just replaced two.
I used the bearing carrier mounting holes and 4 M12 bolts and jack down on the back of the hub so it jacked the bearing off the hub. Because both of mine we're fecked. It left a bearing shell on the hub shaft. No problem if you have angle grinder and 1mm cutting disk. cut the shell at a 45 degrees angle from top to bottom, be careful to watch your cutting depth. Then with a chisel,I got a piece to fracture off, this caused the bearing shell to become loose on the hub shaft and with a gentle tap was able to push the shell up and off the hub shaft.
Getting the new bearing on, put the hub in the freezer and leave for some time. The bearing in a very warm place, not to hot where it would melt plastic or boil off the grease.
To get the bearing back on, I manufactured a device, as seen below. One plate on the top of the bearing, with the bolt going through the centre of the shaft and bearing and the other plate on the hub side.
Using a battery impact gun, just jack down, bringing the two plates together and such squeezing the bearing onto the hub shaft.
you can see on the left hand hub , marks where I jacked down against, using the hub carrier mounting holes and 4 bolts. I'm not bothered about the marks as you won't see them.
......or and probably easier, find a local garage with a press
