How do I replace the axle seal on the side of.

Undo the drive shaft nut, this will be extremely tight, wheel off, tie rod end off, lower strut undone, swing strut away and pull drive shaft from hub, on the transmission end, the shaft is secured with a roll pin that must be driven out with a pin punch, then you can remove the shaft to access the seal, lever out seal and carefully tap in new seal and lube seal lip with light grease.
