when installing a one-peice driveshaft, it it just pull out and replace and you're ready to go. My car has vibration at 40mph, and i'd hate to keep unbolting and rebolting pipes/driveshaft to get it right.

that's all there is to it... you may have to grease the fittings to further prevent vibration, but that should be detailed in the instructions provided from the manufacturer of the driveshaft.

well my friend's Z had a vibration(at the the same MPH). At first we thought it mighte have been a bent rim (Because it was new to him). we had it checked, and that wasn't it. Then he was told that it COULD be a bent driveshaft, so he replaced it to a one piece steel driveshaft. And that WASN'T it either. After a while, he had to change the clutch, and the guy that did the work pulled the flyweelm, and said it was warped pretty bad. And ever since he replaced the flyweel(oem), it hasn't made a vibration.

the chances of that happening are pretty slim tho. most of the time it will be a driveshaft problem

when i emailed the z1 guys they said the driveshaft would have to be clocked. could anyone let me know how to measure the runout on the driveshaft?

stick a dial indicator on it and spin. adjust 'till the play is dialed out. simple.

thanks. i think i'm gonna try to clock my stock driveshaft first to see if that fixes th problem becasue its just a slight vibration at 40mph. If not i guess i'll pick-up the steel one-piece this guy is selling. I know its not the aluminum but for $100 you can't go wrong. Mahalo

Well, technically you coul go wrong.....if it's not properly balanced.
