97 GMC Suburban has loud road noise driving 55-65 mph. It can get so loud you feel that the truck is vibrating but you don't feel any loss of control. CV joints replaced, no change. Tires replaced due to cupping, noise gone/lessened for about 100 miles, now it's back. Any ideas?
If the noise came back after new tires got 100 miles on them, check the tires for cupping. If they are, check your alignment and steering components. If not, i would next check the u-joints.
