Get Nissan Note E12 Front Wheel Bearing DAC37720037M in Kenya
The front wheel bearing in the Nissan Note E12 is a crucial component of the vehicle’s suspension and steering system. It allows the wheels to rotate smoothly with minimal friction, ensuring stability, control, and safety while driving. Though often overlooked, a failing wheel bearing can lead to serious issues like poor handling, uneven tire wear, and even wheel detachment if not addressed in time.
1. What Is a Front Wheel Bearing?
A wheel bearing is a set of steel balls or tapered rollers held together by a metal ring (race). It sits inside the wheel hub and allows the wheel to spin freely with minimal resistance.
1.1 Role of the Front Wheel Bearing
Reduces friction between the wheel and axle.
Supports the vehicle’s weight while driving.
Ensures smooth wheel rotation for a stable ride.
Improves handling and fuel efficiency.
Works with the ABS (Anti-lock Braking System) to enhance braking performance.
Fun Fact: Wheel bearings experience intense forces when driving, often handling loads of over 1,500 kg per bearing!
2. Types of Wheel Bearings Used in the Nissan Note E12
Different types of wheel bearings are used in vehicles, and the Nissan Note E12 primarily uses sealed ball bearings.
2.1 Ball Bearings
- The most common type used in modern vehicles.
- Made of hardened steel balls inside a metal race.
- Sealed for life, meaning they don’t require lubrication.
- Quiet and durable, but susceptible to contamination when the seal is broken.
2.2 Tapered Roller Bearings
- Used mainly in heavy-duty applications like trucks.
- Designed to handle both radial and axial loads.
- Requires regular lubrication and adjustment.
- Less common in small passenger cars like the Nissan Note E12.
Tip: Always use OEM (Original Equipment Manufacturer) wheel bearings for the best fit and durability.
3. Symptoms of a Failing Front Wheel Bearing
A faulty wheel bearing can lead to serious problems. Here are the warning signs to look out for:
3.1 Unusual Noises
- A humming, growling, or roaring sound that gets louder as you drive.
- Grinding noises when turning.
3.2 Wheel Vibration & Steering Instability
- The steering wheel shakes at high speeds.
- The car feels unstable or pulls to one side.
3.3 Uneven Tire Wear
- Excessive wear on one side of the tire.
- Possible alignment issues caused by a loose bearing.
3.4 ABS Warning Light
- A failing wheel bearing affects the ABS sensor, triggering the warning light.
3.5 Excessive Play in the Wheel
- When jacked up, the wheel wobbles excessively when shaken by hand.
If you notice any of these symptoms, inspect and replace the wheel bearing immediately to prevent further damage.
4. Causes of Wheel Bearing Failure
4.1 Water & Dirt Contamination
- Sealed bearings are protected, but once the seal is broken, dirt and water enter, causing rust and wear.
4.2 Poor Road Conditions
- Hitting potholes, curbs, or speed bumps at high speeds can damage the bearing.
4.3 Overloading
- Carrying excessive weight puts more strain on the bearings, leading to premature wear.
4.4 Improper Installation
- Bearings must be installed correctly and torqued to manufacturer specifications.
4.5 Lack of Lubrication
- Though modern bearings are sealed for life, older types require regular lubrication.
Tip: Avoid driving through deep water or washing your car’s undercarriage with high-pressure water to prevent contamination.
5. How to Replace the Front Wheel Bearing in a Nissan Note E12
Replacing a wheel bearing is a technical job that requires special tools. If you’re not experienced, it’s best to take it to a mechanic.
5.1 Tools Required
Jack & jack stands
Lug wrench
Torque wrench
Socket set
Wheel bearing puller or hydraulic press
New wheel bearing (OEM recommended)
5.2 Step-by-Step Replacement Guide
Loosen the lug nuts before lifting the car.
Jack up the front of the car and secure it with jack stands.
Remove the wheel and set it aside.
Unbolt the brake caliper and hang it safely (don’t let it dangle by the brake line).
Remove the brake rotor and hub assembly.
Press out the old wheel bearing using a bearing puller or hydraulic press.
Clean the hub and install the new bearing securely.
Reassemble everything in reverse order.
Torque all bolts to spec and test drive the car.
Warning: Never use a hammer to install a wheel bearing, as it can damage the new bearing!
6. Maintenance Tips for a Longer Wheel Bearing Life
