Word of warning checking wheel bearing, I could only feel slop in the bearing at one point of the rotation , I checked it 4 times and found no movement in the rear wheel, but still had a noise coming from the rear of the bike ::010::, on the 5th time I checked it I rotated the rear wheel and checked for movement at each segment until I found it, ??? so the movement in the wheel was only in a small part of the wheels rotation and their was quite a lot of movement , I've never seen that before so I was very concerned that it was a diff problem :'( but much to my relief was just a wheel bearing ::012::
