guys, the other day i had to mash the brakes due to an ass hole in front of me. from then on, every time i use the brakes, i have a clunking under the car by the hump on the pass side. brakes are good. the clunk only happens when i hit the brakes. levent says it is probably a broken rubber mount by the bell housing that is letting the drive train slide forward. i loaned out my jack and stands for a few days so i can't get under there. does any one have a pic of said part/mount/brace?

Could be a few different things, definitely inspect before you buy parts.
Also, the only rubber bits next to the bellhousing I can think of are the control arm bushings, that wouldn't make the drivetrain slide forward though (do you still have a radiator? lol) -
yes, i do have a rad. lol. but i was told to look at the rad and inspect for evidence of damage. the sound is not a random one, what ever it is, it is with the revolution of either the wheels (which i doubt cause it seems to be in the middle of the car) or the drive shaft. she accelerates strong and cruises w/o any noise or vibration. only on braking does the problem occur.Originally posted by jalopi View PostsigpicComment

Streetable poly mounts, trans mounts are here!

Levent was probably talking about the trans mounts. They are like miniature motor mounts.

not the trans mounts, there fine. he said it's by the bell housing where the trans is connected.Originally posted by NitroRustlerDriver View PostLevent was probably talking about the trans mounts. They are like miniature motor mounts.

Call me crazy, but I'm pretty sure that part number 2 in that diagram is a trans mount.
I'm no e30 expert, so I can't speak for every model ever made, but there are no drivetrain mounts (as far as I know) between the engine mounts and the trans mount. The only bushings someone could misconstrue as drivetrain mounts/bushings and are right next to the bellhousing are the control arm bushings.
Have a friend get in the passenger seat and take a video so we can hear the noise.Comment

my bad, that is a trans mount.Originally posted by jalopi View Post
i'm wondering if the csb broke free? it sucks i cant get her up high enough (lent jack to friend) to pull the heat shield. only makes the noise when braking and it is definetly against the hump between the pass seat and the console.sigpicComment

There is a mount that keeps the engine/trans from shifting forward but it would be difficult for it to fail. If the noise and rubbing happen at the tunnel between the seats i would look at the trans mount first.Lorin

trans mounts a only 3 years old and i was able to get under there enough to confirm that they are ok. what is the mount that you speak of?sigpicComment

Do they visually look OK or did you try jacking it up a bit to see how far the engine/trans moves?Comment
