Just to let you know, I had ordered a pair of Teflon hub washers from Corvette Central a while ago. They were not available at that time but I left the order open. Today I got an email that they had shipped.

That's all the info I have, but passing it along just in case.

I should probably think about ordering some while they're available.

Exactly what I've been doing for my 86. Every couple of months I try and pick up a part or two that I expect I'll need some day (those that won't age out) so when I need them I will have them on hand rather than scramble trying to find something when it fails. Had that happen last year, something failed and went to the parts shelf and grabbed a replacement I'd pre-purchased. That was nice. At least you can have access to them especially those that are being discontinued as we speak.

There are those more knowledgeable than me but AFAIK the main reason is to eliminate friction noise between the axel stub and the hub. Pull the spindle nut then the half-shafts and you'll find them behind the splined portion of the spindle stub where it slides into the hub. I have read where people have stated replacing the Teflon washers has eliminated noise when it hasn't been u-joint related. That's pretty much why when you change U-Joints it's suggested they be changed also (do the job once). If you don't mind the noise I don't know that you'd need to replace them but I don't know if you might introduce extra wear if the Teflon coating is compromised.

2-3 years ago you could get these for about $3 ea IIRC, definitely more expensive now but you take what you can find. GM has discontinued them in the last couple of years, so availability has been sketchy.

I just went to the C-Central website. They're $9 each and have a 60 day lead time.
IF I'm looking at the right part #584093.

The washers came in, here's my visual analysis on them:

The washers came in. I'm going to try and do a visual comparison between what I remember from the oem ones I got from the Chevy parts department and put in 3 years ago vs these from Corvette Central.

The oem's (again based on memory) were very even is size, rolling of the lip on the inside and Teflon coating. The coating was even in color and texture across both sides of the washers. To me it looked like the metal part was formed then it was Teflon coated.

The Corvette Central part appears to have been first coated then either the cutting and rolling were done in a single operation or the washers were cut and coated then the bevel put on the inside edge. You can see what appears to be some damage to the Teflon coating in the area where the dies were used to form the rolled edge on the inside of the washer. I think had the dies been used to roll that angle prior to the Teflon coating on these, the Teflon coating would have been uniform across the washer just like the originals were. I figure when I have the need to use them, I'll grease the heck out of them first just to be safe. One last thing, I'm not sure if the Teflon on these is as thick as on the oem's.

I tried to take a picture of them but I don't know it shows up that well.
They're going on the parts shelf for now, about all I can say on them.
