Chevrolet Express 2500 rear axle clunking and grabbing when turning slowly on Chevrolet Express 2500

Some Chevrolet Express 2500 owners report experiencing rear axle clunking and grabbing issues when turning slowly, particularly at low speeds during initial acceleration or deceleration. These owners note that the clunking sound can occur randomly, especially when letting off the throttle and then accelerating again, which may suggest problems with engine/trans alignment or rear axle u-bolts. Additionally, some have found that shaking the truck side to side while parked can recreate the loud clunking noise, indicating potential issues with the rear axle or suspension components. Others have reported knocking or clunking noises during acceleration or deceleration, pointing to possible drivetrain or rear axle component problems. Furthermore, grabbing sensations when shaking the rear tires may indicate movement in the axleshaft within the housing, suggesting an axle-related issue. To mitigate these concerns, it is advisable for owners to check and adjust the rear axle u-bolts, inspect leaf springs for alignment, and ensure the axle lubricant is free from contamination to avoid further complications.
