Did you ever figure out the problem? I'm very curious and would like to know. Especially if this happens to anyone in the near future. At first, I thought it would be the arms being loose or something. Maybe a drastic geometric change in the suspension under hard cornering?

 

Well, the next day, I had a national champ s2k driver try my car, and he thought it felt okay; said it was looser than a normal autox setup, but nothing unmanageable. I'm more inclined to go with the second opinion.

The wheel bearing definitely fixed the uncontrollable/massive oversteer We'll never know why that one went bad so quickly...

 

Use a cut off wheel and zip right through the race. Be careful not to cut the hub. Then use an air chisel (or just a regular hammer and chisel) to cut through the last edge. Once its cracked it will slide off no problem.

 

I think I'm hearing the driver's side rear wheel bearing AGAIN. I thought I was imagining it, but I seriously think its coming back; its most noticeable in parking structures (I park in one at work) when I'm making left turns (while going up the parking structure).

I've had this current wheel bearing for two track events (6 sessions total), 1 autocross event, and ~5000 miles of street driving on it.

The oversteer hasn't manifested yet, at least not to a degree where the car is uncontrollable.

What could cause a wheel bearing to bad so quickly? Could worn springs/shocks cause this? What about damaged suspension components?

I do believe that my rear suspension is sagging; my car does have nearly 80k miles on the OEM suspension. Diving duty includes my daily commute, track days, and spirited canyon drives.

 

Did you replace the hub too? I think i remember reading that if the hub is damaged, you'll just keep eating through bearings and they'll keep wearing out.

 

Yup, both bearing and hub were replaced.

I'll be at SoWS this weekend; hopefully it's my brake pads scraping... I really don't want an oversteery car at ACS in 2 weeks.

 

Yeah, it could be, mine are squeeking (brake pads) on the driver's rear side also. You got me worried about my bearings, so I confirmed it was my pads by re-greasing my shims. The squeeking went away, but then it came back (not as bad) after the BW event with ES.

 

+1 to this. The hub gets worn out over time along with the wheel bearing. Therefore, if you don't replace the hub and wheel bearing, the worn hub will have some slop between itself and the wheel bearing and this will accelerate the wear on your bearings. Although two track days is a pretty short time to destroy a wheel bearing again.

EDIT: didn't read the post on the 8th page. Try applying some anti-squeal on your shims.

 

Problem is back.

I'm about to replace the wheel bearing, along with:

- entire rear subframe
- rear arms
- all four springs/shocks

Basically dropping a nuke to attempt to fix this.

Wheel bearing is definitely making noise. This bearing has no reason to have gone bad after about 10 sessions worth of track driving.

 

Mike,

Are you still racing on your BBS's?
