How do you replace rear shocks on a Chevy Express?

To replace the rear shocks on a Chevy Express, start by safely lifting the rear of the vehicle and securing it on jack stands. Remove the lower mounting bolt of the shock using a socket wrench, then detach the upper mounting bolt, which may require accessing the upper shock mount from inside the vehicle or under the rear. Install the new shock by reversing the removal process, ensuring bolts are torqued to the manufacturer's specifications. Finally, lower the vehicle and check for proper operation.
