Not sure that putting a torque wrench on a nut that has been tightened for a while gives an accurate reading. A nut torqued to 100 ft lb may take more than 100 ft lb to break loose after some time. Wheels would have come off for half shaft bolt replacement. As posted recently, it's a good idea to see if the index paint marks on the outer axle nuts are aligned. Those nuts may back themselves off a bit.
Can you tell us how the wheel scuffing was fixed? Buffing? Touch up paint for these wheels does not exist.
