Scheme 107

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) If the free play exceeds the limit value, set the steering wheel straight ahead with the engine stopped. Apply approximately 5 N (1.1 pound) in one direction and check the play. Standard value (steering wheel play with engine stopped): 10 mm (0.4 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/ix-2005-2007/remont/manual-power-steering/#power-steering-lancer-evolution) ) and check the total pinion torque (Refer to «POWER STEERING GEAR BOX AND LINKAGE»(/mitsubishi/lancer-evolution/ix-2005-2007/remont/manual-power-steering/#power-steering-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 to Step 1 . NO: The procedure is complete.

Scheme 108

1. STEP 1. Check the power steering oil pump drive belt tension. Refer to «DRIVE BELTS»(/mitsubishi/lancer-evolution/ix-2005-2007/remont/hoistjack/#general-lancer-evolution) . Q: Is the power steering oil pump drive belt tension within the standard value? YES: Go to Step 2. NO: Adjust the tension. (Refer to «DRIVE BELTS»(/mitsubishi/lancer-evolution/ix-2005-2007/remont/hoistjack/#general-lancer-evolution) ). Then go to Step 9 .
2. STEP 2. Check the drive belt for damage. Q: Is the drive belt damaged? YES: Replace the drive belt. Then go to Step 9 . NO: Go to Step 3.
3. STEP 3. Check the fluid level. Park the vehicle on a flat, level surface, and then start the engine. Turn the steering wheel several times to raise the temperature of the fluid to approximately 50 - 60° C (122 - 140° F). With the engine running, turn the wheel all the way to the left and right several times. Check the fluid in the oil reservoir for foaming or milkiness. Check the difference of the fluid level when the engine is stopped, and while it is running. Q: Is the check result OK? YES: Go to Step 4. NO: Bleed the air (Refer to «POWER STEERING SYSTEM AIR BLEEDING»(/mitsubishi/lancer-evolution/ix-2005-2007/remont/manual-power-steering/#power-steering-lancer-evolution__power-steering-system-air-bleeding) ). Then go to Step 9 .
4. STEP 4. Check each hose for crushing or twisting. Q: Is any hose crushed or twisted? YES: Repair or replace the hose. Then go to Step 9 . NO: Go to Step 5.
5. STEP 5. Check for oil leaks. Q: Are there oil leaks? YES: Repair it. Then go to Step 9 . NO: Go to Step 6.
6. STEP 6. Check the wheel alignment (camber and caster). Refer to «FRONT WHEEL ALIGNMENT CHECK AND ADJUSTMENT»(/mitsubishi/lancer-evolution/ix-2005-2007/remont/suspension-front/#front-suspension-wheel-alignment-lancer-evolution__front-wheel-alignment-check-and-adjustment) . Q: Is the alignment incorrect? YES: Repair it. Then go to Step 9 . NO: Go to Step 7.
7. STEP 7. Check the gear box rack piston seal for damage. Q: Is there damage? YES: Replace it. Then go to Step 9 . NO: Go to Step 8.
8. STEP 8. Check for excessive tie rod end ball joint breakaway torque. Refer to «TIE ROD END BALL JOINT BREAKAWAY TORQUE CHECK»(/mitsubishi/lancer-evolution/ix-2005-2007/remont/manual-power-steering/#power-steering-lancer-evolution__tie-rod-end-ball-joint-breakaway) . Q: Is there fault? YES: Replace the part. Then go to Step 9. NO: Go to Step 9.
9. STEP 9. Check the steering wheel operation. Verify that the steering wheel operation is not difficult. Q: Is the steering wheel operation difficult? YES: Repeat from Step 1 . NO: The procedure is complete.
