INTRODUCTION TO POWER STEERING DIAGNOSIS

Hydraulic power steering is used for all vehicles. Faults in the power steering can include excessive play of the steering wheel, difficult steering wheel operation, noise, vibration, and oil leaks, etc. Possible causes of these faults can include defects in the gear box, oil pump or steering linkage.

POWER STEERING DIAGNOSIS TROUBLESHOOTING STRATEGY

Use these steps to plan your diagnostic strategy. If you follow them carefully, you will be sure that you have exhausted most of the possible ways to find a power steering fault.

  1. Gather information from the customer.
  2. Verify that the condition described by the customer exists.
  3. Find the malfunction by following the SYMPTOM CHART.
  4. Verify malfunction is eliminated.

SYMPTOM CHART

DIAGNOSIS

  1. STEP 1. Check for looseness at the steering shaft coupling section and at the steering wheel linkage. Q: Is there any looseness? YES: Repair or replace the part. Then go to Step 3 . NO: Go to Step 2.
  2. STEP 2. Check the steering wheel free play. With the engine running (hydraulic operation), set the front wheels straight ahead. Measure the play on the steering wheel circumference before the wheels start to move when slightly moving the steering wheel in both directions. Limit: 30 mm (1.2 inch) or less If the free play exceeds the limit value, set the steering wheel straight ahead with the engine stopped. Load approximately 5 N (1.1 pound) towards the steering circumference and check the play. Standard value (steering wheel free play with engine stopped): 16.5 mm (0.65 inch) or less Q: Does the play exceed the standard value? YES: Remove the steering gear box (Refer to «POWER STEERING GEAR BOX AND LINKAGE»(/mitsubishi/lancer-evolution/x-2007-2016/remont/manual-power-steering/#power-steering-except-lancer-evolution) ) and check the total pinion torque (Refer to «POWER STEERING GEAR BOX AND LINKAGE»(/mitsubishi/lancer-evolution/x-2007-2016/remont/manual-power-steering/#power-steering-except-lancer-evolution) ). Then go to Step 3. NO: Go to Step 3.
  3. STEP 3. Check the steering wheel play. Verify that the steering wheel play is not excessive. Q: Is the steering wheel play excessive? YES: Repeat from Step 1 . NO: The procedure is complete.

STEERING COLUMN SHAFT ASSEMBLY SHOCK ABSORBING MECHANISM CHECK

WARNINGIf the vehicle continues to be driven after the collision absorbing mechanism has operated, the steering column shaft may be damaged while it is in use. If there is a slack in the mounting base, do not attempt to repair it. Replace the steering column shaft assembly.

If a collision accident occurs or severe impact is applied on the steering wheel, the collision energy absorbing mechanism may have operated. Once the mechanism has operated, it will be inoperative even if it has suffered no apparent damage. Determine if the steering column shaft can be reused by the following procedure. If the collision energy absorbing mechanism has already operated, replace the steering shaft assembly (Refer to STEERING COLUMN SHAFT ASSEMBLY ). If any excessive radial free play on the steering wheel is found with the tilt lever in the lock position, always inspect the steering shaft assembly.

Scheme 42

Scheme 42: INSPECTION PROCEDURE
  1. Remove the lower and upper column covers. CAUTION: After inspection, do not release the tilt lever until the steering shaft assembly has been installed.
  2. Ensure that the tilt lever is in the lock position.
