Rear hub bearings-grinding noise- Going crazy!!
Hi everyone my name is Steve and I have a 1992 LS400. I recently replace both bearings on the rear hubs. I did this because I was hearing a grinding noise coming from the drivers side and decided it would be smart to do both sides. I knew it wasn't my pads because they are almost brand new. I knew this was going to be a big job so after 10 days of hell I got it all back together. I broke both trailing arms and had to grind the old ones off because the bolts were fused in the sleeves. The biggest thing was figuring out how to keep the upper ball joint from turning but after searching online I found a solution. Okay so now it's all back together with brand new bearings pressed in by NAPA and the axles barely turn and I'm hearing an awful grinding noise. I thought the axle nut was too tight but loosening it didn't help. So my question is what the heck is causing the axles not to turn freely? My traction control light/check engine light has been on almost a year but I kept driving the car because I didn't notice anything out of the ordinary. Any help would be greatly appreciated thanks

you sure the bearings are to blame? when was the last time you replaced your rear diff fluid? it might be a good idea to see its condition.
grinding would lead me to the differential or the axles themselves.

How many miles on it? I don't think anyone has had rear bearing problems even way past the 300,000 mile point. I agree with timmyotool. But also now since there are new bearings and who knows if they have been pressed in correctly and weren't damaged in the process, or if they were bad before the install.
So did Napa say the old ones that were removed were bad?

Can you grab the tires when the jacked up and wiggle them in any direction? And when you turn them with out axles connected they turned very quietly? Now check the front bearings. How do all the abs reluctors (tone ring) look, any wear?

Yes as I said the axles turn freely in the hub without being connected to the differential. There is a little wear on the tone rings but it doesn't look that much different than the new axles.

There should be zero wear on them. Nothing is supposed to touch them, and that could be the noise. They are kind of like the crank sensor there is supposed to be an air gap to the ABS sensor from the tone ring, if its touching that is not good.
Tires turn we got that................. now jack up and grab top and bottom of tire and push in and pull out alternately, is there any wiggle? Figure out why the reluctors have wear, that could be your grinding noise.
Another item to check is the drive line center bearing.

you're sure it's not the shoes rubbing on the inside of the drums? could've gotten misadjusted when you have everything apart. can't tell from your posts if the noise is there without the rotors on.
also curious about wear on the tone rings... especially if you have ABS error codes..

Do I need new hubs?

Since the shield is so bent up and not sure if that seal is correctly seated or not, you have found the problem.
New hubs? Why are they bad? Maybe everything just needs to be installed correctly and bent metal straightened up. You don't want metal chips in areas where grease is lubricating. Sure looks like gouge in that area above the sensor.
