might be a dumb question, but how can i tell if mine are loose?

Mine sounded like a clunking noise when going over a slightly bumpy road at about 25 mpth. Usually comes from the right front top nut. If you take the front wheels off you can check them all but it can be a PITA since it has a allen head stud. The bottom nuts were even more difficult to get to, I recommend taking it to the dealer and have them replaced since it's a TSB. Make sure they use the nuts on the TSB and torque to spec.

Use crows foot at 90deg angle. No calculation needed.

Ummm check them with a wrench maybe? If you can turn them then they’re loose. Lol. Just sayin.

You don’t need locktite with selfies locking nuts. These are used on aircraft all the time and they don’t come loose. Just sayin.

Didn't have this problem. Tech did check when alignment done and he said it was fine. Mine was built May ' 17 if that is a factor. I've not noticed issue tied to production dates.
