Product Function Description

The rear propeller shaft (part number 37110-26A00) is a critical component of your Toyota HiAce‘s drivetrain system. Its primary function is to transmit rotational power from the transmission or transfer case to the rear differential, enabling the rear wheels to drive the vehicle forward. This propeller shaft assembly connects the transmission output to the rear axle differential, transferring torque through universal joints that allow for suspension movement and driveline angle changes. For Toyota HiAce models equipped with compatible diesel and gasoline engines, a properly functioning rear propeller shaft is essential for smooth power delivery, vibration-free operation, and reliable vehicle performance.

Common Symptoms of a Failing Propeller Shaft

If you are experiencing any of the following symptoms, your rear propeller shaft may be failing and in need of replacement:

• Vibration during acceleration: A noticeable vibration that increases with vehicle speed, especially under acceleration – this indicates worn universal joints or an unbalanced shaft

• Clunking or knocking noise when shifting: A metallic clunk or knock sound when engaging gears or accelerating/decelerating – this suggests worn universal joint bearings or splines

• Squeaking or chirping noise from underneath: A rhythmic squeak or chirp that changes with vehicle speed – this indicates dry or worn universal joint bearings

• Vibration that worsens at specific speeds: A vibration that is most noticeable at certain speed ranges – this suggests the shaft may be bent or the balance weights have been lost

• Visible damage or rust on the shaft: Inspection reveals dents, deep rust, or damage to the shaft tube or universal joints

• Grease leakage from universal joints: Visible grease around the universal joint caps – this indicates worn seals or damaged joint components

If you have confirmed these symptoms through inspection, replacing the rear propeller shaft is the recommended solution.

How to Diagnose a Faulty Propeller Shaft

Before purchasing a replacement, perform these simple checks to confirm the propeller shaft is the issue:

• Visual Inspection: With the vehicle safely lifted, inspect the propeller shaft for dents, deep rust, or damage. Check the universal joints for grease leakage or excessive play.

• Universal Joint Play Test: Grasp the propeller shaft near each universal joint and attempt to rotate it back and forth. Excessive play or movement indicates worn universal joint bearings.

• Vibration Road Test: Drive at various speeds and note the speed range where vibration is most noticeable. Vibration that changes with speed and is felt through the floor or seats often indicates a propeller shaft issue.

• Runout Check: Use a dial indicator to measure shaft runout while rotating the shaft. Excessive runout indicates a bent shaft or worn universal joints.

DIY or Professional Installation?

This replacement is suitable for DIY if:

• You have experience servicing drivetrain components on rear-wheel drive vehicles.

• You have access to a torque wrench, jack stands, and basic hand tools.

• You can safely lift and support the vehicle on level ground.

We recommend professional installation if:

• You are unfamiliar with propeller shaft removal and installation.

• You lack the proper tools for universal joint and flange bolt removal.

• You are not confident in torquing driveline fasteners to specification or checking driveline angles.

Note: Improper installation can lead to drivetrain vibration and safety issues. After installation, verify that all fasteners are torqued to specification. Check for proper universal joint articulation and shaft balance. A road test should be performed to verify vibration-free operation.

Component Location & Core Function

Location: The rear propeller shaft is located underneath the vehicle, running longitudinally from the transmission or transfer case output (front) to the rear differential input (rear). It sits between the transmission extension housing and the rear axle differential, supported at the rear by the differential pinion flange.

Connections: The front end of the propeller shaft connects to the transmission or transfer case output shaft via a universal joint and slip yoke or flange. The rear end connects to the rear differential pinion flange via a universal joint and flange. The universal joints allow the shaft to transmit power while accommodating suspension movement and changes in driveline angle.

Core Function: The rear propeller shaft serves as the primary link in transmitting rotational power from the transmission to the rear differential. It must handle high torque loads while maintaining balance and smooth rotation. The universal joints at each end allow the shaft to articulate as the rear suspension moves, ensuring power delivery is maintained without binding. The slip yoke (if equipped) allows for changes in driveshaft length as the suspension compresses and extends.

Common Misconceptions About Propeller Shafts

Myth 1: A propeller shaft rarely needs replacement.
Fact: Propeller shafts wear over time, especially universal joints and splines. On high-mileage or commercial vehicles, the universal joints can develop play and cause vibration that requires shaft replacement.

Myth 2: Any propeller shaft will fit.
Fact: Propeller shafts are vehicle-specific and must match the transmission output, differential pinion flange, and length requirements. This shaft is specifically designed for compatible Toyota HiAce applications.

Myth 3: Vibration is always a wheel balance issue.
Fact: Vibration that increases with speed and is felt through the floor or seats can be caused by a worn propeller shaft, not just wheel imbalance. A driveline inspection should be performed.

After Replacement Still Having Issues?

Replaced the propeller shaft but still having issues? Check these:

1. Were the matchmarks aligned? – Incorrect phasing causes vibration 

2. Was the center bearing installed correctly? – Drain hole must face downward 

3. Were the flange bolts torqued correctly? – Loose bolts cause vibration and safety risk 

4. Was the joint angle checked? – Incorrect angle causes vibration 

5. Is the transmission rear seal leaking? – Seal damage causes oil loss 

6. Are the balance weights present? – Missing weights cause vibration 

7. Is the differential pinion bearing worn? – Worn bearing causes vibration and noise 

Quality Assurance & Service Commitment

Quality Assurance:
Every component is manufactured under controlled production processes to ensure consistent dimensional accuracy and material integrity. Each unit undergoes the following quality checks before packaging:

• Dimensional inspection – critical dimensions, flange bolt pattern, and spline count are verified against design specifications

• Balance test – shaft assembly is dynamically balanced for smooth operation

• Universal joint inspection – bearing caps are checked for smooth rotation and proper fit

• Surface finish inspection – tube surface and flange faces are visually verified

Packaging Protection:
Each propeller shaft is individually sealed in protective packaging to prevent contamination and physical damage during storage and transit. The packaging includes a clear part number label for easy identification.
