Clutch/Vibration

Hi all I have a perculiar problem. I just replaced my clutch on my 1996 S-10 pick up. Basically all stock, 4.3, 4X4, just a few goodies from DeeZee and some K&N stuff. Anyway like said earlier I replaced my clutch, concentric cylinder, tension spring, pilot and release bearing. The clutch is a top if the line OEM. And Yes I had the flywheel machined. Now to the problem, I have a terrible vibration when taking off in first or reverse. It only happens when taking off from a dead stop... I bled the hydraulic system thoroughly, I thought. Could there be some water or air in there causing slack? I am puzzled, I did not go with an overly aggresive clutch like a dual friction CenterForce because I wanted to avoid this. Well if anyone could shed some light on this dilemma I would be very appreciative. Thanx all....

Re: Clutch/Vibration

Hi, don't know mutch about clutches but my father had the same problem with his car. It seems that one of the springs of the clutch assembly of his car (and yes it was brand new also) did not have the same strenght has the other ones on it so it created a vibration every time in the first gear. And almost unoticable in the others. So you might want to check the clutch assembly you received and If you can try another new one. I know that on My fathers car, It solved the problem. The clutch you purchased could have a manufacturing defect even if it is of good quality. That just a thought though. I never took off a clutch so I'm not sure which springs they were refering to. Hopes this helps a bit.

I have the same problem w/ my 84 s-10 5spd. Is is a 2.8L but just last March I replaced my clutch I didn't notice it at first but the virbration is also terrible in first and in reverse, I try not to give it too much gas but it will stall and if i give it too much gas it will vibrate like crazy, well I just threw a bearing and it scoard the crank so I gotta new engine..I was pondering to get a new clutch even though mine is brand new...I just gotta get rid of it..

Re: Clutch/Vibration

First check your U joints over really well, even if you can't move them when its parked does'nt mean they are not bad. It does kinda sound like you have a bad pressure plate but not sure. If you think you still have air in the line try bleeding it more. On my 83 I had to jack up the passanger side way up in the air to get all the air out of it. Good Luck

Re: Clutch/Vibration

Thanx all for your insight, I am going to try bleeding the system again. I sure hope that I don't have a faulty part, I REALLY do not want to have to take that tranny out again. I live in Minnesota and if anyone has been watching the weather lately it's butt cold here and my garage is only partially heated. Also, it's just a plain pain in the ass. Again thanx to all respondents.

Re: Clutch/Vibration

Is it possible your rear oil seal is bad? Oil could cause the clutch to be grabby or even vibrate when starting up. Is it possible that your throwout bearing was not seated properly so that it only pushes on half of your pressure plate springs?
