I've got a noise that definitely doesn't sound good when I'm cruising and then let off the gas. It usually takes a split second or sometimes a couple seconds before I hear the sound and feel the vibrations. It sounds like something in the driveline, axle or maybe wheel. The sound is kind of a growling sound and a bit of a metal on metal rumble. It lasts for a another second or two and then stops. I also feel some vibes when going up a hill and giving it gas.
The XJ was recently in a shop and they repaired the front left wheel bearing that was putting out even worse sounds and vibes. They installed new pinion and carrier bearings in the front. They also rebuilt the rear axle.
I installed a 3" lift and 32" tires prior to the above work being done. However, I did notice the noise when letting off the gas prior to the lift install.
My gas mileage has dropped probably a 15-20% recently. Not sure if this is strictly due to the lift, tires and steel bumpers (front/back) or if the problem behind the rumble noise is a factor as well.
I'm hoping that this scenario sounds familiar to someone and can help diagnose the issue.
The shop I took it to said it might have to do with the transfer case. Any other thoughts? They didn't try that first though, so I'm not certain that's it.
