The service and repair process for lower control arms requires disabling the
Air Suspension electrical power through the RH kick panel switch to stop unpredictable air spring inflation or deflation. Rise and stabilize the vehicle before you take away the tire and wheel assembly even though you must not employ heat to break free stuck wheel nuts because this method may damage both the wheel and bearings. To begin repairs start by taking off the brake disc shield followed by removing the upper
Shock Absorber nut and washer and front shock absorber by untightening its two nuts. First detach the brake hose bracket screw together with its bracket at the front suspension lower arm. Next remove the front stabilizer bar link nut. Deploy the Coil Spring Compressor to compress the front coil spring until you can get rid of the lower
Ball Joint castle nut after removing the attached cotter pin. The Pitman Arm Puller helps eliminate the lower ball joint from its connection to the front wheel
Spindle after repositioning the front suspension lower arm nut for future installation. To remove the front suspension lower arm together with the front coil spring start by removing the two lower arm nuts and bolts. When placing the front coil spring on the front suspension lower arm it should be positioned to show the first hole while revealing the second hole. Nut installation of the front suspension lower arm should be done to original specifications while keeping in mind that production adjustment of the caster split adjuster remains forbidden. Install the castle nut onto the lower ball joint first and add the new cotter pin while maintaining curb position ride height on the control arms. Then tighten the forward front suspension lower arm nut before putting the front stabilizer bar link nut onto its place. Begin by taking out the Coil Spring Compressor as you implement the front shock absorber with its respective lower nuts. The installation process requires attachment of the upper shock absorber nut and washer preceding the installation of the brake hose bracket screw and brake disc shield. Wheel hub assembly recipients require cleaning for achieving appropriate metal-lock contact because foreign debris and corrosion spaced between the hub and wheel can loosen nuts in ways that risk control instability. Before putting on the tire and wheel assembly the air suspension should be turned on if it exists in the vehicle. The last step entails both inspection and adjustment of the front end alignment.
