8. Remove and discard the nut securing the left ball joint to the steering knuckle.
9. Screw the M14 nut onto the end of the ball joint flush with the end of the threaded part of the joint.
10. Using the LRT-57-036 tool, separate the ball pin from the steering knuckle. Remove the M14 nut and pull the ball pin out of the steering knuckle.
CAUTION: Make sure that the ball joint boot is not damaged. A damaged boot will cause the ball joint to fail.
11. Loosen the nut securing the vertical body position sensor rod to the lower arm and release the rod.
CAUTION: Hold the ball joint from turning using an open-end wrench placed on the flat grooves.
12. Loosen the bolt securing the lower arm to the subframe by a quarter of a turn.
13. Remove the nut securing the lower arm ball joint to the wheel bearing support.
14. Using the LRT-54-027 tool, release the lower arm ball joint and separate the lower arm from the wheel bearing support.
CAUTION: Make sure that the ball joint boot is not damaged. A damaged boot will cause the ball joint to fail.
15. Loosen the tie rod to subframe mounting bolt by a quarter of a turn.
16. Unscrew the nut securing the rod to the ball joint.
17. Using the LRT-54-027 tool, separate the tie rod from the ball joint.
CAUTION: Make sure that the ball joint boot is not damaged. A damaged boot will cause the ball joint to fail.
18. Install the central screw LRT-60-030/3 into the device LRT-60-030/1 and connect it to the hub through the intermediate flange LRT-60-030/2. Secure the connection with the nut LRT-60-030/5.
19. Tighten the center screw to press the drive shaft out of the wheel hub.
20. Remove the devices.
21. Place a container to collect any leaking oil.
22. Install the LRT-54-026 tool onto the drive shaft inner joint.
23. Separate the drive shaft from the differential using levers.
24. Release the drive shaft from the hub.
25. Remove the drive shaft assembly and keep it horizontal to avoid damaging the differential seal.
26. Remove and discard the drive shaft retaining ring.

10. Screw the nut onto the LRT-60-030/4 tool and, while tightening the nut, press the drive shaft into the hub.
11. Remove the devices.
12. Clean the conical surfaces of the ball joints and the sockets for their installation from dirt.
13. Connect the rod to the ball joint, install a new mounting nut and tighten it to a torque of 80 N·m.
14. Attach the lower arm ball joint to the wheel bearing support, screw on the mounting nut and tighten it to a torque of 80 N·m.
15. Connect the vertical body position sensor rod to the lower arm and tighten the mounting nut to a torque of 8 N·m.
CAUTION: Make sure the sensor lever is facing outward.
16. Connect the ball joint pin to the steering knuckle, install a new nut and tighten it to a torque of 80 N·m.
17. Clean the surface of the wheel speed sensor, apply anti-seize lubricant to the sensor, and install it on the wheel bearing support.
