My little '86 Mazda is a good example of rotton work. I took it in to have the carb adjusted once (ran poorly in the winter) and when I got it back, the mechanic said "We put the harmonic balancer on crook so it might idle a little rough." For some reason this didn't click in my head- it ran a little better, and I didn't really notice a vibration. One night while driving to Denver the harmoic balancer FELL OFF! A Denver shop fixed it (had to JB weld the crank where it was wallowed out) and I haven't had any problems since. Don't go to that shop any more.
I usually go to walmart to replace my tires, and have had huge problems with the tire monkeys swapping different lugs onto my truck- I've probably replaced six lugs because those stupid assholes couldn't figure out what nuts go on which vehicle. They always cross thread them, tighten the s*** out of them, and then tell me I put the wrong lug nuts on my truck.
