Start off by pulling your wheel then knocking off this cap
Straighten out the cotter pin then pull out
Get out your handy 35mm socket that you just had laying around and didn't have to travel to 3 different part stores to get
Pull the cotter pin and nut off the steering . Give the sides of the knuckle a couple good sacks to help loosen things up , mine just came loose sometimes it might require a pickle fork
next put a jack under the ball joint and jack it up a little to relive the pressure and take off the 4 bolts holding it on should just slide off
then you just give the axle a good couple of yanks and it should pull right out . Reassemble
