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

Service and repair of the upper control arm starts with turning off electrical power to the air suspension to stop unexpected air spring inflation or deflation before hoisting, jacking or towing processes begin. The air suspension service switch must be turned to an off position. The hand removal sequence begins with the shock absorber and spring assembly followed by the upper arm, nuts, bolts removal where the spent nuts must be discarded. During upper arm installation users should tighten the upper arm-to-crossmember hardware loosely until all operations finish with the vehicle resting on its wheels and tires. Complete the front end check after finishing the process.

The upper control arm service and repair process depends heavily on proper understanding that suspension fasteners represent vital elements that determine system performance and broken fastener failures result in expensive service-related costs. It is essential to use new fasteners that bear the same part number or equal-rated alternative components which should never include inferior replacement designs. The correct torque specifications must guide reinstallations and fasteners in their normal mounting direction on every rear suspension arm. The safe method to prevent accidental air spring changes during hoisting jacking or towing operations requires operators to disable the air suspension service switch. Record the wheel hub center to fender lip distance measurement when the vehicle rests on level ground for future guide in installation. Wheels should be detached first followed by gradual removal of right suspension arm-to-axle bracket bolts to prevent damage to the brake line. Throw away the flag nut before taking out the bolt as well as the upper arm. You can switch the rear suspension upper arms between the left and right positions but their labeling indicates correct front or outboard positioning when you install them. Use a suitable lifting system to elevate the suspension until the wheel hub center stands at the same distance from the fender lip as was recorded during disassembly. Follow the backward process to install the component.

Begin servicing or repairing the upper control arm while the air suspension electrical power is off because unexpected air spring inflation or deflation might shift the vehicle position. The first step requires users to deactivate the air suspension service switch. After the shock absorber and spring assembly detachment start taking away the retainers from the arm. The service sequence requires removal of the nuts along with the bolts and upper arm and proper discarding of the nuts. It is essential to keep upper arm-to-crossmember nuts and bolts in a snug position during the installation process until the weight of the vehicle is resting on the wheel and tire assemblies. Once all processes are complete check and undertake front end alignment if needed.

Do not remove the cam bolt to avoid damaging the steering bellows boot; instead, remove and discard the nut.

Ensure that the electrical power to the air suspension system is turned off to prevent unexpected inflation or deflation of the air springs.

Ensure that specified torque values are adhered to for proper retention.

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

Carefully detach them without using excessive force to avoid damaging the brake line.

Do not fully tighten until the installation is complete and the vehicle's weight is on the wheel and tire assemblies.

With the vehicle in neutral and positioned on a hoist, measure the distance from the lip of the fender to the center of the wheel hub for reference during installation.

Start by removing the wheel and tire assembly.

Tighten the two upper arm nuts to 150 Nm (111 lb-ft).

To prevent the vehicle from shifting during operations due to unexpected inflation or deflation of the air springs.

Remove and discard the bolts and nuts.

Ensure that the electrical power to the air suspension system is turned off to prevent unexpected inflation or deflation of the air springs.

Exercise caution to avoid damaging the brake line.
