Next, remove the three bolts that secure the upper strut mount to the vehicle. To remove the strut, pull down on a lower control arm to pull the stud of the ball joint from the bore. On some Altimas, you might have to remove the front bolt of the lower control arm and slide it out of the pocket in the subframe to create enough clearance to remove the strut and knuckle together. Insert a flat chisel in the groove and remove the knuckle from the old strut. The PRT replacement strut matches the original unit for fit, form, and function. The unit use a spring that matches the application and trim level, so the right height is not altered. This is critical for the lane departure camera and forward sensing radar systems. Attach the knuckle to the new strut. Maneuver the strut and knuckle into the wheel well. Attach the upper strut mount bolts.

Insert the axle shaft into the knuckle and slide the ball joint into the bore at the bottom of the knuckle. You can now push the control arm back into place and install the bolt. Install the pinch bolts for the strut and ball joint. Next, install the tie rod end and the sway bar link. Install the wheel speed sensor into the knuckle and attach the harness into the bracket on the strut. Install the brake rotor and caliper. Attach the brake hose bracket. Tighten the axle nut to 135 foot pounds. Tighten the tie rod end to 25 foot pounds. Tighten the strut pinch bolt to 66 foot pounds. The caliper bracket has a torque specification of 107 foot pounds.
