Squeeling poverty hub caps??

Yeah, strange, I thought the lug nuts were not tight. Popped the caps, re-torqued and went for a ride.
No noise. Put the caps back on and the noise was back.
Just a thought,what disc brakes you using? the 73 up Mopar sliding caliper,if the pads are not tight will squeek.
You can bend the ears on the outer pad or use brake pad glue. Had a Charger that did that.
