I have been helping a young man, who just moved in across the street, replace the f&r brakes on his Chrysler 200.
I offered him my impact, sockets, torque wrench, etc ... I also offered my guidance/advise/help on a few related tasks.
Turns out he's a recent grad school graduate hired to do software for Chrysler's engine controls/propulsion division.
He wants to learn more about auto mechanical repairs and has taken some of their technical courses for their repair technicians. He's following YouTube videos for the brake How-To's, and is generally doing fine.
He did need help removing a stuck lug nut that was way over torqued (not by him) and became stuck in an extractor when a 3/8"x1/2" adapter also broke off in the extractor. Luckily, I was able to remove the lug nut/extractor/adapter with a 18mm impact socket on a Milwaukee 1/2" M18 impact. It's a monster, and was the cause of the broken adapter. -- I did warned him it could break off a stud if he wasn't careful with it.
He was a bit discouraged, but I think he felt somewhat better when I explained a lot of repairs have some 'gotcha'.
I'm glad to help him out. My son is a brilliant research scientist and my son-in-law a special ed/foot ball coach, but they are not interested in fixing their own cars. When they have to, they can and do fix their cars, but would rather have me do it.
It's funny, 20 years ago I was helping my neighbor's son that lived in the very same house fix his cars.
