Was a cold morning when I started to off I noticed a rotational scraping sound from the front of the truck. The sound started at around 15mph and the frequency of the scraping sound got faster as speed increased. I put the truck in neutral at 30 mph and the sound was still present. It could not have come from the motor or transmission, so I am thinking wheel bearings are shot. I did not drive long after hearing the noise. If it is the bearings, where can I find a good replacement that won't bust my wallet. I priced roller bearings, and the cheapest I found was $98 for the left and right front wheels (inner and outer bearings). Do I really need roller bearings, or can I stick with ball bearings? I appreciate any help y'all can provide. Thanks!
