I remember a time when alignment service was a stand alone facility. Same thing with auto electrical service that did tune ups using oscilloscopes and dwell meters. I haven't had an alignment problem with a front wheel drive vehicle in almost forty years. Who remembers the shims that were used to align the old rear wheel drive vehicles that used short/long arm suspension arrangements? Seems like the alignment shops could get the proper alignment on the machine, but never with the vehicle going down the road. And how many remember vehicles coming back from being aligned with the steering wheel off-center?
