Ball joints

[Itsme!]

I have a 99 F-350 dually. 4x4 front abs. i was changin the wheel bearing and noticed the bearing behind that one is out too... I need to take the two ball joints out to get to this bearing. I had no problem with the top one... I just can't figure out how to get the bottom one to crank loose. I'm wondering if there is a special way of takin the bottom one out

Did you pull the axle out? It makes it easier.

I have tried to, but the bearing behind the wheel bearing is keeping it in. That bearing is the cause of all this trouble. Do i just need to pull harder or what?

On a '99, you have the bub assembly. Behind that is a knuckle seal, used to keep the vacuum seal for your hubs and keep stuff out of your bearings. In order to get that out, you need to pry the axle out with a pry bar between the u-joint and the knuckle. If the seal still won't come out, you may need to beat the seal out from behind with a screwdriver or something. This site goes over the procedure with pictures, Ford Super Duty Ball Joint Replacement Procedure | Superdutypsd.com. Good luck.

Thank you! That just made that project ten times easier

Not a problem, make sure you seat the seal right the first time, once it is in the only way to get it out is to destroy it.

Ok. I'll make sure to do that. Thank you again tho. I thought i was gonna have to spend several days on this project
