Core Models: Mitsubishi Triton / L200 / Strada (all-new generation, mainly the fully redesigned MV series pickups launched in 2024–2025 and later).

Engine Compatibility: Models equipped with the 2.4L (4N16) high-output turbocharged diesel engine, in either 2WD or 4WD configurations.

DIY Diagnosis Guide

How to Tell If Your Rear Axle Shaft Bearing Case Needs Replacement:

Look for these common signs:

1. Humming or grinding noise from rear – Abnormal noise that changes with vehicle speed

2. Rear wheel wobble or vibration – Excessive movement or vibration felt through the vehicle

3. Oil leakage at rear axle – Gear oil visible around the rear wheel or brake area

4. Uneven tire wear – Abnormal wear patterns on rear tires

5. Axle shaft axial play – Excessive movement when checking axle shaft end play

💡 Quick inspection: Raise the rear of the vehicle and check for play in the rear wheels by rocking them. Inspect the rear axle area for oil leakage. A dial indicator can be used to measure axle shaft axial play—exceeding the limit indicates bearing or case wear .

General installation reference (always follow vehicle-specific service manual):

Important:

• Always use a proper bearing press – Do not hammer the bearing into place.

• Replace the bearing retainer ring – This is a non-reusable part .

• Check axle shaft for wear or damage before installing the new case.

• Use new oil seals – Replace whenever the axle shaft is removed.

• If you are unsure about any step, consult a qualified mechanic.

Installation Tips & Common Mistakes

The Mistake When Replacing a Rear Axle Shaft Bearing Case:

❌ Wrong: Reusing the bearing retainer ring or failing to check axle shaft axial play after installation.

✅ Correct:

1. Always replace the bearing retainer ring – This is a non-reusable part that secures the bearing on the axle shaft .

2. Use a proper bearing press – Hammering damages the bearing and case.

3. Check axle shaft axial play – After installation, verify the play is within the limit (0.8 mm) .

4. Inspect the axle shaft – A worn or damaged shaft will damage the new bearing and case.

5. Replace oil seals – Always use new oil seals when reassembling.

⚠️ Remember: The bearing retainer ring secures the bearing on the axle shaft. If it fails, the axle shaft can slide out of the axle housing during driving, causing loss of wheel and a serious safety hazard .

Installation Position & Core Function

The rear axle shaft bearing case (3711A563) is mounted on the rear axle shaft, inside the rear axle housing of the Mitsubishi Triton (MV platform, 2023+). It sits between the rear axle shaft and the axle housing tube, securing the rear axle shaft bearing in its correct position .

Core Functions:

1. Bearing Retention: The bearing case holds the rear axle shaft bearing in position on the axle shaft, preventing axial and radial movement .

2. Axle Shaft Support: The case supports the rear axle shaft within the axle housing, maintaining proper alignment and allowing smooth rotation.

3. Seal Support: The case provides a mounting surface for the rear axle oil seal, which prevents gear oil from leaking out of the axle housing .

4. Load Distribution: The case helps distribute the weight of the vehicle and loads from the axle shaft to the axle housing.

Note: Bearing, oil seal, and retainer ring are typically not included. Confirm with your specific seller.

After Replacement Still Having Issues?

Replaced the bearing case but still having issues? Check these:

1. Was the bearing retainer ring replaced? – Reusing the retainer ring can cause axle shaft to slide out 

2. Was the axle shaft axial play checked? – Should be within 0.8 mm limit 

3. Was the bearing installed correctly? – Improper pressing damages the bearing

4. Was a new oil seal installed? – Used seal causes oil leakage

5. Is the axle shaft worn? – A worn shaft damages the new bearing and case

6. Was the bearing preload shim installed? – Missing shim causes incorrect bearing preload 

7. Is the differential oil level correct? – Low oil causes bearing failure
