High speed vibe at 60mph...

Achmed · Apr 7, 2009

For the longest, my XJ has always ridden like a Cadillac, but now, at 60mph on the button, I seem to have a high speed vibe under even the slightest load. When I let off the throttle at 60mph, it is smooth as a babies butt. Again, only at 60mph. Opinions? Rear shaft has a new u-joint. My senses tell me the centering ball on the CV shaft, but what say you?

2000 XJ

Stock shaft

tcase output bearing?

im confused by stock shaft, stock slip yoke but has a cv joint welded to shaft.

so you replaced the transfercase end u-joint and slip yoke with a cv joint with the slip yoke on the end of the cv joint?

is there any play in the cv joint? save you checked for wear on the splines of the out put shaft? are you getting any spring wrap when under load?

Pinion or carrier bearings?

It may be shim related because I jsut replaced the aluminum shims with steel shims and it was about that time that I got the vibes.

You should just do away with your whole home brew setup. Buy a real SYE and CV joint after market DS. But like the last poster said check to see if there is any play in current CV joint/ball. That would be my guess.

have you checked/retorqued the u-bolts?

Achmed · Apr 7, 2009

Yes, re-torqued them last week. Update: just removed rear DS and it is smooth. Gonna have the shaft checked/balanced and go from there.

I have wheeled it hard for a year like this with ZERO issues.
