Just looking at changing my rear wheel bearings (ABS fault) and I'm struggling to find consistent torque values for the large centre nut and also looking for confimation on tool required for this and the brake caliper retaining braket.

 

I've seen torque values for the centre nut between 127 & 180nm plus a 180° turn.  I suspect true value is 180nm and the 127 although quoted in nm is actually a ft-lb equivalent but would apprecitate confirmation.

 

The tool required is a spline/torx type, I suspect 18mm XZN but again would appreciate confimation (as I'll have to buy one) likewise for the caliper braket which I belive is XZN 14?

 

All help very much appreciated.

FWD or 4x4?

Cheers Chimaera, it's FWD

Service manual says 180 Nm + 180 deg. No indication of what tool is needed to tighten it nor the caliper bracket screws.

Cheers again Chimaera. 

The 180Nm is not so bad but that 180° had my 3/4metre, 1/2" drive breaker bar was bent like a nine bob note!  No lasting damage though.

 

Just for any one else looking the tool is a 18mm spline tool seem to also be called XZN splines.  It is NOT Torx.

Also need a 14mm for the brake caliper mount screws which VW have carefully designe to be as difficult as possible to get on to, would have been easier to hake the whole rear corner off it I'd had it on the ramp.  Best advice it to get the shortest spline tool you can even the short one I had was difficult.

 

Annoying thing is the bearing felt perfect, should be as the car's only done 120,000 miles but the problem was the ABS trigger ring.  Sorted it and I'll be doing the other side soon as I can, there's no problem with it but my OCD won't let me change one side.

When I done mine because of the same reason.

The hub bolt was no where near as tight as the required torque when undoing it.

Torqued to 180nm but couldn’t get the 180 degrees but it was tight.

Yes the carrier bolts are a pig, I manage with a wobble drive extension and flex head ratchet 

Also now use a 14mm spanner on the M14 spline

That's just the kind of tool I wish I'd had today and yesterday.  Don't know why the hell VW don't use hex headed bolts given the access issues. 

Actually I do know why!

This is the one I have
