Wheel Bearing

[French G.]

Sounds like sometime in this car's checkered past that rear corner got whacked and the stationary assembly aligns the tire with something other than straight forward, putting load on the bearing.

Do you have any pics of the failed parts?
What kind of wear pattern do the failed bearings have?
What kind of wear pattern do the failed bearing housings have?
Pics are a +
Are all suspension components straight/undamaged?
Are all suspension components secured with good bolts and torques and good bushings?
Are the suspension mounting positions in spec (frame alignment)?
(Frame straightness can shift over time, even in non accident cars)
I think its a MacPherson strut in the rear, right? -- Is the strut in good shape (all the above questions)?
Is the damping rate of the strut still in spec?
Is the spring rate and unsprung spring length in spec? Are you missing any suspension ride height shims?

You said there is more inside edge wear of tire; that would indicate too much camber. Has a previous owner changed the suspension for drifting or autoX?

Is there any other tire wear? Or do you have tire wear pics?

Have you measured the run-out of your tire diameter?
(Tires are notorious for having out of spec run out.)

Are the rims straight?

Was the suspension aligned by a reputable shop after every bearing hub replacement?

Have you measured the toe?
(I'm thinking this could create a side load in the bearing.)

Have the rims lost any balancing weights?
Whens the last time the tire and rim have been balanced?

I've replaced the part.  Here are pics of the old one:







The bearing surfaces appear to be alright.  Suspension inspection didn't yield any obvious problems.  Some of the rubber bushings are a bit oxidized, but nothing too bad.

Perhaps I'll take it to a tire shop - see what they have to say.

(Made In China). Try to find a wheel bearing that ISN'T made in China.

Unless it is just the lighting, the 3rd photo seems to show some slight discoloration on the race. A straw color. This would indicate heat, possibly from running too tight. Also appears to either have grease streaks or the beginning signs of brinneling.

Even with a unitized bearing assembly, one meant to be torqued into place, there should be a slight amount of axial play in the assembled wheel hub. Approximately .001-.003".
