How do you replace a rear suspension of a Jeep Commander?

To replace the rear suspension of a Jeep Commander, first ensure the vehicle is safely lifted and secured on jack stands. Remove the rear wheels, then disconnect the shock absorbers and sway bar links, followed by unbolting the lower and upper control arms and the axle. Replace the old components with new ones, reassembling in the reverse order, and ensure all bolts are torqued to the manufacturer specifications before reinstalling the wheels and lowering the vehicle. Finally, perform a wheel alignment to ensure proper handling and tire wear.
