When my rears went bad, the only noise was that "typical" high pitched metal-on-metal sound and by the time I got to replacing the bearings it was making that noise pretty constantly. Your description doesn't sound like bearings to me.
When mine went bad (on both Supras), it started with the tiniest bit of play when shaking the rear wheel (off the ground). By the time the parts arrived, it had progressed into an obvious and consistent grinding noise. It didn't take long at all to get really bad.Anyone have a wheel bearing go bad with no play in the wheel?
Yes, it is loudest when on a slight curve, and on a smooth road. Everything is pointing towards a wheel bearing, except for having no play in the wheels. I got 3 more probes I can hook up to other things."The noise is a humming or gear type sound that changes with steering wheel position"
Do you mean as you're driving down the road and move the steering wheel slightly left and right the noise changes?
That sounds exactly like my 4Runner sounded when it had a front wheel bearing going bad.Yes, it is loudest when on a slight curve, and on a smooth road.
If its whining while deceleration, then the pinion depth is likely off. Did the over compress the crush sleeve?I took a couple more drives with the chassis ears connected. Those things are really slick, and only $100. All wheel bearings and the trans checks out. The noise is coming from the pumpkin I just had rebuilt with new bearings and seals, which the rebuild made no change in the sound I had all along.
The mechanic said everything looked fine inside - including the ring and pinion. It obviously is not fine - it pretty much has to be the ring and pinion, caused by the damage to the original Torsen diff and driving it damaged for 100 miles. The original mechanic who rebuilt it 13 yrs ago told me I might always have a little noise because of that, I always did. I relayed the message to the new shop when they took on the job. Sometimes messages just don't get thru.
The pumpkin is pretty loud with the ears, starting at 40 MPH. When I decel, it gets really loud, and when I shift to neutral in that same scenario the sound doesn't change, it holds it till I come to a complete stop. These sounds match 100% the sounds and speeds I've heard when driving the car without the ears.
For comparison, I put the ears on my T-Bird - which also has an IRS rear and Trak-loc. I got what seemed to be normal gear noise - no big change on decel - and I had to turn the volume up much higher to hear it. I will say - differentials make a lot more noise than anything else - lots of gears whirling around in there. You can hear every shift, etc.
