How to Replace the Springs in a Chevy Avalanche

The Chevy Avalanche is a sports utility truck with the 1500 and 2500 series. Replacing the springs in the Chevy Avalanche is complicated. Depending on the series, you may have to remove the engine protection shield, frame cross bar, tire and wheel assembly, shock absorber and front stabilizer shaft link. Only an experienced home mechanic should replace the springs in a Chevy Avalanche.
