1. Disconnect the ground wire from the battery.
2. Remove the engine cover. Engine cover - 4.0L (12.30.50)
3. Drain the fluid from the power steering reservoir.
- Remove the filler cap.
- Install the filler cap.
4. Lay down an absorbent cloth to soak up spilled liquid.
5.
WARNING: Make sure the area around the contact surfaces and connections is clean before you start disconnecting or dismantling parts. Plug all open connections to avoid contamination of the system.
NOTE: Some fluid will inevitably spill during this operation.
NOTE: Drive belt contamination should be avoided.
Disconnect the union of the pipeline of a high pressure of the amplifier of a steering.
- Turn out a bolt.
- Remove and discard 2 sealing washers.
- Place a container to collect liquid.
6. Install the special tools on the high pressure port of the power steering booster.
- Install the sealing ring.
- Tie a pressure gauge to the side under the hood.
7. Install the special tool on the high pressure connection.
- Install o-rings.
- Connect the special tool line to the special tool valve block.
8. Fill the power steering reservoir. Remove the filler cap.
9. Connect the ground wire to the battery.
10.
NOTE: Check for leaks from steering system components and test equipment.
NOTE: Maintain the maximum fluid level while performing the check.
NOTE: Make sure the steering system is installed straight ahead.
NOTE: Under no circumstances remove the low pressure bushing from the power steering pump.
Start the engine with the check valve open.
- Start the engine, turn the steering wheel between the extreme positions, and then stop the engine.
- Add fluid to the power steering reservoir.
- Install the reservoir filler cap.
11. For correct power steering pressures, see the steering system specifications section.
12. With the engine running at idle, turn the steering wheel and hold it fully. Record the pressure reading.
13. Repeat the above procedure on the other side. Record the pressure reading.
14. With the engine running at idle, release the steering wheel. The pressure must not exceed the set value. If the pressure is outside the specified range, this indicates a malfunction.
15. To determine which component is faulty, the steering pump or steering rack, close the test valve for no more than 5 seconds.
16. If the pressure readings are outside the specified range, replace the power steering pump.
17. If the maximum pressure of the pump meets the requirements, the steering rack may be faulty.
18. Upon completion of the check, turn off the engine, disconnect the ground wire from the battery and pump out the power steering fluid from the reservoir.
- Remove the filler cap.
- Install the filler cap.
19. Disassemble the equipment for testing.
20. Connect the high pressure line to the power steering pump.
- Clean the contact surfaces of the parts.
- Install new o-rings.
- Tighten the bolt with a torque of 25 Nm.
21. Install the engine cover. Engine cover - 4.0L (12.30.50)
22. Connect the ground wire to the battery.
23. Fill fluid into the power steering system and bleed air from the system. Filling and bleeding the power steering system.
