I have a 99 Express G1500 Conversion and my front driver side inner and outer wheel bearings need to be changed every 4 - 6 weeks. I mean the bearings just literally fall out of the hub. I relaced the rotor NEW with 2 new bearings 6 weeks ago and this morning i heard a noise like usual and when i removed the lug nut cover on the wheel the individual bearings were piled up inside and fell to the floor while the bearing housing was split in 2 peices and just a mess of grease and loose bearings. Can anyone shed some ideas?
