Also, take a look at the rack and pinion. I installed a lift kit, changing out the CV axles, struts/shocks, balljoints, etc. Afterwards I would get a slight wobble if something threw it off. I already knew my steering rack was about done, so I'm not sure if it was that and/or a combination of needing to redo the alignment, but after both were done, the wobble went away.
