Well, I have decided to put up another tech article. This one is way over due. I am not trying to re-write the shop manual here, just point out some often overlooked issues.

You are welcome. Thanks for checking it out. I know it needs some proof reading, and I have more pictures for the article. I am getting to it.

Greg please advise,
While putting a motor in my GTV6 I decided to have my driveshaft balanced by a tech shop that does alot of Paul Spreull's work and so on here near Atlanta. They said that they didn't have the machine to balance it with all nuts, bolts and guibos so I settled on allowing them to split the balancing into two parts. When I installed the driveshaft and had the car ready to go (after revving and the pinch bolt business along with leaving all bolts a little loose to let the centering take place) the driveshaft vibrated like total hell at 2000 rpm. So I yanked out the driveshaft and balanced all of the nuts and bolts carefully locating the same mass bolts 180 degrees across one another. Still vibrated like crazy!! It wasn't until I got under the car and spun the driveshaft at 4500 rpms with a paint brush and some white-out did I find the heavy side to the shaft. I weighted the opposite side with an extra long driveshaft bolt, about 4 washers and an extra nut that I was able to get it to spin true. What is the problem?

I had mine ballenced as a whole. but I have replaced all the ruber parts at lest 2 times and it is still great. Is the centering bushes there and good? (guessing it is like the Milano with centering bearings at each end.) if one is missing or bad the shaft can get off center other then that use of hose clamps seem to work well for adding some weight, just put the screw end on the light side.

the hose clamp is a cool idea where did you learn that trick... my spider drive shaft doesn't viberate but my mazda's does like you would not belive... THANKS!!!!

This shaft needed some serious weight on one side
it must be the index on the spline or something!??
