Coil Spring, Front

Initialization of coil spring replacement in front suspension strut and spring assembly requires the steering wheel to be first unlocked. Take off the upper strut mount nuts before removing the wheel-tire assembly without removing the wheel hub nut. Start by taking away the brake disc and discarding the tie-rod end nut before you manage to separate the tie rod from the wheel knuckle. Start by discarding the stabilizer bar link upper nut then remove the wheel speed sensor harness from the strut and detach the wheel speed sensor from the wheel knuckle before placing it aside. A crowfoot wrench should be used to remove the lower ball joint nut while also discarding it until the stud stops rotating. Lower the arm arm down with caution while clearing the ball joint from the wheel knuckle yet maintaining restraint to stop the halfshaft from moving outboard to prevent damage. To perform the removal use the Front Wheel Hub Remover to push the halfshaft from the wheel bearing and hub when the unit rests in level position. The four bolt upper strut mount nuts need replacement so technicians must remove the wheel knuckle combined with the strut as well as spring assembly. You should discard the strut-to-wheel knuckle nut and flagbolt while requiring separate parts between the strut and spring assembly from the wheel knuckle. Install the wheel knuckle onto the strut and spring by using a new strut-to-wheel knuckle nut and flagbolt which needs tightening to 175 Nm (129 lb-ft). Position the wheel knuckle and strut along with spring assembly then loosely place four new upper strut mount nuts. After halfshaft support, install it into wheel bearing and hub. The ball joint stud should be installed into the wheel knuckle while lowering the lower arm using a crowfoot wrench to install and tighten the new lower ball joint nut to 150 Nm (111 lb-ft). The wheel speed sensor requires its bolt to be tightened to 8 Nm (71 lb-in) and after this step the sensor harness must be attached to the strut. Begin by installing the new stabilizer bar link upper nut before torquing it to 55 Nm (41 lb-ft), proceed to insert the tie-rod end stud into the wheel knuckle then fasten a new tie-rod end nut using 115 Nm (85 lb-ft) torque. Install the brake disc then avoid tightening the front wheel hub nut while the vehicle remains grounded. Follow this step by providing a torque of 350 Nm (258 lb-ft) after engaging the brakes to stop halfshaft rotation. The first step is to install fresh wheel hub nut then apply torque to 350 Nm (258 lb-ft) before starting the wheel hub up to speed. Next, mount the tire and wheel followed by the tight torque of the four upper strut mount nuts to 35 Nm (26 lb-ft).
