CV Driveshaft

[TheJDMan]

Update, I have been chasing a drive line vibration for the past three years. First I found a thrust washer missing in a cap of the original rear Spicer U-joint that was installed in my custom drive shaft. As I mentioned in a previous post in this thread, I installed a NAPA U-joint to replace the original to get the car back on the road and later ordered a pair of Spicers to keep as spares. Well I never suspected that the replacement U-joint might also be bad. In any case, today I removed the drive shaft to work on fabricating a DS loop and was stunned to discover that the rear joint I had installed last year was seized up. So I installed one of the spare Spicer joints I had and put everything back together. I still need to get it out on I95 for a sustained high speed run to make sure but it seems my remaining vibration is gone now. So for the past three years total I have been chasing a vibration which was first one U-joint improperly installed and then just my luck a second bad joint. Go figure.
