INSPECTION PROCEDURE 9: Vibration

Note. A slight vibration may be felt when the stationary steering effort is made due to the condition of the road surface. To check whether the vibration actually exists or not, test-drive the vehicle on a dry concrete or asphalt surface. A very slight amount of vibration is not a malfunction.

  1. STEP 1. Check for entry of air. Q: Is the power steering fluid foamy? YES: Bleed the air (Refer to «POWER STEERING SYSTEM AIR BLEEDING»(/mitsubishi/lancer-evolution/x-2007-2016/remont/manual-power-steering/#power-steering-except-lancer-evolution__power-steering-system-air-bleeding) ). Then go to Step 3 . NO: Go to Step 2.
  2. STEP 2. Check the steering gear for damage. Q: Is there damage? YES: Replace the part (Refer to «DISASSEMBLY AND ASSEMBLY»(/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. Retest the system. Confirm that no vibration is generated. Q: Is there vibration? YES: Repeat from Step 1 . NO: The procedure is complete.
  1. STEP 1. Check for loosening of the return tube flare nut. Q: Is the flare nut loose? YES: Tighten it to standard value (Refer to «POWER STEERING HOSES»(/mitsubishi/lancer-evolution/x-2007-2016/remont/manual-power-steering/#power-steering-except-lancer-evolution) ). Then go to Step 3 . NO: Go to Step 2.
  2. STEP 2. Check the hose connection and the clamp installation. Q: Are they correct? YES: Go to Step 3. NO: Repair or replace the part (Refer to «POWER STEERING HOSES»(/mitsubishi/lancer-evolution/x-2007-2016/remont/manual-power-steering/#power-steering-except-lancer-evolution) ). Then go to Step 3.
  3. STEP 3. Retest the system. Check that no oil is leaking. Q: Is there oil leakage? YES: Repeat from Step 1 . NO: The procedure is complete.
  1. STEP 1. Check the hose for damage or clogging. Q: Is the hose damaged or clogged? YES: Replace it (Refer to «POWER STEERING HOSES»(/mitsubishi/lancer-evolution/x-2007-2016/remont/manual-power-steering/#power-steering-except-lancer-evolution) ). Then go to Step 2. NO: Go to Step 2.
  2. STEP 2. Retest the system. Check that no oil is leaking. Q: Is there oil leakage? YES: Repeat from Step 1 . NO: The procedure is complete.
  1. STEP 1. Check the oil reservoir for damage. Q: Is there damage? YES: Replace the oil reservoir (Refer to «POWER STEERING HOSES»(/mitsubishi/lancer-evolution/x-2007-2016/remont/manual-power-steering/#power-steering-except-lancer-evolution) ). Then go to Step 3 . NO: Go to Step 2.
  2. STEP 2. Check for overflowing. Q: Is there oil overflowing from the reservoir? YES: Adjust fluid level. Then go to Step 3. NO: Go to Step 3.
  3. STEP 3. Retest the system. Q: Is there oil leakage? YES: Repeat from to Step 1 . NO: The procedure is complete.
  1. STEP 1. Check the oil pump body for damage. Q: Is there damage? YES: Replace the part (Refer to «REMOVAL AND INSTALLATION»(/mitsubishi/lancer-evolution/x-2007-2016/remont/manual-power-steering/#power-steering-except-lancer-evolution) ). Then go to Step 3 . NO: Go to Step 2.
  2. STEP 2. Check the O-ring or oil seal for damage. Q: Is there damage? YES: Replace the part (Refer to «REMOVAL AND INSTALLATION»(/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. Retest the system. Check that no oil is leaking. Q: Is there oil leakage? YES: Repeat from Step 1 . NO: The procedure is complete.
  1. STEP 1. Check the steering gear housing for damage. Q: Is there damage? YES: Replace the part (Refer to «DISASSEMBLY AND ASSEMBLY»(/mitsubishi/lancer-evolution/x-2007-2016/remont/manual-power-steering/#power-steering-except-lancer-evolution) ). Then go to Step 3 . NO: Go to Step 2.
  2. STEP 2. Check the oil-ring or oil seal for damage. Q: Is there damage? YES: Replace the part (Refer to «DISASSEMBLY AND ASSEMBLY»(/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. Retest the system. Check that no oil is leaking. Q: Is there oil leakage? YES: Repeat from Step 1 . NO: The procedure is complete.
