2012 Nissan Altima Wheel Bearing: Everything You Need to Know

Introduction

The wheel bearing is a crucial component in your car's suspension system. It allows the wheels to rotate smoothly and freely, reducing friction and wear. A faulty wheel bearing can lead to a variety of problems, including noise, vibration, and reduced handling. In this article, we will take a comprehensive look at the 2012 Nissan Altima wheel bearing, including its purpose, signs of failure, and replacement procedures.

Purpose of the Wheel Bearing

The primary purpose of a wheel bearing is to support the weight of the vehicle and reduce friction between the wheel and the axle. It consists of two rows of precision bearings, housed within a metal hub. These bearings allow the wheel to rotate smoothly and freely, minimizing resistance and ensuring a comfortable ride.

Signs of a Failing Wheel Bearing

Several signs indicate a failing wheel bearing in your 2012 Nissan Altima:

• Noise: The most common symptom of a faulty wheel bearing is a grinding or humming noise that increases in intensity with speed.
• Vibration: You may feel vibrations in the steering wheel or floorboard when driving, especially at higher speeds.
• Reduced handling: A worn wheel bearing can affect the vehicle's handling, causing it to pull to one side or feel unstable when cornering.
• Increased tire wear: A faulty wheel bearing can cause uneven tire wear, leading to premature replacement.

Replacement Procedures

Replacing a wheel bearing is a complex task that requires specialized tools and experience. It is recommended to consult a qualified mechanic for professional assistance. The steps involved in replacing a wheel bearing typically include:

1. Removing the tire and brake caliper.
2. Dismantling the wheel assembly to access the bearing.
3. Removing the old bearing and pressing in the new one.
4. Reassembling the wheel assembly and tightening all components to specifications.
5. Reinstalling the tire and brake caliper.

Why Wheel Bearing Maintenance Matters

Ignoring a failing wheel bearing can lead to severe consequences, including:

• Safety hazards: A worn wheel bearing can compromise the vehicle's handling and increase the risk of accidents.
• Costly repairs: If left unattended, a faulty wheel bearing can damage other components in the suspension system, resulting in expensive repairs.
• Reduced vehicle value: A vehicle with a known wheel bearing issue will have a lower resale value.
