Volvo Repair: front wheel bearings 1988 760 turbo, front wheel bearings, wheel hub

Question
It seems that I need a complete wheel hub and bearing assembly just to replace the bearings on the front wheels. It needs to be ABS but the wheel hub assembly without ABS is far cheaper so is it possible to purchase the non ABS hub and attach the old ABS ring to this? Also feels like the brake rotors are warped, would you advise replacing them or would having them "turned" suffice?

Thanks, any help with this would be greatly appreciated.

Answer
Hi..
   Are you sure that you can't buy bearings for A B S hubs?....I think you should look at some of the after market brands...

Don't mix braking parts that may or maynot work properly.
        
Turn the rotors....if possible...save for yard art otherwise.

                   Good luck,
