There are 2 seals on the in-board side (one on the spindle, one on the axle) didn't change them because I didn't have at the time but might be worth doing as it will keep the dirt out. Also have new spacers (2 thicknesses available) so that once you're done you can set the thrust clearance to spec.
0.075-0.690 mm (0.0030-0.0272 in), 2 spacers are available 1.80mm & 2.25mm. New lock rings are a good plan too.
