Assumption: This guide covers replacing all four shock absorbers on your Sierra.

🔧 Shock Absorbers - Replacement

Your shocks control bounce and keep the tires planted on rough roads. On your Sierra, worn shocks can cause extra body roll, longer stopping distances, and a rough ride. Replacing them in pairs keeps the truck balanced and stable.

Difficulty Level: Intermediate | Estimated Time: 2-4 hours

• If a shock is rusty, use penetrating oil and let it soak before removal.
