② Boot (LH)(same flow) Replace rack oil seal.
③ Boot (pinion side)(same flow) Replace parts described above.
④ Gear housing tube(same flow) Replace gear housing tube.
Service parts to be prepared
① Rear housing cover and rear housingPinion seal kit

③ Boot (pinion side)Rack oil seal; Pinion seal kit
④ Gear housing tubeGear housing seal kit
All four repair flows share a common bench procedure: (1) Remove gear from vehicle → (2) measure rack starting force and pinion rotating torque → (3) replace the relevant parts → (4) measure pinion rotating torque → (5) adjust adjusting screw → (6) measure rack starting force and pinion rotating torque again.
