Dry grinding and/or knocking noise only when backing up

[jontheacrobat]

I have 2010 1500 5.7l V-8 I that has a dry grinding and/or knocking noise coming from the front passenger wheel area. It is only there when backing up. I also noticed what looks like an oil leak (in pic, not to mention it’s on there with a zip tie!!). Brakes seem to be fine. Any ideas?

Check the caliper bolt on the front/top of the caliper. If it's missing (there should be two) your caliper is lifting off the rotor and knocking into the wheel. Otherwise, it could be the CV Shaft, tire rub, or perhaps your wheel well liner is loose and getting caught on the edge of the wheel.
