Growling noise from the rear when turning slowly to right or left. Sometimes it feels like one of the rear wheels are locked and slips during a sharp slow turn.

Also, when turn the steering wheel during sharp slow turns the wheel makes a load groan sound.
Just bought my jeep, has a bering noise from the rear end when i step on the gas
When i let go on high speeds the jeep wiggles in the back end
Moaning noise at 35 mph or higher.
Only when I have the front drive shaft hooked up does it make a almost grinding sort of noise coming from the front differential. Seems to be a common problem. I replaced front left hub assembly. Problem did not go away. Mechanic verified it was the differential. I did not fix. I sold it for the same price I paid for it 2 years earlier. Haha.
growling noise, not yet repaired
Replaced front differential

New Differential
Growing and noisy differential
Noise from back end of jeep when turning steering wheel to right or left, especially in tight turns. In addition to noise, Jeep also bumps and jerks when turning. Mechanic says it's the rear differential support that is rotted and the ball joint in the middle has play. Recommended replacement of the support, bushings and ball joint that holds up the boomerang shaped differential.
a steady roar until recently. While making a left turn, noise increased sharply. Jacked the car up to get the tires off the ground. spinning the tires slowly, I noticed the tire became very stiff.

It's a howling noise when I let of gas paddle
Replaced bad pinion bearing
