Am in the process of replacing both front wheel bearings. Have done the r.h. and have the l.h. stripped ready to press the bearing out on Monday when I go to work. You need access to a Hydraulic press at least 25 ton capacity, ours at work is 30 ton and just managed to pop the old bearing out. Hard part is getting the hub off the swivel they get rusted on and it's a hammer and big chisel job to break the joint then dress it up afterwards and put pleanty of copper grease on prior to assembly.Luckily, I had mine off about 2 years ago to do the axle end oil seals so this time they were not too hard to remove.It may seem butchery, but there is no other way you can break them. Forget WD40 & Plus Gas, it's muscle I'm afraid that shifts them.
