Noise from right rear
 

I was all good and ready to change all the u joints. Even after reading the wheel bearing threads. UNTIL....... there was this grinding sound comming from the right rear. Hmmmmm.
So now i am firmly in the wheel bearing camp.
Does anyone have a link to these teflon washers?
Also, is there a preferred wheel bearing and supplier?
Thanks everyone!

The washers are hard to find. GMPartsGiant stopped carrying them, that's where I got mine from. I went with Timken bearings from rockauto.com, they went on easy, and allegedly hold up well. I'm at 10k miles on mine, and no issues thus far. One evidence of their build quality is that mine still haven't rusted. When I did a Chinese hub on another car, it was coated in rust by the next tire rotation.

Try Corvette Central IIRC. They were able to get some in not that long ago. Based on the appearance, they look to be clones, but something is better than nothing.

Good luck.

Guess it makes sence to replace both rear bearings at the same time as the other side cant be too far behind.

I did all four since I was chasing a noise that would come from under the car when any wheel hit a bump. They were original with 130k miles, and three of them had lost their seal. The rears are a little iffy to get off, make sure you have a good T55 Torx bit.

This is old school, lift the left wheel off the ground and the car in neutral. Place your hands at 12 and 6 and try wiggling the wheel up and down. If the wheel moves it is usually the wheel bearing. With the hand at 3 and 9 you can also check the tie rod ends for play. We do this for tech inspection at autocross and HPDE events as part of the inspection process.

Here is a link to the washer. https://www.corvettecentral.com/c4-8...r-inner-584093
I simply reused mine.

I was getting the clickity clicks. First from the right side and a couple months after I swapped that one, the left side started. I bought cheapo Amazon ones and lathered on the anti-seize on the stubs. No more sounds and the car handles much better at speed.
