So I'm getting ready to tear down the front suspension on my Blazer to replace the control arms and bushings. Afterwards it needs a complete re-alignment. Have been reading about the equipment needed to do this myself, including a caster/camber gauge and parallel lines to set toe. According to some sources, with this equipment and careful work, a vehicle can be aligned this way much better than the shop will do it. Has anyone here ever tried this? I'd like to hear how it went. Thanks.
