7.2.8.3 Steering hydraulic pressure inspection 

1. 

Disconnect oil outlet tube of power steering pump asembly refer to 7.2.8.6 replacement of power steering oil 
intake and outlet tube. 

2. 

As shown in figure, install hydraulic force testing 
tool. 

Notes: 

The valve of the tool shall be in the open position 
when initial checking. 

3. 

For exhaust of power steering system, refer to 
7.2.8.7 Exhaust procedures of power steering 
system. 

4. 

Preheat power steering oil, start engine to make it 
run at idle speed. 

5. 

Turn steering wheel from left bottom to right 
bottom for several times to make oil temperature 
increase.

6. 

Keep the engine running in idle mode, close the 
tool valve and observe and record the reaadings 
from the pressure gauge. 

Min. oil pressure: 6,400 kPa (928 psi) 

If the power steering pump assembly is damaged due 
to low oil pressure, replace the power steering pump 
assembly damaged. Refer to 7.2.8.10 replacement of 
power steering pump assembly. 

Warning! 

The special tool valve shall not be closed more than 
5s; otherwise, the oil temperature is too high, so that 
the power steering pump assembly will be damaged. 

NL07-0006b

7. 

Keep the engine running in the idle mode and 
open the valve. 

8. 

Have the engine run at a RPM ranging from 
1,000 to 3,000 to measure the oil pressure when 
the engine revolving speed is 1,000 rpm and 
3,000rpm. 

oil pressure differential:490kPa (71 psi) or much less 

Note: Do not turn the steering wheel. 

If the power steering pump assembly flow control 
valve is damaged due to excessive oil pressure 
difference, repair or replace the power steering pump 
assembly. refer to 7.2.8.10 replacement of power 
Steering Pump Assembly. 

If the hydraulic oil path of the power steering system 
blocks or leaks, wash and repair the hydraulic pipeline 
or replace the relevant parts. 

NL07-0007b

9. 

Have the engine run in idle mode, fully open the 
valve and thoroughly turn the steering wheel 
counterclockwise or clockwise to measure the oil 
pressure. 

Min. oil pressure:6. 400 kPa (928 psi) 

If the power steering pump assembly leaks are 
damaged due to low oil pressure, replace the power 
steering pump assembly damaged. Refer to 7.2.8.10 
replacement of power steering pump assembly. 

If the hydraulic oil path of the power steering system 
leaks, repair the hydraulic pipeline or replace the 
relevant parts. Refer to 7.2.8.6 Replacement of power 
steering Inlet and outlet oil pipe. 

NL07-0008b

Notes: 

The duration of the steering wheel in the steering limiting position does not exceed 5s; otherwise, the steering 
pump may be damaged.

7.2.8.4 Steering force inspection 

Warning! 

Warning: Refer to Warning for battery disconnection in Warnings and precautions. 

1. 

Stop the vehicle on flat rod, and make the vehicle wheel point to right front. 

2. 

Disconnect the battery negative cable. Refer to Battery Cable Disconnection/Connection Procedures. 

Notes: 

Wait at least 60 s after disconnecting the battery cable to prevent the airbag and the safety belt pre-tensioner from 
being started. 

3. 

Dismantling of driver's side safety airbag, refer to 
Replacement of driver's side safety airbag. 

4. 

Connect the battery negative cable. 

5. 

Check whether a correct tightening torque is 
applied to the steering wheel fixing nut with a 
torque wrench. 

6. 

Start the engine and have it run in idle mode. 

7. 

Turn the steering wheel counterclockwise and 
clockwise by 90 degrees with a torque wrench to 
check the steering torque during the 
counterclockwise and clockwise rotation. 

Steering force (reference): 5.5 Nm (metric) 4.1 lb-ft 
(English system) 

Notes: 

Prior to inspection, the tire type, the tire pressure and 
the contact surface must be firstly considered. 

8. 

Disconnect the battery negative cable. 

9. 

Re-check the torque of the steering wheel fixing 
nut. 

Torque:40 Nm (Metric) 29.6 lb-ft (English system) 

10.  Install the driver's side airbag. 

11.  Connect the battery negative cable.

7.2.8.5 Steering gear tie rod ball head inspection 

1. 

For dismantling of steering tie rod, refer to 7.2.8.11 replacement of steering tie rod and ball head. 

2. 

Fixing tie rod ball head onto caliper firmly. 

3. 

Install nut onto ball head bolt. 

4. 

Shake the upper ball bolt back and forth more 
than 5 times. 

5. 

Then continuously rotate the nut cap with a 
torque wrench at a speed ranging from 2 to 
4rmp/s and read the torque for the 5th round. 

Rotational torque :1.5-3 .0 Nm (1.1 - 2.2 lb-ft) 

If the rotational torque is not within the specified 
range, replace the tie rod assembly. 

Notes: 

The method for inspecting the left and right steering 
gear tie rod ball heads is the same.
