How do you change lower control arm bushings on a 2005 Pontiac Montana?

To change the lower control arm bushings on a 2005 Pontiac Montana, first lift the vehicle and secure it on jack stands. Remove the wheel and brake components to access the control arm. Use a socket set to detach the control arm from the chassis and the steering knuckle, then press out the old bushings using a bushing removal tool. Install the new bushings, reattach the control arm, and ensure everything is properly torqued before reinstalling the wheel.
