The rear shocks in your Chevy Lumina absorb imperfections in the road as you drive. This provides the driver and passengers with a smoother ride. Once the gas inside the shocks wears out, the people in the car will feel more bumps due to the shocks inability to rebound. When this happens, you must replace the defective shocks with new ones.
Place a jack under the rear axle, and jack the Lumina off the ground. Place jack stands under the axle, and lower the Lumina onto the jack stands.
Remove the bolt that secures the top of the rear shock to the shock hoop, welded to the underside of the body, using a socket and ratchet.
Remove the lower bolt that holds the bottom of the shock onto the shock hoop welded to the axle housing, using a socket and ratchet.
Pull the shock out of the shock hoops.
Place the top of the new shock into the shock hoop, and secure it, using a socket and ratchet.
Pull down on the shock absorber, until the lower part of the shock rests inside the lower shock hoop. While holding the shock absorber in place, push the bolt through the shock hoop to hold the shock in place.
Secure the lower shock to the shock hoop, using the socket and ratchet.
