There are aftermarket bushings available for all the control arms; front/rear, upper/lower, and ball joints for the LCA. Replacing them can be a PITA! I've rebushed LCA, bought a used SPC UCA with new bushings, rebushed rear control arms upper, lower and Panhard. The bushing aren't cheap, but less than replacement arms and you live in Arizona so rust shouldn't be a problem.
The LBJ on LCA were beyond me and the bushings would not come out, so I bought new 1Aauto LCA and rebushed them, those bushings came out pretty easy and the LCA came with new LBJ.
Close to $500+ in new Super Pro bushings for all, $400 for the LCA's, $300 for the used UCA and another $250 for new rear arms that I rebushed. So, however you decide to go it isn't cheap!
