Hi... Just been having a bit of a look after hearing a noise from the rear brakes but I think it's from the diff.. after jacking it up and giving things a good move about, there seem to be a lot of movement in the rear wheels, top to bottom as if you was checking a wheel bearing.. but the movement is at the diff end??.. it's on both sides but the drivers side is a little worse. Is this normal??.. or will I be getting the toolkit out??... Thanks in advance for any help!!... Andy..
