Default Wheel Bearing going bad?

Well, I started off with volk gtns and switched to volk gtvs, when the gtvs were put on there were aluminum hubcentric rings and I left them on for the gtvs - no problem.I recently got some te37s and the aluminum rings are kinda corroded onto my hubs so I left them there.Now I have a horrible noise at slow speed, coming to stop, under 20 mph it starts - under 10 mph its really bad. It sounds like when your brakes go bad, I got it checked out by my mechanic and my brakes are fine, all my bearings,etc look fine.He thought maybe the backing plate behind the rotor -but no- it is still making noise.
EDIT- It only starts to make noise after ive been driving a while and the car is warmed up.And it started about a week after I had put the te37s on.

SO

I think its the hubcentric rings...

???



Thanks

Took it to my buddy at discount tire and he said the hubcentric rings are fine, the wheel mounts up perfectly and he thinks the aluminum rings I have are better than plastic ones.Thats a personal preferenc I guess.
I guess I'll be taking it back to my mechanic and maybe check out the wheel bearings.

It only makes this noise after I have been driving a while.
Sound like only the fronts make noise.
I still dont know what it is!!

Well my hubcentric rings are fine, my wheels mount correctly.

I just got new front rotors/pads.My mechanic noticed my brakes pulsed and my rotors were a little warped.
This didnt fix my problem either.

I can hear a metal noise, jsut my passenger front side.
I can hear it a lot at 20mph and less.
Very noticeable once my car is warmed up.
I can hear it at freeway speeds as well.
I drove near a wall and can hear a spueak-squeak-squeak nosie on the pass side
when I drive against a wall I can hear it from my pass side and not drivers side, this is at 65mph.

All Im thinking is wheel bearing,same with my mechanic he said if the brakes didnt fix the problem it must be the whel bearing..
I should replace both wheel bearings?
Not just one side? since it seems to be my pasenger side.

Any ones help would be greatly appreciated.

Believe it or not, it may be coming from the back. Seen this quite a few times.

First, make sure the tin backing plates are not touching the rotors.

Next, do the rear axle nut tsb. Remove the rear axle nuts, grease the face of the nut, WD-40 the threads of the nut, and torque them to 220.

Report back.

I will get the rear axle nuts looked at monday.
My mechanic initially thought the backing plate but he bent em back a little and its not them.Although I will check the rear ones, we only checked fronts.
At first i thought it was coming from both front sides, then I drove it near a wall and can only hear it from passenger side, It sounds like the front but hey with all the research I have done on here and your advice, it probly is the rear.
Will report back monday.
thanks again.

You were right, its coming from the rear. The passenger side rear.

We noticed the hardware on the rear caliper had some marking on it and there was marking on the brake pad that hardware touches, we lubed up the hardware, put it all together and the noise is still there, just as bad.It definitely gets worse as the car warms up.My mechanic is really good, as he is ETHICAL and KNOWLEDGABLE, very hard to find these days, Its not like Im taking the car to Midas or some rip off place, I know this guy pretty well. He wont have time to really get into it till tomorrow (Tuesday) so I will keep you posted tomorrow.

With the car jacked up, when you rotate the passenger rear wheel, you can hear the scraping noise ever so slightly.So its definitely that one side. Im really thinking wheel bearing, but we'll see tomorrow when everything is apart. He didnt seem to think that the axle nuts would be the problem. The noise is pretty severe.
All I can think of is I ran over some 2 x 4 s on the freeway, but that was with a different set of rims and this noise started probly 500 miles after that.
Im trying to give you as much detail as possible.
I'll keep you posted.
Thanks

If the axle nut is left unattended for too long, the inner races of the bearing will shift around and wear out the hub, loosing the press fit. From there, it will ruin the bearing.

Print this and give it to the guy. Not that he doesn't know what he's doing, just that this is something I have dealt with on the s2k over a dozen times.

Rotation noise/scraping noise is very typical of the axle nut issue.

Well the rear pass side bearing was toast!! The new bearing seemed to go on to the hub too easily but I couldnt get a new hub so I had the new bearing pressed onto the old hub and I still hear the same noise!!!
Its not as noisy as it was but its basically still the same.
The drivers side hub/bearing seemed to spin freely so we didnt bother with changing that side.
Torqued both axle nuts to 220. I think they were already at 220 because when we went to torque the drivers side it was already at 220 and when he put together the pass side he torqued that to 220.
Oh yeah the only bearing I could get locally was $160!!!
Hardtopguy's bearing price is $57!!!!
So yeah , Im trying to get a hold of Jeff @ Hardtopguy right now to order the new hubs & bearings.
Thanks for your help Billman, and let me know what you think.

I think you're going to ruin the new bearing in about a week. Both inner races of the bearing must be press fit to the hub.

The other side is not 220. Just because you had the wrench set at 220, and it clicked off without moving the nut, does not mean it's torqued properly.

I though your guy was the shiznizzle

The only way to do it right is to follow my original directions above. As of now, you're on your way to destroying the new bearing, the good one on the other side, along with the good hub.

I know that new bearing is a waste of money because the hub its on is no good.
I will go back tomorrow and have him tighten the good side correctly, as you said.
See if that helps at all.
Im going to order new hubs and new bearings for both sides, cant get a hold of Jeff today.If I can place the order through you let me know so i can them asap.
Thanks again
