How to Change Rear Wheel Bearing Hilux: Expert Tips and Tricks

The unmistakable rumbling sound from your Hilux’s rear axle can only mean one thing – a worn-out wheel bearing. While it might seem intimidating, changing a rear wheel bearing on your Hilux is a DIY project within reach of most mechanically inclined individuals. This comprehensive guide will walk you through the process step-by-step, equipping you with the knowledge and confidence to tackle this essential maintenance task.

Assessing the Situation: Identifying the Culprit

Before diving into the repair, it’s crucial to confirm that the noise you’re hearing is indeed coming from a faulty rear wheel bearing. Here’s a simple test:

1. Jack up the vehicle and support it securely with jack stands.
2. Spin the wheel by hand. Listen carefully for any grinding or rumbling noises.
3. Check for play in the wheel by grabbing it at the top and bottom and attempting to move it side to side. If you feel excessive movement, the bearing is likely worn.

If the test confirms a faulty bearing, you’re ready to proceed with the replacement.

Gathering Your Arsenal: Essential Tools and Parts

To successfully replace the rear wheel bearing, you’ll need the following tools and parts:

• Jack and jack stands for safe vehicle lifting
• Lug wrench to remove the wheel
• Torx socket set for loosening and tightening various bolts
• Breaker bar for stubborn bolts
• Hammer and punch for removing the old bearing
• Bearing race tool for installing the new bearing race
• New rear wheel bearing (ensure you get the correct size and type for your Hilux model)
• Grease for lubricating the new bearing
• Torque wrench for tightening bolts to the correct specifications

Prepping for the Operation: A Smooth and Safe Process

1. Park on a level surface and engage the parking brake.
2. Chock the front wheels to prevent the vehicle from rolling.
3. Remove the wheel using the lug wrench.
4. Remove the brake caliper and hang it safely out of the way. Be careful not to damage the brake hose.

2. Install the new bearing race using the bearing race tool. Ensure it sits flush against the hub.
3. Pack the new bearing with grease to ensure proper lubrication.
4. Carefully press the new bearing into the hub using the hammer and punch. Avoid damaging the bearing.

Reassembly: Back to Smooth Sailing

1. Install the hub nut and tighten it to the correct torque specification using the torque wrench.
2. Reinstall the brake rotor and ensure it sits securely on the hub.
3. Reinstall the brake caliper and ensure the brake pads are properly seated.
4. Reinstall the wheel and tighten the lug nuts to the correct torque specification.
5. Lower the vehicle and remove the jack stands.

The Final Test: A Road to Success

After completing the repair, take your Hilux for a test drive. The rumbling sound should be gone, and the wheel should spin smoothly without any play. If you experience any issues, recheck your work and address any potential problems.
