wheel bearing

bonjour, today i changed the two rear wheel bearings with a 10 tons press, no problems for that but,
a new driveshaft nut which must be set on 400Nm i think i was on 100 Nw and i can't turn the hub anymore
i went back to 50Nm and can turn the hub by hand ,this on both wheels, so what went wrong? thanks

Are the bearings pressed fully home?

yes Nodge , if not total in you cant put the clip in

How did you fit the hub to the bearing?? If the centre of the bearing is not supported the bearing can be damaged when pulling it in against the ball race.

Wondering what make of bearing

I'm thinking the same about the quality of the bearings.

the make is SKF , the hub down and i pressed the bearing on top of the hub
so the whole bearing was pressed on the hub

SKF are good bearings. How did you fit the rotating part with the wheel studs on ?? It is a tight fit and needs to be pressed in while rear of centre part of bearing is supported. Not put force through bearing itself.

i don't understand what you mean, i got the bearing out with the press and the bearing in with the same press,
i found a youtube and did exactly the same thing , i have done some bearings before and never had a problem, i think 400Nm is a lot, i dont understand why it must be that much

I have the recommended torque as being 395nm so your 400nm is right

How did you fit the rotating part with the wheel studs on ??
the hub with the wheel studs placed on the bottom of the press, the rest with bearing on top and pressed in

The bearing needs to be pressed into the hub carrier and then the rotating part with the wheel studs on needs to be pressed into the centre of the bearing. When doing the second operation the force must not go through the bearing, the centre of the bearing has to be supported.

yes but i did it up side down so no need to support and no harm to the centre of the bearing,

Don't suppose you changed driveshafts? There is an incorrect type with an abs band that could have caused it to bind. I am just thinking of ideas now as I think you did it all ok.

no i havent changed them, i will drive a bit like it is and will check the nuts, at least they don-t make any noise like it was before, so its ok for me, thanks

Don't forget that the nuts need to be staked over when tight.

yes i know , thanks

Just checking as you said you would drive it and then check the nuts. Not possible if staked over and I didn't want your wheels falling off !!

bonjour, after 500km i put on new nuts at 300Nm , for me its ok, thanks for your help
