Rich its a Big job. I don't mine at the end of last year.  You have to take the arms off then wack them in a vice so you can undo the massive torque on the Bearing nut!.   They then have to be pressed out and the New ones pressed in. Its then difficult to Re-torque them as they are so tight. Good job my mate had a 400ft/lbs torque wrench for Trucks!
