2004 wj, 4.0. Decided to check all the suspension out before installing the 2.5" coil spring lift. All the bushings on the control arms are toast, as well as the tie rod ends, and drag link. Thinking I'm going to replace all of the control arms with Iron Rock control arms at the same time I install the coil springs, shocks, sway bar links. Is anyone aware of any issues I may have with this set up or installation. thanks in advance.
