My 94 has 457k on it i am getting an insane amount of what sound like road noise or a cupped tire.I know this has been discussed before but i have it narrowed down to two things that could be causing it wheel bearings or axles it is a speed dependent noise and sounds like a super swamper running down the road im lookin for a second opinion on this so i know if im replacing axles or wheel bearings....hoping for axles
