Propeller Shaft - Except Lancer Evolution Mitsubishi Lancer Evolution X

GENERAL INFORMATION

The propeller shaft has the following features

1. The 3-piece, 4-joint type propeller shaft with a center bearing is adopted.
2. For the joint Nos. 1, 2, and 4, the caulking type universal joint with excellent properties of balance accuracy is equipped.
3. For joint No. 3, the lightweight and compact LJ (Lebro Joint) is equipped.
4. The dual anti-vibration construction is located at the center bearing to vehicle body joint, reducing vibration (gear noise).
5. The heat protector is adopted to the center bearing bracket.
6. The lead-free grease is adopted for the universal joint and LJ (Lebro Joint).

INTRODUCTION TO PROPELLER SHAFT DIAGNOSIS

If an abnormal noise is heard from the propeller shaft while driving, some parts of the propeller shaft may be worn or damaged, or some mounting bolts may be loose.

PROPELLER SHAFT DIAGNOSTIC TROUBLESHOOTING STRATEGY

Use these steps to plan your diagnostic strategy. If you follow them carefully, you will be sure that you have exhausted all of the possible ways to find a propeller shaft 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

SYMPTOM CHART

DIAGNOSIS

1. STEP 1. Check if the propeller shaft flange yoke and rear differential connecting nuts and the center bearing mounting nuts are loose. Propeller shaft flange yoke and rear differential connecting nuts tightening torque: 54 ± 5 N.m (40 ± 3 ft-lb) Center bearing mounting nuts tightening torque: 41 ± 5 N.m (30 ± 3 ft-lb) Q: Are the connecting nuts and mounting nuts tightened to the specified torque? YES: Go to Step 2. NO: Tighten the connecting nuts and mounting nuts to the specified torque. Then go to Step 3 .
2. STEP 2. Check the sleeve yoke's spline of front propeller shaft for wear. Q: Is wear apparent? YES: Replace the propeller shaft. Then go to Step 3. NO: Go to Step 3.
3. STEP 3. Retest the system. Q: Is the abnormal noise eliminated? YES: The procedure is complete. NO: Recheck from Step 1 .

Scheme 2

1. STEP 1. Check the propeller shaft run-out. Remove the propeller shaft. (Refer to «PROPELLER SHAFT»(/mitsubishi/lancer-evolution/x-2007-2016/remont/driveshaft-universal-joints/#propeller-shaft-except-lancer-evolution) .) Measure the propeller shaft runout. Limit: 0.5 mm (0.02 inch) Q: Is the measured value within the limit? YES: Go to Step 2. NO: Replace the propeller shaft. Then go to Step 2.
2. STEP 2. Retest the system. Q: Is the abnormal noise eliminated? YES: The procedure is complete. NO: Recheck from Step 1 .

Scheme 4

1. Place the gearshift lever to the "N" position.
2. Check the propeller shaft for dent, damage or crack.
3. Check the propeller shaft universal joint, oil seal for crack or damage. If abnormality is recognized, replace the propeller shaft with a new one.

Scheme 5

1. Place the gearshift lever to the "N" position.
2. Hold the tube of propeller shaft by one hand, and apply force by the other hand to the flange yoke or sleeve yoke in rotating direction, axial direction, and perpendicular direction for checking looseness. If looseness is recognized, replace the propeller shaft with a new one.

Scheme 6

1. Place the gearshift lever to the "N" position.
2. Make phase alignment marks on the flange yoke and differential companion flange and disconnect the flange yoke.
3. Hold the tube of propeller shaft by one hand, and apply force by the other hand to the flange yoke in flection direction for checking flection. If showing a sign of catch in the flection direction is recognized, replace the propeller shaft with a new one.
