Upper Ball Joint, Front

The first step is to remove the steering knuckle with its axle hub followed by upper ball joint disassembly through wire and boot removal and snap ring extraction using an expander tool. Finish the operation with Special Service Tool: 09950-40011 (several tool options included) and deep socket wrench to separate the ball joint and inspect its rotator condition before securing the ball joint stud with a torque wrench to the suggested specifications. The ball joint inspection requires flipping the ball joint stud five times in alternating directions before nut application through the use of a torque wrench to accomplish steady nut rotation at 2-4 second intervals during which the fifth reading should fall within 0.7 - 4.4 Nm (7 - 45 kgf-cm, 6 - 39 inch lbs.). The installation of a new ball joint requires Special Service Tool: 09309-37010 with a socket wrench and press to install the joint followed by using a snap ring expander with new snap ring insertion before boot installation that uses new wire secured with provided grease before reinstallation of steering knuckle with axle hub.

Service and repair the front upper ball joint requires a complete removal of the steering knuckle with axle hub followed by front upper ball joint removal. Start the procedure by taking off both wire and boot before applying the snap ring expander tool to remove the snap ring. The process requires Special Service Tool: 09950-40011 (09951-04010, 09952-04010, 09953-04020, 09954-04010, 09955-04031, 09957-04010, 09958-04011) and a deep socket wrench for removing the upper ball joint. During inspection of the ball joint boot for the front upper assembly you must examine for damage while testing rotation by performing five cycles of motion on the ball joint stud before applying the nut. Turn the nut with a torque wrench at a constant rate of one full turn throughout 2 to 4 seconds during which time you should note the torque reading on the fifth turn at a range of 0.7 - 4.4 Nm (7 - 45 kgf-cm, 6 - 39 inch lbs.). Special Service Tool: 09309-37010 and a socket wrench should be used to press in a new ball joint followed by the installation of a new snap ring through snap ring expander application. The replacement process ends by installing the boot and wire with new material while using kit-supplied grease. Afterward, rebuild the steering knuckle and axle hub assembly.

A mechanic should start the upper ball joint servicing by taking off both the steering knuckle with axle hub and the upper ball joint. Initiate service by first stripping off the wire along with boot followed by installation of a snap ring expander to extract the snap ring. The upper ball joint can be detached with the help of Special Service Tool: 09950-40011 (series of tools included: 09951-04010, 09952-04010, 09953-04020, 09954-04010, 09955-04031, 09957-04010, 09958-04011) and a deep socket wrench. Test the ball joint boot for damages and perform a ball joint stud rotation check through five movements before tightening the nut. A torque wrench needs continuous use for 2 to 4 seconds to reach one full turn every 5th time while recording torque measurements at 0.7 - 4.4 Nm (7 - 45 kgf-cm, 6 - 39 inch lbs.). The proper installation requires using Special Service Tool: 09309-37010 along with a socket wrench to install a new ball joint then completing installation with a new snap ring with the aid of a snap ring expander. The last step requires users to place a new boot and wire after applying the provided grease to the boot. Then users can reinstall the steering knuckle and axle hub.

The service and repair of upper ball joints requires removal of the steering knuckle with axle hub from models RZN191L-TRPDKAB, RZN196L-CRPDKAB, PZN196L-PRPDKAB, VZN195L-CRPDKAB, and VZN195L-PRPDKAB. The ball joint upper nut installation requires flipping the ball joint stud for five rotations followed by a torque wrench operation at 2 to 4 second intervals until the fifth turn to measure the torque value which should fall within the range of 0.7-4.4 Nm (7 - 45 kgf-cm, 6 - 39 inch lbs.). Placement of the upper ball joint requires wireless boot removal followed by snap ring expulsion with a ring expander tool before using Special Service Tool: 09950-40011 in conjunction with supporting tools starting from deep socket wrench to finish the operation. The installation process of the new upper ball joint requires Special Service Tool: 09309-37010 with a socket wrench followed by snap ring installation using a snap ring expander and lastly securing the new boot with wire using the supplied grease from the kit. Cut off the process with axle hub installation of the steering knuckle.

Begin by removing the front wheel, ensuring a torque of 110 Nm (1,150 kgf.cm, 83 ft. lbs.).

Take off the wire and boot, use a snap ring expander to detach the snap ring, and employ Special Service Tool: 09950-40011 along with a deep socket wrench to extract the upper ball joint.

Remove the cotter pin and nut with a torque of 142 Nm (1,450 kgf-cm, 105 ft. lbs.), then use Special Service Tool: 09628-62011 to disconnect it from the lower suspension arm, ensuring that the cotter pin hole of the lower ball joint faces forward during installation.

Using a torque wrench, turn the nut continuously one turn every 2 - 4 seconds and take the torque reading on the 5th turn, aiming for a turning torque of 0.1 - 2.5 Nm (1 - 25 kgf-cm, 0.8 - 21.7 inch lbs.).

Reinstall the steering knuckle with the axle hub.

Remove the cotter pin and nut with a torque of 72 Nm (730 kgf-cm, 53 ft. lbs.). If the holes for the cotter pin are misaligned during installation, tighten the nut further up to 60°.

Use a torque wrench to turn the nut continuously for one full turn every 2 to 4 seconds, recording the torque reading on the fifth turn, which should be between 0.7 - 4.4 Nm (7 - 45 kgf-cm, 6 - 39 inch lbs.).

Utilize Special Service Tool: 09628-62011.

First, remove the front wheel and loosen the front lower ball joint bolts without removing them. Then, remove the tie rod end sub-assembly by taking out the cotter pin and nut, and use Special Service Tool: 09610-20012 to disconnect the tie rod end from the lower ball joint.

Use Special Service Tool: 09309-37010 and a socket wrench to press in a new ball joint.

Using a torque wrench, turn the nut continuously 1 turn every 2 - 4 seconds and take the torque reading on the 5th turn, aiming for a turning torque of 0.1 - 3.45 Nm (1 - 35 kgf-cm, 0.8 - 30 inch lbs.).

Remove the steering knuckle with the axle hub.

Reinstall the front wheel, torquing to 110 Nm.

Begin by removing the front wheel, ensuring a torque of 110 Nm (1,150 kgf-cm, 83 ft. lbs.).

Disconnect the tie rod end by removing the cotter pin and nut, and use Special Service Tool: 09610-20012 to disconnect it from the lower ball joint.

Install a new boot secured with a new wire, utilizing the grease supplied in the kit.

Tighten the lower ball joint set 4 bolts to 80 Nm (820 kgf-cm, 59 ft. lbs.).

Connect the tie rod end using a nut and a new cotter pin, torquing to 91 Nm (930 kgf-cm, 67 ft. lbs.). If the cotter pin holes are misaligned, tighten the nut an additional 60°.

Begin by removing the front wheel.

Inspect the upper ball joint boot for any damage and check the rotation condition by flipping the ball joint stud back and forth five times.

Secure the lower ball joint with the set nut and a new cotter pin, applying a torque of 140 Nm (1,450 kgf-cm, 103 ft. lbs.). If the cotter pin holes are misaligned, tighten the nut an additional 60°.
