I have a 90 XJ, 4.0 AX-15, D44 rear.
The rear has been completely rebuilt, I'm running 4.10's and there's an Aussie Locker in there.
I recently switched back to a stock muffler and the other day I was on the highway and I thought I heard a low jet but the noise was coming from the rear end.
The noise only happens when I'm in gear and barely on the gas, not accelerating nor decelerating but just giving it enough gas to have no effect on speed. Sometimes it's louder than others, it ranges from a hum to a scream.
I opened up the diff, everything looked good.
Any ideas here folks?
