Rebuilt Driveline and Vibration...Need help/advice
I already read the other post regarding a 94 Cobra having a vibration problem and took what great advice you had there and am using that to potentially help me with my problem, but I wanted to exactly describe my situation to see if anyone else has any further advice or potential answers to my problem. Ok, so here it is.
Just finished replacing my entire driveline after I had previously blew out my stock t-5 tranny, clutch w/pressure plate and all, cracked the bell housing in the process, and broke the yolk bearing on the driveshaft. I had it replaced by a very good, and well known mechanic with a great reputation, so I am almost 100% certain it was all installed right. I replaced everything with a brand new tremmec tranny with a Pro 5.0 shifter, new Spec Stage 1 clutch, new yolk bearing, and new bell housing of course. Everything was brand new with all new mounting hardware/clutch hardware that is needed. Mechanic finished it yesterday and took it for a test drive and it had a vibration he said. The vibration as he explained it was slightly more pronounced at the lower RPM's, but was still consistent through the uppers as well. I know from reading the earlier post that it may be my flywheel that is warped/defective as this is the only thing I did not replace, but just had it turned instead. I understand this may be one of the causes and have told him this already. However, if my memory serves me correct, I think I remember reading a post by someone that mentioned that a new Spec clutch will produce a vibration until it is "broken in" and may even be still present even after this. I was wondering if anybody else has heard of this or knows anything about this?? If so, maybe ill see if it gets better after I drive the car very gently to break all the stuff in. Of course, any other recommendations/advice any of you may have I will be more than greatful to hear, as I just want this problem fixed and to get her back on the road as its been too long. Thanks all!
