I have problem with the spindles on my '92 F150. They are rusted on VERY bad and i cant get them off. I'm not sure if I should hit it with a rubber mallet or what. What should I do??I need to take them off in order to replace the ball joints. Any tips on doing that too?

 

well they make a tool to remove spindles, but the way i've always done it is get a punch and a big hammer, from the back side theres some holes you can get to to pound the crap out of them. It usually works after a six pack and a half hour.

 

Letting them soak in penetrating lube may help a little. Along with what Ryan50hrl said, you can also give them a good buncha wacks with the rubber mallet like you mentioned. You can also use a block of wood with a big hammer. The wood is soft enough not to damage the spindle. Yet another option is to use a cold chisel to "wedge" the spindle off. Be careful using this method though.

You have to get it off the studs evenly or it will bind itself on.

 

once you get them off the first time,,,,,subsequent times are much easier.

 

I got them off. I let them sit in 3 diff. kiinds of rust busters and had to chisel them off. Now i have to get the ball joint nuts off.
