How do you replace rear shocks on a 1992 Buick roadmaster wagon?

To replace the rear shocks on a 1992 Buick Roadmaster wagon, start by safely lifting the rear of the vehicle and securing it on jack stands. Remove the lower shock mount nut using a wrench, then pull the shock out from the bottom and detach it from the upper mount. Install the new shock by positioning it in the upper mount first, then securing the lower mount with the nut. Finally, lower the vehicle and repeat the process on the other side if necessary.
