..more for road racing..so u draggers it could break many times =) i have broken 2 1\2 lol =)

 

i have the same prob, when i let offf my clutch or downshift a klunk occurrs, when i had my car up in the air i found it was the crossmember that is in the middle of the tranny...i just got the part putting it in tomorrow i'll let ya know if it solves the prob..it should come all as one part from mazda (the crossmember and two square mount that need to be atached before installing)
