Need to replace my drive side lower ball joint, looking for it cheap cuz im tight on cash. fleabay has these http://cgi.ebay.com/ebaymotors/2-Low...spagenameZWD1V for a price. Wonder if there worth it or maybe just get from advanced auto parts.

 

The ball joint isn't a serviceable item, you need to replace the control arm.
Check Ebay for the control arm, there cheap.

 

No, suspension restoration parts sells lower ball joint replacements which you need a ball joint press to get in. It will be much easier to replace the whole arm though, because then you get new LCA bushings as well.
