Rear wheel bearing - just checking before I start

Hello,

I'm pretty sure one of my rear wheel bearings needs replacing - I’ve checked that the new humming noise is not the brake pads being worn down to the rivets, and during the inspection - whipped of the cover to the bearing and noted a small amount of rust inside the plate cover and bearing housing. upon replacing the wheel - I span the wheel by hand as fast as I could and heard a rumble noise - conclusion - rear wheel bearing for sure ???

I've replaced bearings before - on pre 80's cars, but without a Hynes I’m a little worried to start this job - with out checking here.

In the past - Id whip off the cap , clean out the grease, remove the split pin from a castellated nut, undo the nut, prize out the bearing, grease and fit new bearing using <b>feeler gauges</b> during tightening = to ensure the correct tightness.

What can expect with this job (on the audi),,, will I need anything more than a 30mm socket and torque wrench, how will I know how tight to tighten them. and also is there some ABS sensor or something that I need to look out for?

( I’ve tried search here for help about this job but alas couldn’t find anything that answered all my concerns) :eek:)

Any help and advice welcome

Cheers
Jon

Every time I have taken the hub off it has just slid off really easily. Why not just do a dry run to check?
The dust cover just chisels off with a screw driver.
You can get a whole new hub for about £15 on e bay so worth considering doing if it is a bit rough or sloppy or whiny

Hello, i have a question about torquing the rear wheel bearing, here is the description:

I've been replacing rear parking brake cables, no need to remove the hubs but i've noticed they were significantly tight, just like i could feel the balls skipping. I thought its a rust buildup on ABS rings, so i removed the hubs and cleaned everything.

But after i've installed them according to the procedure, 70Nm +30deg they were too tight like before. So i've tried again, even with rotating the hub while torquing and the same result. The hubs actually are not that old, looks like previous owner has replaced them not a long time ago.

But, when i only torque then first step 70Nm, they rotate ok, no play, no drag. But when i go further they become way too tight IMO.
So for now, i've bought new locknuts, and i'm planning to just torque them by feel, and not any further.

Whats your opinion, if i may ask, has anyone came across such case.
