I have an 07 ST 4.6 4x4 with 160,000 miles on her. I'm replacing the front struts with Monroe quick struts. Anyway, noticed my upper control arm bushings are cracked. These are stock so no surprise. It seems that it would be cheaper to replace the UCA's with the Moog problem solvers. The LCA's is a different story price wise. So I'm wondering if I should or can replace the bushings and ball joint on the stock LCA? I'm on a tight budget so any advice would be awesome!
