Lincoln XL3Z-3084-AA Front Suspension Arm Assembly

On 2WD models, when the vehicle has air suspension, then turn off the air suspension system by using the switch that is in the position of the right kick panel. Unscrew the lug nuts of the wheels, jack the vehicle up and hold it on jackstands and then take out the wheel. Disassemble the disc brake caliper, brake pads, caliper anchor bracket and the disc then the disc brake splash shield. Take out the shock absorber and separate the brake hose bracket with the lower control arm. Un screw the front stabilizer bar link nut. Install the compressor with the help of the appropriate coil spring compressor and compress the coil spring. Install the balljoint and screw the steering knuckle and ballstud nut. Install the bracket of the 4WABS front brake anti-lock sensor and screw the bolt firmly. Install the lug nuts, wheel and lug nuts, lower the vehicle and tighten the lug nuts. Install tightening of the upper arm pivot bolt nuts, front nut to be installed first, and reconnect the air suspension system where fitted. In 4WD models with air suspension system, shut it off, loosen the wheel lug nuts, lift the vehicle, put on jackstands and then undo the wheel. Removing of skid plate when fitted. When the car is equipped with a 4-wheel antilock brake system (4WABS) detach the bracket of the anti-lock sensor wire of the front brake control arm. Take off the torsion bar, dis-attach the shock absorber with the lower control arm and the stabilizer bar with the lower control arm. Unscrew the lower balljoint of the steering knuckle with an appropriate puller, handle the loosened ballstud nut attached to the ballstud to avoid violent separation. Take out the lower control arm pivot bolts, nuts and washers and then take out the lower control arm. Inspect the bushings in case of damage or wear. Replacement of control arm should be done when it has welded-in bushings that cannot be replaced, replaceable bushings may be used, then press with special adapters or bring control arm to a repair shop. To install, elevate the control arm into place and add the control arm pivot bolts, washers and nuts but do not tighten them fully at this stage, so that the threaded sections are facing forward. Lift the lower control arm using a floor jack until the balljoint stud is able to fit into the steering knuckle hole, add the balljoint stud nut, loosen it slightly and replace a cotter pin. Install the stabilizer bar to the lower control arm, installment to shock absorber, reinstall torsion bar, and reinstall 4WABS front brake anti-lock sensor wire bracket where necessary. Simulate normal ride height by lifting the lower control arm using a floor jack and loosely tightening the lower control arm pivot bolts. Install the lug nuts, wheel and lug nuts, lower the vehicle and tighten the lug nuts. Fit the skid plate where fitted. Test the ride height of both sides of the vehicle on the same side of both sides of the frame to the ground and when one side is at a higher or lower point than the other, use the torsion bar adjustment screw to adjust the vehicle, rolling up and down with each adjustment to align the suspension and provide an accurate reading.

This procedure applies to both 2WD and 4WD models. If the vehicle is equipped with air suspension, turn off the air suspension system. The switch is located in the area of the right kick panel. Measure the height of the center of the hub to the ground before proceeding. Loosen the wheel lug nuts, raise the front of the vehicle and support it securely on jackstands. Remove the wheel. Position a floor jack, with a wood block on the jack head (to act as a cushion), under the lower control arm in the area between the spring seat and the balljoint. Raise the jack slightly to take the spring pressure off the upper control arm. Mark the position of the upper control arm camber adjustment cam. If the vehicle is equipped with a 4-wheel anti-lock brake system (4WABS), remove the bracket bolt for the wheel speed sensor wire and place the sensor wire out of harm's way. To disconnect the upper control arm from the steering knuckle, remove the cotter pin from the balljoint castle nut, loosen the nut a few turns (don't remove it), install a small puller and break the balljoint loose from the knuckle. Now remove the nut. Remove the upper control arm pivot bolts and nuts. Remove the control arm. Inspect the pivot bolt bushings for wear. If the bushings are worn, you'll have to replace the control arm. Inspect the upper balljoint seal. If it's leaking, replace the control arm. The balljoint is not serviceable. Position the arm in the frame brackets and install new bolts and nuts. They must be installed with their heads facing toward each other. Make sure the marks you made prior to disassembly are aligned, then tighten, but don't torque, the pivot bolt nuts. Attach the balljoint to the steering knuckle and tighten the ballstud nut. Reattach the 4WABS front brake anti-lock sensor wire bracket and tighten the bolt securely. Install the wheel and lug nuts, then lower the vehicle. Tighten the lug nuts. Tighten the upper arm pivot bolt nuts, front nut first. Reactivate the air suspension system, if equipped.
