2001 XJ 4x4, 151k miles, 100% stock. I have a very distinctive loud roar. I think have enough info for someone here to help diagnose:
Roar is present when:
- Decelerating in a straight line or corning left (loudest at 40-mph or under)
- Left turns in curves (at speeds 10-mph or above)
- Pretty much anytime I take my foot off the accelerator
Roar is NOT present at all when:
- Accelerating (at any speed)
- Right hand curves (completely goes way when I bank right, at all speeds)
- In neutral. If I slip tranny into neutral while the roar is present, it completely goes away, at all speeds and all conditions.
Hopefully that is enough for someone to help. The roar is loud, it takes over the cabin and I can't even hardly hear the radio. But pop in neutral and it all goes away. Put the foot into the gas, and it all goes away.
Iv'e wiggled the drive shaft at both ends and do not feel any play. I checked my rear diff fluid, and it was full. To me the sound seems to be coming from the rear, but I know it can be deceiving. I also pulled rear brake drums, and shoes are fine, nothing broken. Tomorrow I plan to check the transfer case fluid.
Thanks for any help guys!
