Over 30 it would just pop left and right so much it wasn't safe.
Havn't done any testing at all since this just happened this weekend, and I can't work on my car in my apartment complex.
Not sure about the noises, was more concerned with not hitting things.

How can I tell if it's differentiating? More specific, what should happen when jacked up, in 4, locked, in gear/out of gear, etc.?
