TLDR: Shop doesn't provide printout of post alignment specs, and I discovered that all four tires have different pressures, highest 54, lowest 38. Am pissed because (a) of massive incompetence (you're a tire shop, you have one job) or (b) I suspect a lazy tech monkeyed with pressures to get to in-spec results. How mad should I be?
Saturday I dropped my SAAB off at Mavis to have new Conti's mounted & balanced, and an alignment done. I previously had this same location install tires on another car,and do two other alignments. After drop off I get a call from the counter guy saying that my oil was due for a change, as was my power steering fluid. I explained that I personally changed both four weeks ago. Usual up-sell attempt, no big deal.
My wife drops me and 4 year old off at the shop. At counter, I ask for the alignment printout. The counter guy says "We never give those out." I said: "Without me even asking, you've given me one both times I had an alignment done here, as has every other shop I've ever had do an alignment." Response is: "You should have asked us for one before hand." I say: "But you just said you never give those out." They say: "Well, today there was no paper in the machine." Ugh, the usual nonsense back and forth. They offer to put the car back on the rack, I say not today, as I have my kid with me, and we are already 3 hours after the promised delivery time, but I will be back Monday or Tuesday.
Anywho, this morning I check tire pressures: All four tires have different pressures, highest 54, lowest 38. (Saab specifies 32psi, I run 35.) If all four tires were off by the same amount, I would say "Ah, their shop gauge deviates from my Longacre by Xpsi." But I'm asking myself: Are they are so bad at their job that they didn't check the pressures when they mounted the tires?
I actually suspect that the tech goosed the pressures to get the alignments to spec. Much easier than futzing with the tie rod ends in front, or picking which of four eccentric bolts to turn in the rear. I question the competence of any alignment "specialist" who doesn't check that tires are at their target hot pressure before the car is put on the rack, so if he missed this basic thing, maybe I'd rather that he didn't wrench on my cars... We spend a lot of time with our spec miata playing with camber and ride height, so I am all too well aware of how much even a few psi can throw things off. And that's on a hoosier slick, with relatively stiff sidewalls. On a four season street tire, even more so.
Anyway, for whatever reason the car's alignment is suspect. I need to take it back. I guess this post is just kind of a rant about being disappointed when people don't do the basic things right. How mad should I be? (And I haven't yet retorqued the lugs from what I guess is the 137ftlbs they jammed them in at with the air wrench...)
