ok im in the middle of replacing my diff mount and i got some questions:

i have the old one out, but it doesnt look any differrent than the new one going in. both look to have the rubber block with the 2 studs fully intackt. how can i tell that the old one was broken? was it?

what the heck is that mettal block for that hangs off the front of it? i cant figure out what on earth that thing does and im tempted to take it off the new before installation. someone please enligten me?????


so lets assume the old diff mount was ok? what else could give blown diff mount symptoms (clunking on acceleration and throttle lift)? EVERY bolt on the subframe and diff was tight (and rusted, grrrr) and there was no vissible slack anwhere in the assembly when i droped it to switch the mounts. is there something i could be missing thats causing the problems besides the diff mount?

thanks

bump???

 

me and my buddy just had the same problem, ended up being his diff was bad so he just got a lsd from the junk yard and put it in, grab each axle and yank it to make sure 1 of them dont clunk thats how we found his problem

good luck

 

Check the metal portion of the mount. Thats the part that usually breaks.

 

hmmm metal part is fine. i hope its not the diff itself

wouldnt that make funny whinning noises if its the diff?

 

i dont know, my buddies wasnt, it was clanking just like when the mount is broke so we spent time dropping all the stuff to find out the damn mount was fine,i was so pissed cause i live in fl. and its like 100 degrees outside every day,then we found the diff problem

 

andrew look really hard at it. i knw when i brok mine its hard to see but if its clunking in the rear its the diff mount. and the thing no the front i haev no cule about it. my competition mount didnt have one.

 

The block hanging off the front is a vibration dampener.

As for the clunking... did you check the diff housing bushings? I had all the syptoms of a broken diff mount but when I dropped the subframe I found it intact. It was actually one of the diff housing bushings.

 

I believe Kevin Landers gave a good way to test the diff mount.

Cruise in first gear to about 10mph and let off the gas and repeat. If you hear a clunk sound its the diff mount. Something to that effect.

 

I've got some mad clunking in the front on acceleration... im begining to think its motor mounts... actually ive got a good idea it is

 

It's *usually* the diff mount. If it's not the diff mount then it's probably the diff housing mounts.
