Two problems, overheating a vibration.

[50POWR]

I had quite a vibration problem, swapped out the driveshaft and it went away. Do you have a friend that might let you "borrow" his driveshaft long enough to put it in your car and take it for a drive? (its only 4 bolts) Thats what I did, just to see if that was it for sure, and thats what it was. The yoke on my driveshaft was really wavy, and I was told that could be the reason for the vibration. By the way, my vibration problems started at about the same time my tranny died also.....
