2.4 RWD Minibus Wheel bearings

[sidneysausage]

Hi All, Trying to solve the annoying noises on my van. 2009 2.4 RWD Minibus. Seems I have a rear wheel bearing gone and to add to the job the last MOT said the rear discs will need replacing soon. Handy thought I as if you have to take a hub off replacing the discs makes sense. So my question. Where can I get rear hubs with bearings already pressed home? I tried Autodoc and despite having the reg they managed to send me FWD rear hubs, if that makes sense, and then they suggested an alternative which was just the bearings!! Without the use of a press, I'm thinking this isn't much of an alternative. So I've googled and googled and found nowt Is it me or are the hub assemblies hard to find? Any suggestions...pls??

Mk7 2.4 RWD has full floating rear axle/hubs. The rotors are actually bolted to the hub assembly, ABS reluctor rings need to come off, they're just pressed onto the rotor. The bearings are a pair of tapered roller bearings on each side with the outer races pressed into the hubs. They have a 65mm nut holding the hub to the axle housing, left side is left hand thread and they're done up to a silly torque, you'll need at least a 3/4" drive 3' knuckle bar with a 4' pipe extension to remove them. You'll definitely break a 1/2" drive knuckle bar. Hub seals will need replacing as they tend to leak if disturbed.

The bearings rarely fail as they use the diff oil for lube.

So I've looked into the maintenance history of the van and the rear discs were changed a year or so ago, so would I be right in thinking the "mechanic" may not have torqued the hub nut to the "silly torque" required and this has caused the bearing to fail? The driver's side definitely gives the classic wopwop sound. Guess I'll have to buy new bearings and pay to have them pressed into the hub??

Anything is possible I guess...The bearing/hub retaining nuts are done up to 425nm (314lb-ft)...so yes, they need to be tight.

If it is indeed the bearings failing, yes, the outer races will need removing from the hub and new ones pressed into the hub.

Thanks for your help, much appreciated.

There is access to the races to knock them out of the hub with a drift, they are a simple 'spaced pair' assembly, so easy enough to do yourself.
