I can see you just love to make friend's don't ya?
I know what the two are, you don't have to be a smart ass about it, but I don't deal with alignments on a consistant basis. I recall my teacher telling me something about alignments causing a wheel shimmy, especially in GM vehicles. That's why i threw out that idea as a possibility. Obviously, when you're lowering a car, you're increasing positive caster, too much positive caster, and you get wheel shimmy. Some people consider wheel shimmy (that rapid side to side movement) vibration, it's really how a person describes a situation. This condition will especially be true at low speeds.
And dude what kinda of an explaintion is camber that you gave? If you look at a wheel and tire set from the front of the vehicle, the tilt of the tire from a 90 deg horizontal line is your camber angle. Caster definition...yah, all accept that although I would have said from top ball joint to lower ball joint.
And my friend, you're obviously in a horrid shop, with horrid pay apparently, because auto industry pays quite well, so as long as you are certified, and you obviously have to put your time in. You do start on crackhead wages, and usually you're put on the lube rack first, joy lots of fun changings oils, but once you have that certification, from what I have seen, people make quite respectable pay. The respect part...ah we could go on for days on this, the problem I find is other techs find incorrect stuff. Best example happened last Thursday, a guy with a 2000 Mustang GT comes in saying he needs new rear pads, based on a recommendation at the Ford Dealer...AT THE FREAKING DEALER. I pull the tire, the rear caliper off, pad is still halfway decent, he tells me the dealer told him the pads where about done. I swear whoever told him that was probably on crack that day, as the pads where just fine, no signs of cracks, plenty of material still left, even the disc is fine, no signs of scoring, quite clean as if it had been resurfaced the day before, no cracks either. I forget what the measurements were, but stories like these are what gives the entire industry a bad rep. This story has happened more often that not, and sometimes I begin to wonder. Guy thanked me and was on his way, and was quite happy with me. The problem I see when working in a big shop is you never get to talk with the customer on what you saw, and actually show the customer what you are describing. The only thing though, is I seem to fix more Fords than any other make...go figure :thinking:
