Before working on the steering knuckle, lift the vehicle up on jackstands or a frame contact hoist and take off the front wheel and tire assembly. Remove the front caliper from the steering knuckle and free the front rotor from the hub. Remove the wheel speed sensor to protect the outer C/V joint when you remove the hub and if the sensor can't move, use a hammer and punch to unseize it, not pliers. After that, take off the hub and bearing retaining nut, along with the three bolts connecting the steering knuckle to the hub and bearing assembly. Should the seal between the hub and bearing assembly jam and it is dislodged while removing it, then it has to be changed, as must any damaged flinger disc. Remove the hub and bearing from their place inside the steering knuckle by gently sliding them out. If it is stuck, carefully pry it out and gently knock the stub shaft with a soft face hammer. Carefully remove both stud nut and bolt so the ball joint seal remains clear of the steering knuckle. With a pry bar, split the ball joint from the steering knuckle and ensure you do not turn the bolts in the steering knuckle as you remove them. Lastly, take out the steering knuckle from the vehicle. Installation should start by connecting the steering knuckle to the ball joint stud and attaching it with the bolt, tightened to a torque of 55 Nm (40 ft. lbs.). Line up the steering knuckle with the strut assembly, avoiding twisting the bolts as you put them in, then tighten the strut clevis to steering knuckle attaching bolt nuts up to 203 Nm (150 ft. lbs.). See that the mounting surfaces are clean and not damaged, then set the hub and bearing assembly onto the stub shaft until it stays in position. Secure the hub and the bearing assembly to the three bolts and use a new retaining nut to fasten them all to 110 Nm (80 ft. lbs.). Cover the speed sensor head with High Temperature Multipurpose E.P. Grease before fitting, install it by hand with a seven Newtons millimetre (six inch pound) torque, replace the front brake rotor and caliper and tighten the caliper bolts to twenty Newtons millimetre (one hundred ninety inch pounds) torque. Following the application of the brakes, tighten the axle retaining nut to 142 Nm (105 ft. lbs.), put the wheel and tire assembly back on and tighten the wheel mounting stud nuts to 135 Nm (100 ft. lbs.) in the correct sequence. When lifted, remove the lift from the vehicle.
