Now that you have made sure everything is clean slide the axle back in BUT DO NOT REST THE AXLE ON THE SEAL THAT YOU JUST INSTALLED INTO THE HOUSING as you slide the axle into position rotate it as you push & try to lift the slpined end up as you push it in so it will slide into the planetary then tighten all the nuts up & refit the disc & caliper
When doing this repair just take your time & think ahead theres no rush & remember its easier to fix a stupid question than it is to fix a stupid mistake
Any questions just ask
My next job hopefully will be to rebuild a 5speed & transfer box & replace a 5th gear shaft
