The Ultimate Guide: How to Change Rear Wheel Bearing Toyota Yaris

Are you experiencing a persistent humming or grinding noise coming from your Toyota Yaris’s rear wheels? This could be the telltale sign of a worn-out rear wheel bearing. While a trip to the mechanic might seem like the easiest solution, changing a rear wheel bearing on your Yaris is a DIY project that can save you a significant amount of money. This guide will walk you through the process, step-by-step, empowering you to tackle this repair with confidence.

Understanding the Importance of Rear Wheel Bearings

Before diving into the replacement process, it’s essential to understand the crucial role rear wheel bearings play in your Yaris’s smooth operation. These bearings act as the foundation for your wheels, allowing them to rotate freely while supporting the weight of your vehicle.

When a rear wheel bearing fails, it can cause:

• Noise: A humming, grinding, or roaring sound, especially when driving at speed or turning.
• Vibration: A noticeable vibration in the steering wheel or throughout the car.
• Uneven tire wear: Premature wear on one or both rear tires due to misalignment caused by a faulty bearing.
• Loss of control: In extreme cases, a completely seized bearing can lead to a loss of control of the vehicle.

Gather Your Tools and Supplies

Before you begin, ensure you have the following tools and supplies:

• Jack and jack stands: For safely lifting the vehicle.
• Lug wrench: To remove the wheel.
• Torque wrench: To tighten the lug nuts to the manufacturer’s specifications.
• Hammer: To remove the old bearing.
• Bearing race and seal puller: To remove the bearing races and seal from the hub.
• Bearing race and seal installer: To install the new bearing races and seal.
• New rear wheel bearing: Ensure you purchase the correct bearing for your specific Yaris model and year.
• Grease: To lubricate the new bearing.
• Penetrating fluid (optional): To help loosen stubborn bolts.
• Safety glasses and gloves: To protect yourself from debris and potential injuries.
