Technical Replacing Rear Wheel Bearing

[LeftyGreg]

My B needs a new rear wheel bearing

Has anybody had experience of replacing these that can give me any tips?

Also, does it need any special tools?

Thanks

From memory it wasn't too bad a job, I followed the instructions in the service manual, part 44 Suspension - Wheels - removing refitting wheel hub when I did the whole rear axle. The one thing to be aware of is that the wheel nuts need a lot of torque, more than most standard torque wrenches will accommodate. Other thing is that the hub nut needs an appropriate sized socket, I can't remember what it was but I can take a look later.
Good luck

Thanks @Wiltshire Chris , just looked at that page and it doesn't look too bad to do, will I need a hub puller, or will it come off quite easily?

There doesn't seem to be any mention of the correct torque

What I need to do now is have a look at the size of the nut to see if I have a socket big enough, get the new Wheel Bearing and do it before I take it back for the garage

It is the only thing that failed on the MOT, so I have 10 days to do it and get it back to them to save another complete MOT

I don't have one so I suspect it gave up easily

280Nm. I'm sure I uploaded all the torque settings here once but I can't find them now.

Just found this guide which you may have already seen:

Rear Bearing replacement (non ABS)

OK first of all this is a guide, it's how I did the Job. If you have the misfortune of damaging your car, I take no responsibility. I take no responsibility for your lack of safety. :) Right park the car on a flat solid surface put it in first...

@Wiltshire Chris, As always, you are so helpful

Part ordered, hopefully here by next weekend then I have a quick job to do

Should be back on the road soon

 

[LeftyGreg]

Part arrived along with torque wrench, so guess what my job is on this sunny Saturday morning

Hopefully done in time for F1 qualifying

 

[LeftyGreg]

All done with plenty of time to spare

the only thing I changed from the guide was that I had a cuppa tea instead of coffee and a ciggie, gave up the figgiest when I had a heart attack in 2021

Back to MOT centre on Monday to get the ticket, then will be putting it up for sale


P.S. 280nm is crazily tight!

 

[Wiltshire Chris]

Good job done. They are tight, I remember having to use a breaker bar extended with a weightlifting bar to undo mine

The MOT should be a shoe-in now. I hope you get a good price for it when you sell, good time to do it with the sun shining!

It's actually very easy. No puller, no special tools ... except .....
The hub nut is 35 mm. And not in the usual tool kit.
The problem is the space: the wall of my standard 35mm socket is too thick. My DIY garage has 1 that is ground down.
As for the torque, I use a good quality 1/2 inch ratchet-drive with a 1 meter piece of steel pipe. Longer is easier

The front bearing nuts are 35mm, the rear one is 32mm

doesnt make it any easier, as when I put the wheel back on to lower it back to the ground and loosen the nuts, I could have done with n extension of about 20mm long!

Definitely, needed a cuppa to get my strength up before finishing

We're into 'easy' at my age. An extra meter of pipe does the trick
