Tools Reqd for Wheel Bearings

[MudRunnerTD]

Yep, tools as Winnie said:
I just re did mine. This is for a GQ
You'll need an allen key for the 6 allen head bolts.
Get yourself a set of multi circlip pliers to remove the circlip off the end of the axle.
To remove the inner cover, just grab it with a rag. It slides off pretty easy.
54mm socket to remove the nuts.
A spare lock washer wouldn't go astray, or at least a hammer to hammer it flat to reuse it. But always good to have a spare in case it's been used a few too many times.
Torque Wrench that goes up to at least 170Nm
Flat blade screwdriver to bend the lock washer. I actually use a bicycle tyre iron. Less chance of doing any damage when bending the washer.

You really only need to try and get the 170mn of torque on brand new bearings and only to bed them in for a couple of spins. you then need to back them off to basically finger tight. On the GQ Lock nut the Lock nut locks down on the bearing nut but the pressure on the Bearing nut is finger tight. The GU upgrade this is not required as the locking screws do the work of locking the rounds nuts together.
