Knuckle, Front Driver Side

First service the steering knuckle by unstopping the wheel hub nut and tearing off the brake disc while keeping the wheel speed sensor. After taking out the brake disc you should maintain the tie-rod end nut for discard before separating the tie rod from the wheel knuckle. The wheel speed sensor along with its bolt needs to be extracted from the wheel knuckle where you should place the sensor aside for later use. You should utilize the crowfoot wrench to remove the lower ball joint nut while simultaneously discarding the nut and avoiding stud rotation. The downward movement of the lower arm section enables the ball joint to move away from the wheel knuckle. Steer clear from allowing the halfshaft to extend outward since this will damage the tripod Constant Velocity (CV) joint by separating its internal parts and causing halfshaft failure. Put the Front Wheel Hub Remover between the wheel bearing and hub to push the halfshaft after the wheel bearing and hub support in a stable level position. When working on this task you must first remove both the strut-to-wheel knuckle nut and flagbolt before you take out the wheel knuckle. When necessary you must take out the wheel hub together with the bearing. Installation requires the new wheel knuckle to be positioned first before installing a new strut-to-wheel knuckle nut and flagbolt and tightening them to 175 Nm (129 lb-ft). The installer should support the halfshaft before installing it into the wheel bearing and hub. Lower the arm carefully and position the ball joint stud to enter the wheel knuckle. Tighten the new lower ball joint nut to 150 Nm (111 lb-ft) by using a crowfoot wrench. Fasten the wheel speed sensor with an 8 Nm (71 lb-in) torque. Impose the tie-rod end stud into the wheel knuckle position followed by new tie-rod end nut installation and proper tightness setting to 115 Nm (85 lb-ft). Reinstall the brake disc. Prior to letting the vehicle rest on its wheels the technician should torque the extracted hub nut to 350 Nm (258 lb-ft) while applying brake pressure to stop halfshaft movement before discarding the nut. Apply a new wheel hub nut onto the threads and start tightening it to 350 Nm (258 lb-ft) in less than 5 minutes to trigger the one-time locking chemical mechanism. Place the wheel followed by the tire as the final step.
