Wondering if anyone can help as i've got what is becoming a very expensive and tiresome problem relating to worn Front Wheel Bearings on my Omega 2.2 CD Auto on a 03 plate.

Since May 2007, 54,000 miles, i've had to replace worn FOS Wheel Bearing 4 times & worn FNS Wheel Bearing twice, I know it's unheard of, or so everybody tells me.

FOS is now making the sound that it has gone again, 76,000 miles (By now I know what a worn wheel bearing sounds like).

The 1st one going, coincided with an electrical gremlin back in May 2007, but was not identified / rectified, but seemed to go away.

Any help and advice would be appreciated as the wallet can't take any more.

Thanks

Something wrong here, is it overtightened? Wrong bearings? Shoddy parts?

When you`ve replaced the bearings have you torqued the hub nut to 320nm :question

The first couple of replacements were done by Vauxhall Main Dealer as car relatively new so would hope that correct parts and tightening was done properly.

Since then local small garage done work who suggested that it may be build up of static (apparently similar problems on Peugeots) They installed earthing cable in an attemp to discharge potential static on FNS.

static? Wtf?.....old wives tale i would think.

These failures. Are we talking actually failed bearings or just a bit of play? Which can be taken out by nipping up the end bolt. Failures, with genuine parts fitted by vx. I would be back there banging the desk tbh. Politely of course. :-)

Have had a hub from first line with maltezers for bearings. But never an issue with vx ones.

Are you aware the bearings are pressed into the hub? So vx will presumably be fitting the whole hub, rather than just the bearing itself ?

Just a thought....

Could a machining fault on the stub axle have caused failure of all the bearings fitted to it ?

I would be tempted to get a good second hand front hub or front strut assembly from one of the people breaking cars on OOF.

My last Omega still had original wheel bearings after 200,000 miles so I wouldn't have any worries about second hand.

I understood that the wheel bearings were non-adjustable on Omegas. Held in place by a single nut done up so tight (320Nm) that you need a 3 foot breaker bar to shift it.

Thanks guys for all the help and advice.

Apparently the Wheel Bearings assembly come as a complete sealed unit and this is what was replaced and charged for!

Will take on board ideas on the tightening of the hub nut to 320 nm first before the current FOS gets replaced.

Question......is the dust cap in place over the hub nut?

A good bearing will last the life of the car, they are not a weak point and certainly static is not an issues here (although I can just about get my head around how discharges within the bearing could spark errode the metal running surfaces).

I have used Contitech ones in the past from www.buypartsby.co.uk and they have been excellent quality (and around 35 quid)

Took some play out of mine by tightening it very slightly, and yes your right, you will need a 3ft breaker bar, and a gorilla. I only had a cheap 2ft breaker bar and it very nearly snapped it half. But no more excessive play in the bearing.
