Can a differential make the same noise as a bad wheel bearing?
My rear axle makes a rhythmic "crunching" whirring noise that changes amplitude with the speed of the car just like a bad wheel bearing.
We replaced the wheel bearings a few weeks ago and in fact there was one that was shot and made an audible noise when we turned it by hand after the axle was out of the car.
We put new bearings on and the noise was still there.
It's even getting more and more prominent.
Could it be the rear end? The noise was there (though hardly audible) after I put the new 3.8:1 in but I thought at the time that I had damaged the wheel bearing while struggling to get one of the axles back in.
The oil level in the differential is correct btw.
So, can a rear end make a noise like a bad wheel bearing?
