Getting pins out can be as easy as tapping them out or as hard heating the axle red hot and using a pin press. You can never tell if one side will almost fall out and the other never comes out. Your best bet is remove the axle and bring it to a good automotive machine shop.
Completely agree
Did mine like this.
1- Removed the Axle
2- Had it sandblasted (didn't care about rust... I painted with Por-15)
3- Took to NAPA (They pressed out the old pins & installed new bushings in the knuckles)
4- Painted
5- Installed new kingpins and keeper pins (Be aware that the keeper pins are made to go in only one way. Made this mistake and tried to force them... That wasn't fun)
NAPA ordered the kingpin set... The set plus labor cost around 120 bucks (Pin set was $90 if i remember right, making labor $30)
