It did shimmy slightly around 60, but this is unrelated to that (flat spotted tires are obvious).
I do admire that he at least did the work, but a visual inspection should make it clear there's a cone on the wheel too... or maybe a quick Googl, or take a look at it before you pull the nuts off. Idk. I'll monkey mechanic a lot of things, but I take wheel/brake/suspension related work VERY seriously and will follow factory torque and procedure religiously, it disappoints me when other people don't do the same because if this were to wear thru and snap a stud or three, it could kill some people.
