Rear Shocks Installation

To replace the rear shocks on a MKZ you will need to remove the upper shock bracket and the lower shock bolt. The bracket is tightened down underneath the cars body and is held up using 2 bolts. The lower bolt goes through the frame and the shock on the bottom of the rear suspension. Once the shock and bracket is off you will need to remove the upper shock bolt which goes through the upper bracket you already removed.

With it installed you can now reverse the procedure and install the shock and bracket into the car and tighten the upper bolts to 38 ft-lbs.
