Front and rear (rear) driveshaft joints are different?

[89Vette]

But be cautious, replacing/rebuilding my driveshaft fixed my vibrations for a while, but they came back and until I corrected the angle of the rear pinion angle the vibrations would always come back eventually. Mine used to even go away for a few days after greasing the U'joints and spline on the driveshaft.

In the future just call Independent 4x. One 5minute conversation with them and I knew what I needed to order and from who and that the Ujoints are different, but my driveshaft shop didn't even need the info they just took measurements and had Ujoints in stock and fixed it up same day :-)

Sorry I didn't see this thread earlier. I hope your vibrations do not come back but if they do, look at adjustable lower links for the rear to correct pinion angle problems.

Yours is lifted though....Currently, mine's not. OTOH, I was curious how high I can lift w/o issues. For example, I was considering a 1" or 2" helper-cup (vs springs). Of course, crank the front a couple of turns.

My front u-joint was really bad. Like it had never been greased in it's life (except the once I did it during my 1 year ownership).

I'm also curious how much (extra) travel the slip joint has for lengthening travel of the driveshaft. (Kinda makes you wonder if lifts are as easy as some posters make it out!)
