new rear drum cured the rubbing whilst at it I replaced the wheel bearing, when i took the bearing cover and seal shim and front spacer off I could move the halfshaft and bearing still attached to the shaft in and out of the box/ axle casingapprox 4-5 mill, is this normal? got the bearing out and knocked the new one on straight, and re fitted front spacer, shim and o ring and put all back together then no in and out movement from half shaft, torqued up the drums and wheels and have possibly 1-2 mill up and down left to right, is this all ok?
