FORD KUGA 2011.0MY WORKSHOP REPAIR MANUAL

Before conducting a vehicle test to identify a NVH
concern carry out the following checks.
1. Check the tire pressures and adjust tospecification, as necessary.
2. Make sure the steering system fluid is correct, the system is free of leaks and is operating
correctly.
3. Make sure the vehicle steering system temperature is the same as described at the
customer interview.
4. All evaluations must take place in a relatively quiet location.
5. The heating - air conditioning (A/C) fan and radio must be turned off during evaluations and
the windows closed.Symptom Chart
Power Steering Moan Noise
Test Condition
Listen for steering moan noise with the vehicle
parked, transmission in neutral and all windows
closed in the following test conditions.
1. Engine speed at idle with no steering action.
2. Engine speed at idle with slow 90 degrees persecond turning of the steering wheel.
3. Engine speed at 1250 +/- 50 rpm with no steering action.
4. Engine speed at 1250 +/- 50 rpm with slow 90 degrees per second turning of the steering
wheel.
Action
Possible Sources
Symptom
• CHECK the routing of thepower steering lines.
• CHECK the power steering line clamps are secure.
• CHECK the power steering lines for clearance from the
vehicle body, front axle cross-
member and steering gear.
Power steering lines.
Power steering system moan
noise – A continuous low pitched
humming noise occurs when the
steering wheel is turned and the
steering system is loaded. Noise
frequency changes with engine
rpm changes. Particularly
annoying at lower engine speed. FLUSH the power steering
system.
REFER to:
Power Steering
System Flushing (211-00
Steering System - General
Information, General Proced-
ures).
Incorrect power steering fluid.
Pressure pulses from the power
steering pump. Certain amount
of noise level acceptable, not a
safety critical item.
Power steering pump.
Power Steering Whine Noise
Test Condition
Listen for steering whine noise with the vehicle
parked, transmission in neutral and all windows
closed in the following test conditions. 1. Engine speed at 1800 +/- 50 rpm with no
steering action.
2. Engine speed at 1800 +/- 50 rpm with slow 90 degrees turning of the steering wheel.
3. Engine speed at 3000 +/- 50 rpm with no steering action.
4. Engine speed at 3000 +/- 50 rpm with slow 90 degrees turning of the steering wheel.

Pinpoint Tests
NOTE:
These Pinpoint Tests are designed to take
the technician through a step-by-step diagnosis
procedure to determine the cause of a condition.
It may not always be necessary to follow the chart
to its conclusion. Carry out only the pinpoint test steps necessary to correct the condition. Then
check the operation of the system to make sure
the condition has been corrected.
After verifying that the condition has been
corrected, make sure all components removed
have been installed.
