Coil Spring, Front

Start by elevating the vehicle and supporting it before you take off the wheel and tire for coil spring removal. Set up a suitable jack to support the outboard end of the lower Control Arm before working on it. Before beginning the process start by taking out the stabilizer shaft link lower mounting bolt along with the Shock Absorber lower mounting bolt and automatic level control sensor link from the lower Control Arm. Lower the Control Arm with the jack at a slow pace until spring pressure escapes before using a downward force to take out the spring. Install the spring (without insulators) by placing it on a flat surface to achieve proper orientation before it stands straight on its lower end. After installing the coil spring position an under-jack torque device near the lower Control Arm's outboard end. Position the knuckle onto the Control Arm and fasten the nut by tightening it to 102 nm (75 ft. Lbs.). Install the lower Shock Absorber damping bolt followed by tightening the nut to 102 nm (75 ft. Lbs.). Finally, install the stabilizer shaft link lower damping bolt. Switch on the ignition before wheel drop then wait 45 seconds to let the alc system run its arc while the shock absorbers fill with residual pressure. Lower the vehicle while the suspension reaches its designed trim height and tighten the lower Control Arm inner nuts to 108 nm (80 ft. Lbs.) and the stabilizer link lower attachment to 52 nm (38 ft. Lbs.). Install the wheel and tire before torquing the wheel nuts to reach 190 nm (140 ft. Lbs.).

Carefully handle it to avoid chipping or cracking the coating, as this may lead to spring breakage.

Insert the Strut Alignment Rod (J34013-38) to guide the strut shaft, then turn the compressor screw clockwise to center the strut shaft in the assembly until the threads are visible.

A socket is used to hold the strut shaft while removing the 24 mm strut shaft nut with a 24 mm wrench.

Slowly lower the control arm with the jack until the spring pressure is released, then pull the lower control arm downward to remove the spring.
