Volvo Repair: 740 wheel hub replacement, wheel bearings, wheel hub

Question
I own a 1990 740 volvo sedan.It has nearly 180,000 miles and the front rotors have never been replaced.  I noticed that last time I changed the brake pads,the rotors where pretty worn.  More recently I began noticing a noise coming from the front wheels primarily when I was turning.  I assumed this was probably wheel bearings.  I intend on replacing both the rotator and the bearings.  Then I find out I will need to replace the whole hub.  I have no problem removing the calipers, the rotator and the Hub, but can you advise on the steps for replacing the hub (i.e. type of grease and torque specs for the center nut.

Answer
the hub has sealed bearings and will not need grease.I am not sure if it is 65 or 85 ft lbs.it usually says on the cap covering the hub nut.to replace just remove the hub nut cover and remove the hub.to install new hub you need to use a large socket or piece of pipe that will push the hub on by the bearing otherwise the bearing will come apart.I would need to look at work for torque spec.
