TJ rear diff noise

[Bodil40]

Is the stock rear differential pretty noisy in these Jeep tjs? Or is it just cause mines low miles and still breaking in. When I drive in a low gear(high torque) scenario the rear diff seems to like whine, is it just a Jeep thing or should I look into it?

Is it your diff or your transfer case? My nv241 is pretty noisy in 4lo.

The noise comes from the diff and happens in even 2high

Dana 35 I'm assuming. I'd crack it open, drain the gear oil and take a look at the ring and pinion gears. It sounds like you may have broken a tooth. I had a couple of broken teeth on one of mine and it caused a whine and some vibrations. You'll want to set the axle on jack stands so you can turn the tires and check all the teeth, those in the back, especially on the pinion, will be hard to see, but you'll probably know from the gear fluid if you broke a tooth. Won't hurt to change the gear oil if you haven't in 30,000 miles.

The 35 and 44 are quiet diffs. There should be no noise unless there are issues. Pull the cover and see what the fluid looks like.
