I have a 2000 F150 and everything is factory still. Can the ball joint on the lower control arm be replaced?

 

Yes. Moog makes a straight replacement and an oversized version, in case the socket is worn.

 

Yes.
But you probably need to replace both lower ball joints, both upper control arms, idler arm, anti-sway bar links, and possibly even tie rod ends. Just rebuild the whole front end and don't mess with it again for several years.

If you're doing it yourself it's not that much more trouble. Of course if you're paying somebody it's a small fortune

 

Thx. Is there a spec on the size of the socket to determine if it is worn enough for the oversized one?

 

Yeah. Have to agree with that. I replaced the passenger side upper last time I worked on (noticed wobble and uneven tire wear). Planning on replacing everything this next time and will do myself. Older and slower but I still like working on it myself. Thx you for the quick response.
