I hope they checked mine right. I know I've read sometimes you have to check the ball joints a certain way. Like with and without load, etc. or you could get a wrong reading.
I need to get a new tire put on and a rotation. When I do that, I may take it to another shop to get the tire put on and have them check the front steering out while they do that just to make sure there isn't anything wrong. As I wonder how good of a job they did checking the front steering, plus all the other things they say they check all for a $20 oil change.
I know on the coupon thing I got in the mail for the $20 oil change. It had a list of things they check. And one was "Thermostat Operation". I asked the guy how they check that. And he said they have a tool that tells them when the thermostat opens. But when the guy started it up after they did the oil change. They didn't run it long enough to get the thermostat open before they drove it out of the shop. So, I really doubt they did that thermostat check and probably didn't do all the other checks they have listed.
A few months ago, I found the 2 lower bolts on the driver front shock were barely on there. As one day I had noticed one of the bolts were sticking up a half an inch. Then found they were barely on. So, there had been 3-4 different shops miss that.
