Coil Spring, Front

The replacement process of a coil spring begins with vehicle lifting and proper suspension methods. Start by taking off tires and wheels before you support the lower Control Arm with the proper jack. The automatic level control air tube needs detachment from the Shock Absorber before removing both the Shock Absorber lower retaining bolt and the adjustment link retaining nut. The universal steering linkage puller (J24319-B) should be used to detach the adjustment link from the lower Control Arm. Lower the Control Arm gradually while letting it settle onto the rear support. Use a pry bar to do the following steps: detach coil spring lower insulator and extract coil spring and insulator before pulling down to remove upper insulator. Start by installing the upper insulator to the body while simultaneously placing the lower insulator onto the lower Control Arm. Set the coil spring correctly in the lower Control Arm while making sure the insulator snaps into position. Put the lower Control Arm in a raised position before installing Shock Absorber retaining bolts at 25 nm torque (18 ft. Lbs.). You should install the adjustment link to the lower Control Arm then lock it in place using a 75 nm (55 ft. Lbs.) torque setting on the adjustment link retaining nut. The alc system requires a 45-second active running control phase to fill shock absorbers with residual pressure before moving forward with wheel placement. Begin this phase by engaging the ignition. Attach the automatic level control air tube to the shock before installing tires and wheels while lowering the vehicle into position.

Use the Strut Rod Nut Socket (J 42991) to remove it.

It is used to guide the strut shaft out of the assembly.

Use a socket to hold the strut shaft from turning and remove the 24 mm strut shaft nut with a 24 mm wrench.

Begin by raising and supporting the vehicle.

Remove the absorber lower retaining bolts and the adjustment link retaining nut.

Place the Damper Rod Clamp (J34013-20) on the strut shaft in the strut compressor.

Use the Alignment Rod (J 34013-38) to guide the strut shaft, then turn the compressor screw clockwise until the strut shaft threads are visible.

Position the spring correctly over the strut and move the assembly upright in the compressor, then install the locking pin.

Install the strut into the Strut Compressor (d 34013-B) and turn the compressor forcing screw until the spring compresses slightly.
