Front wheel bearing gone again....!!!!

[andy-w]

A couple of weeks ago i changed the front wheel bearing...all was fine and now i have covered about 200 miles going to and from work and it has gone again!!!

Tomorrow i will mostly be changing the wheel bearing again...!

Check the bearing surfaces, they have a bit of a history of breaking down - you have to be very careful pressing in/out (which may be too late now....)

Was thinking along those lines...i pressed the old ones out on a hydraulic press so there was hardly any hammering...might just have to get a new hub/shaft.

I might wait and get that before taking it apart and finding the shaft is goosed. I cant imagine them being that expensive...

Try a bit of bearing locktite to keep them from spinning. Cheaper than buying new stub axle. When i did one of my rears the new bearing was turning on the axle when i assembled it. Put it back on with locktite. Fingers crossed it will be ok but havent tried it yet.

Bit late now Andy but I've just binned two front hubs one with brand new bearings and the other with perfectly good ones. Enjoy yourself today

Doh not to worry...i have already got one of your old wishbones on my car...!!!

Hows the new one and when are you going to bring it round....jealous as hell.....!!!

Typical - just checked rally design and they have got front offside only for £40...£15 more than just buying the bearing......!!!!

You did not mix up the races and cups by any chance whilst assembling?

IIRC everything came in one packet and they all looked identicle so that could be a possibility....!!!

Trouble is races and cups are matched sets and not to be mixed,as I remember the sierra fronts are 2 same sized bearings so mixing them up is a possibility be careful here when assembling as rapid failure is the result

[andy-w]

yeah they are two matching bearings...could be a possibility.

think i will try and find a new carrier on monday or just order some new bearings...couldnt get them today.

Sorry to bump this back up...!

Does anyone know the correct torque for the wheel bearing....?

http://www.parkersteve.dsl.pipex.com/chimaeraparts... states it should be 229-258 ft lbs 310/350Nm which is a lot of torque to put on taper bearings...surely this will crush them?

[Pushrod-Power]

The running clearance is set as the two inner races meet the nut torque does not affect bearing crush/preload i have 390 to 450 Nm this end.
