Awaken Your G35: A Comprehensive Guide to Rear Wheel Bearing Mastery
Introduction
Your G35, a testament to engineering brilliance, deserves unwavering performance. Among its intricate components, the rear wheel bearings play a pivotal role in ensuring a smooth and safe driving experience. In this comprehensive guide, well delve into the world of G35 rear wheel bearings, empowering you with the knowledge to keep your vehicle in pristine condition.
What is a Rear Wheel Bearing?
Imagine the wheels of your G35 as spinning tops, supported by a hub that connects to the axle. The rear wheel bearing is a crucial component within this hub, acting as a bridge between the moving wheel and the stationary axle.
Types of Rear Wheel Bearings
G35s primarily utilize two types of rear wheel bearings:
* Ball Bearings: Comprising a row of steel balls held in place by inner and outer rings, ball bearings excel at handling radial loads (forces perpendicular to the axle).
* Roller Bearings: Featuring rollers instead of balls, roller bearings are better suited for axial loads (forces parallel to the axle) and higher load capacities.
Signs of a Failing Rear Wheel Bearing
Neglecting a failing rear wheel bearing can lead to costly repairs and safety hazards. Recognizing its early signs is essential:
* Humming or Grinding Noise: A distinct humming or grinding sound emanating from the rear wheels, particularly during cornering, is a telltale sign.
* Loose or Wobbly Wheel: If the wheel appears loose or wobbles excessively, it could indicate a worn bearing allowing play in the assembly.
* Increased Tire Wear: A failing bearing can misalign the wheel, leading to uneven tire wear patterns.
* Vibration: As the bearing deteriorates, it can cause vibrations that transmit through the steering wheel and chassis.
Causes of Rear Wheel Bearing Failure
Understanding the root causes of rear wheel bearing failure empowers you to mitigate its occurrence:
* Excessive Load: Overloading your G35 or frequently driving on rough roads can impose excessive stress on the bearings.
* Contamination: Dirt, debris, or water entering the bearing can accelerate wear and corrosion.
* Lack of Lubrication: Insufficient lubrication starves the bearing of essential oil, leading to friction and premature failure.
* Faulty Installation: Improper installation during replacement can compromise the bearings integrity.
Consequences of Ignoring a Failing Rear Wheel Bearing
Turning a blind eye to a failing rear wheel bearing is a dangerous gamble:
* Catastrophic Failure: If left unattended, the bearing can seize, causing the wheel to lock up and destabilizing the vehicle.
* Safety Hazard: A sudden bearing failure can lead to loss of control, increasing the risk of accidents.
* Expensive Repairs: Ignoring the problem can result in more extensive and costly repairs, including replacing the hub assembly.
Story Case: A Lesson Learned
A G35 owner ignored the humming noise from his rear wheels, attributing it to worn tires. As the noise persisted, so did his complacency. One fateful day, the bearing catastrophically failed, locking the rear wheel and sending the car into a spin. Luckily, no one was injured, but the driver was left stranded with a sizeable repair bill.
DIY Rear Wheel Bearing Replacement
Replacing a rear wheel bearing is a challenging task, recommended for experienced mechanics. If youre up for the DIY challenge, follow these steps:
* Gather Tools and Parts: Acquire the necessary tools, including a torque wrench, ball joint separator, and new rear wheel bearings.
* Safety First: Park your G35 on a level surface and engage the parking brake. Place wheel chocks behind the opposite wheels.
* Remove the Wheel: Use a lug wrench to loosen and remove the lug nuts. Lift the car using a jack and secure it with jack stands. Remove the wheel.
* Disconnect the Brake Caliper: Detach the brake caliper from the hub assembly and secure it out of the way using bungee cords.
* Remove the Brake Rotor: Remove the retaining screw and slide the brake rotor off the hub.
Story Case: A Mechanics Humor
A mechanic once quipped, "Replacing rear wheel bearings is like changing a diaper – its a messy job, but its gotta be done."
Conclusion
By heeding the signs, understanding the causes and consequences, and taking proactive maintenance measures, you can ensure that your G35s rear wheel bearings remain in optimal condition. Remember that early detection and prompt repair are crucial for a safe and trouble-free driving experience.
