Hi all
Seeing as I don't have access to a copy of Mr Haynes book of lies, could anybody tell me what is the correct torque setting for the rear wheel bearing hub nut thingy. Also, what size is the nut as I will need to buy a socket to fit it.

It's a 52 plate, 2.2 auto if that matters but I'm assuming the wheel bearing is the same on all models.

As ever, all help is appreciated, thanks in advance

Thanks for that. I had a feeling it would be somewhere around that kind of size. I think I'll take the new nut that comes with the bearing with me when I go to get the socket, just to be sure.

At that torque setting worth buying an impact type so you know it wont crack.only few £,s more but safer

The hub nut is 30mm.
I hop you've thought about how you're going to extract the hub from the bearing, and then remove the bearing from the hub-carrier. The circlip requires some hefty pliers too.

It's not a difficult job with some appropriate tools, but without them you will really struggle. I made my hub extractor, but bought the bearing puller set.

Good point. Luckily for me, I know somebody who has the tools to extract the hub so I don't have to worry about that. and I have several pairs of heavy duty pliers

I ended up taking the swinging arm off and had to use a 6 ton press to fit the new bearing

Really? I put mine in the freeze overnight, and was all set up to get it started with a hammer. One good knock, and it was 3/4 of the way in. I wish I'd hit it harder, and fitted it in one go.

Aside from the back-to-front design, I find the worse part is dealing with the damn circlip!

OK, so, admitted to being in over my head with the idea of changing the bearing and took the car to the garage this morning. After describing the symptoms, his first thought was not the wheel bearing but the diff. Left the car with him so he could have a proper look and he rings me back a couple of hours later. Wheel bearing fine, diff fine. Turns out the problem is the exhaust. On the upper side of the pipe where the centre section and back box meet, there is some serious rot and a couple of fair sized holes plus one of the mounts has come away entirely (big hole where it should be).

As I understand his explanation, it was causing the exhaust to move around and rub against parts of the car its not meant to, hence the weird noises. He's fitted a new exhaust and the car is perfectly fine now, no odd noises and is whisper quiet again. It just goes to show how easy it can be to mis-diagnose something. I was 100% certain the bearing was fubared.
