Vehicle:
2000 XJ, 6cyl, Auto, 231 w/SYE. Frt HP D30 w/Trutrac,
Rr 8.25 w/Powertrax, 4:11 gears, 5" hybrid OME lift w/OME shocks.
BFG 31 AT's
Problem:
Slight vibration above 50mph, but loud drone above 70mph. The drone is low frequency that
ocilates every 2-3 seconds. The original LP D30 and 3:55 gears had same condition, just at different
speeds of course. Drone is in the rear.
Treatment to date:
Removed front then rear shafts. Front had no effect,
noise is all but gone when the rear shaft is removed (rear is the
problem). Have installed (2) Tom Woods and (1) stock front shaft
mounted in the rear. The front shaft installed in the rear is the best
(Sorry Tom)? Swaped 2 then 4 degree rear shims along with longer
shackles. No real effect other than tone.
Possibles:
Having eliminated the front end I am working at the back. I am
now looking at the yokes and the SYE rear shaft. I am the original
owner and the rear axle yoke has not taken any hits. I have a
BayouGeep SYE setup that looks and installs like any heavy duty
replacement rear shaft kit. The TC yoke was new in the kit.
Help?? Anyone have a yoke that was out of round from the factory?
Thanks
