Hi all, Iv just replaced the wheels bearings on the front of the willams and need to know the correct torque setting for the hub nut for the drive shaft, I spoke to the bloke at Renault and he said 25NM this is sooooooo loose a setting so im thinking he has got it wrong?? :roll:

i just get the breaker bar on it and do it up 'guess tight' also known as murder tight ;-) never had an issue with it coming undone

Well I dont want to kill the wheel brearing again as I done it real tight last month and didnt bother with torque settings and its killed the new brearing within a month! Im getting board with taking these bloody hubs off now lol :lol:

250 for Nyloc type nut.
281 for self locling nut with integral washer.

As coops said i would just do them as tight as possible with a breaker bar. I usualy use an impact wrench and go at it pretty hardcore. :D

theres no way in a bizzilion (real number) years you can **** it from over tightening, if it goes that quick its either shit bearing or kippered hub.....or the hulk did it up for you :shock:

I've been through three front bearings on the same corner in only a thousand miles or so. So I'm trying a new hub now. The existing one looked fine to me but is there anything with a hub that can cause these failures that isn't visually obvious???

well if its down to a bearing failure, then it would be either misalignment or excessive stress causing failures. Can't see it being a dodgy brearing if it has happened 3 times.

Bearings are pretty high precision manufactured items, and although do have tolerances to cater for assembly mishaps they still need to be fairly accurate to prevent early failure.

I am guessing that the old hub might be oversized, so that the bearing isn't 'pressed' as tightly into it as it could. This might result in the bearing housing moving around slightly.

Have you checked your wheel alignment? This would also put excessive amount of stress onto the bearing if the camber is too much..as the whole suspenion set up and wishbones are bolted onto the hub.

also dont rule out incorrect fitting of the bearing, might of been pressed in badly and the seals broken or something...

tracking is spot on and the three different bearings were all fitted by different garages. But one did mention that the bearing was 'falling out' so maybe the hub was oversize....
