I just had Rugged Ridge SYE installed on the XJ and am using a stock front driveshaft. Still having driveline vibes at indicated 60MPH and higher. Light throttle I'm fine, but if I am pulling a hill or using a good amount of throttle, it's bad to worse. If I drop to indicated 55MPH ... no problem at all.
My suspicion is I am getting a bit of axle wrap, pointing the pinion yoke up too far.
Some Info:
- Springs have 6 Degree Shim
- Pinion Yoke is pointed DIRECTLY at TCase yoke.
- Cardan joint is good (checked it & repacked)
Now, before I had the SYE, I had a 1'' drop and the axle was shimmed to 4 degrees (I stacked a 2 degree shim backwards on top of the 6) and I was ... okay.
After the SYE, I still had slight vibrations at above 65MPH, but nothing major. I got rid of the transfer case drop and shimmed back to 6 degrees. The DC joint is supposed to do all of the work.
My suspicion is that I am getting slight axle wrap at those speeds, causing the pinion to point up too far.
Any thoughts? I may drop the axle and put the -2 degree shims back in when I get a chance.
Thanks in advance!
