Camber Wear – If the axle has excessive camber, partial or total wear of the shoulder will occur. For static unloaded vehicles, camber readings for steer positions should fall within the range of 0 to 1⁄4 degree positive (0.0 to 2.5 mm), and trailer positions should fall within the range of ± 1⁄4 from 0 degree (± 2.5 mm from 0). Cupping Wear – Any loose or worn component in truck steering or suspension systems can cause odd wear, cupping, and flat spots. Check for loose wheel bearings, worn shock absorbers, steering gear lash, worn tie rod ends, and kingpins. Check for possible mis-mount conditions.
