Metco Motorsports PN MCA00016
1998+ Ford Crown Victoria / Mercury Grand Marquis / Lincoln Town Car and Mercury Marauder
Note to Installer: All work should be performed on a suitable, level surface with the vehicle properly supported.
- It is necessary to raise the rear portion of the vehicle to replace the upper and lower control arms. Securely support the vehicle on each side approximately 7 inches forward of each lower control arm forward attachment point. The rear axle should be supported by a hydraulic jack at about the mid-point of its up/down travel range.
- Both rear wheels should be removed for easier access to the control arm fasteners.
- The Metco Motorsports control arms are designed as direct replacements for the factory arms and the factory fasteners (or suitable equivalents) should be re-used.
- The control arms should be changed one at a time to maintain the general alignment of the rear axle assembly during the replacement process. The fasteners for each control arm should be left loose until all four control arms have been replaced.
- Install the lower control arms with the grease fittings facing down. The upper control arms install with the narrow end at the axle housing and the wider end at the chassis. Position the upper control arms so that the grease fittings at the axle end face upwards.
- Install rear wheels and torque to spec.
- The control arm fasteners should be tightened to the factory specifications to ensure no side-to-side movement of the control arms. (Upper arm-to-frame bolt and flag nut 150 Nm (111 ft. lbs.) Upper arm-to-axle bolt and flag nut 93 Nm (69 ft. lbs.) Lower arm-to-frame bolt and flag nut 150 Nm (111 ft. lbs.) Lower arm-to-axle nut and bolt 150 Nm (111 ft. lbs.)) The control arms should be torqued with the vehicle’s weight on the suspension to avoid creating an unwanted preload condition. Use extreme caution and keep jack stands under the vehicle while performing this step.
- The bushings should be lubricated using a quality chassis lube or polyurethane lubricant, using caution not to add too much lubricant which can cause deformation of the bushings.
- The control arm fasteners should be checked for proper tightness after 50-100 miles of driving.
