How do you replace rear strut on a 2013 Impala?

To replace the rear strut on a 2013 Chevy Impala, first, safely lift the rear of the vehicle and support it with jack stands. Remove the rear wheels, then unbolt the strut from the lower control arm and the upper mount inside the trunk. Replace the old strut with the new one, ensuring all bolts are torqued to specifications, and then reassemble by putting the wheels back on and lowering the vehicle. Always check for proper alignment and test drive to ensure everything is functioning correctly.
