Ford 6W1Z-3084-B
Upper Control Arm, Front Passenger Side

The replacement of upper control arm suspension fasteners must incorporate new parts that match the original numbers or equivalent standard since poor substitute parts will produce major system breakdowns. The correct reassembly occurs when you follow given torque values to achieve proper retention. Maintenance should begin with turning off the air suspension system electrical power because air spring inflation or deflation could result in unexpected vehicle shift. All vehicles with fire suppression systems require the system to be placed in a depowered status. The technician should position the vehicle into NEUTRAL on a hoist before removing the shock absorber and spring assembly. First detach the wheel speed sensor retainers from the upper arm then remove its two nuts and two bolts while disposing of the old parts. The fasteners on the new upper arm must be tightened to 150 Nm (111 ft. lbs.). The initial step involves tightening fasteners on both upper arm-to-crossmember attachments along with shock absorber components only until the entire installation process concludes and wheel assembly weight activates. The front end alignment requires checking after final installation completion. The driver needs to activate the fire suppression system power after the service work ends.

To prevent vehicle shifting during operations, which could lead to personal injury.

Check and align the front end as necessary, and if equipped with a fire suppression system, repower it.

Loosely install them with the flagnut.

It could cause the vehicle to shift during hoisting, jacking, or towing, potentially resulting in personal injury.

The rear suspension upper arms are interchangeable, with FRONT and OUTBOARD markings for correct positioning.

Reattach the wheel speed sensor retainers to the upper arm, followed by the shock absorber and spring assembly.

Use a suitable jack to raise the suspension until the previously measured distance is achieved.

Always install new fasteners with the same part number or an equivalent part, avoiding any lesser quality or substitute designs.

Use the holding feature to prevent the stud from turning, then remove and discard the lower ball joint nut.

Measure the distance from the lip of the fender to the center of the wheel hub while the vehicle is on level ground.

Discard the nut and bolt, and tighten the new fasteners to 150 Nm (111 lb-ft) during installation.
