Help with sound from rear of car

[Phantom_WS6]

I really need some help with some noise from the rear of the car. It has that same sound as if a wheel bearing is bad, but I changed the wheel bearing and it did not fix the problem. Then I changed the axle shaft and again a new wheel bearing, after which it seemed like the sound was gone for a few days and it came back again.

The car is an 01 Camaro, v6 and auto trans.

Could it possibly be a wheel hub assembly? Some other type of bearing?

Please help!

Mine hums above 70 mph. Not sure if your car would have a 2 piece driveshaft but it could be the hanger bearing but more than likely the clearance in the pinion and ring gear is off.

I know of a low 11 second ls1 camaro in town that cuts 1.6 60fts with a 7.5" and 4.10's that is really loud and he hasn't blown the rear end up yet so if your more than likely not going to destroy anything short term.

Personally Id pull the cover off the diff and see if the fluid has anything in it.

I will do that tomorrow, any idea how I can fix those things you mentioned possible? How I can do additional checks?

What about pinion bearing? Does it make a similar sound to wheel bearing?

Yeah its possible a carrier bearing or pinion bearing is out. Car is 11 years old, pretty much anythings possible.

Tires balanced? Pressures are all good?

Guys, I found out that the spider gears are actually all eaten up..so I guess that is the sound, the bearings seem fine.

Bearings would have been easier..

Why do you think easier?

If nothing else, cheaper... spider gears sounds like a new carrier to me.
