Hey guys i have a 2000 grand prix se, 3.1 motor. This car had 15 inch steel wheels. I changed them to 16 inch alloy or mag wheels. they have been fine except twice i sounded like the cv joint was loose but it wasnt. the front rims had the lug nuts(all five on both front rims) so loose the fall off. My question is what if anything could caUSE lug nuts loosin up like that.
