Rear end noise when turning right.

[jaycommando]

Evening all,

I'm getting some rear end noise when turning right. Kind of a whine or grind. It reduces or disappears when I straighten out or turn left.

It's obvious when doing a swooping s turn.

I had the diff rebuilt in January and the front hubs were new last year.

My reading online leads me to think it's a rear axle bearing. But I'm looking for some reassurance.

What's your thoughts on the cause? Breaks aren't sticking and the truck runs and coasts fine.

Check your left front , maybe the half shaft

That is a wild guess on my part

Not enough friction modifier in the diff oil?

I’m a bit surprised the shop didn’t replace the axle bearings when they were in there. If I pull a differential apart, I’m not putting it back together with axle bearings with that many miles on them.

I think you need to just approach it as a fresh problem and diagnose all the possible causes. Considering the lousy state of manufacturing and supply, there’s every chance a new bearing put in recently is noisy.
