well on my 88vert every time i apply or relase the clutch i get a big clunk sound and i can feel it,so atfirst im thinking diff mount right?wrong.i got it up on a hoist and diff mounts are good but the kid i got it from didnt put the tranny mount all back together,so ok it was the tranny right?WRONG!!!!**** me what am i sposed to do!?!?!?!the rear suspention bushings are a little worn out but not bad enof to make an extreem CLUNK!!so sum one please help me!!!

 

Sounds like a transmission problem to me. (EDIT: For clarification - it sounds to me like the clutch isn't releasing ad engaging properly withi the transmission bellhousing.) Time to drop that tranny and check her out! Also, have you checked your clutch slave cylinder? If the clutch isn't releasing all the way / properly I would imagine you'd get a clunky sound.

Also, if it had been the front diff mount you wouldn't have heard a clunk so much as you would have felt it. And it would occur on accel / decel more than putting the clutch in / out. I know, my front diff mount came off in two pieces. :-P

Sounds like a shot throw-out bearing to me - or a loose flywheel. I'd be hoping for the throwout bearing.

 

Are you getting any vibration on the road? For me it was my U joint shifting and clunking. Most of the time I hear it's the diff mount though.

 

well i know my throw out bearing is about to go,is is makeing a whineing noise that makes you want to drive a buck knife into your ear.and i checked all diff mounts and all are in good shape and the diff is in there solid.no viberation going down the road and the faster im going the harder the clunk it seems.ill check my slave cylender now,im going to feel SO DUMB if it is low but i will be extremly happy.but ither way ill let yall know when i figure it out and i aprechiate all the help i can get.

 

ok so i checked my fluid and its fine,then i went to check my lines and there is one going from the slave to the tranny,and then coming from the tranny there is a fitting,but no line?wtf is this?HELP

 

sounds like the release bearing...

 

Are you talking about a bleed fitting perhaps?

 

Is the clunking from the back of the car? There are TONS of bushings and mounts back there that can go bad. I need to replace just about all of them on my car. Just gotta' keep driving till i get a DD though .
