How Wheel Bearings Support Your Mercury Vehicle's Weight
Wheel bearings are integral components within your Mercury vehicle's suspension system, playing a vital role in supporting its weight and making sure your Mercury operates smoothly. Wheel bearings facilitate a low-friction rotation between the stationary axle and the rotating wheel, allowing for efficient load distribution.

In a Mercury sedan like the Mercury Milan, equipped with a front-wheel-drive (FWD) configuration, wheel bearings bear the weight of the vehicle, supporting the front axle and enabling smooth wheel movement. The design of wheel bearings allows them to absorb both axial and radial loads, contributing to a comfortable driving experience by dampening vibrations and shocks from the road.

How Long does Wheel Bearing Last?
The lifespan of a wheel bearing can vary depending on several factors, including driving conditions, vehicle type, and the quality of the wheel bearing itself. Generally, a wheel bearing is expected to last between 85,000 and 100,000 miles (137,000 to 161,000 kilometers). However, it's essential to note that some may last longer, while others may fail prematurely.

Wheel Bearing Location on your Mercury
The location of the wheel bearing on a Mercury vehicle can vary depending on the specific model and year. However, in most modern vehicles, including those from the Mercury brand, the wheel bearing is part of the wheel hub assembly. The wheel hub assembly is a component that houses the wheel bearing and connects the wheel to the vehicle's suspension.

1. Front Wheel Bearing:
-For front-wheel-drive (FWD) vehicles, the front wheel bearing is typically integrated into the front wheel hub assembly.
-The wheel hub assembly is located at the center of the wheel and is mounted to the steering knuckle, which is part of the vehicle's front suspension.
-To access the front wheel bearing, you may need to remove the wheel, brake caliper, and rotor. The wheel hub assembly is then exposed, and you can inspect or replace the wheel bearing if necessary.

2. Rear Wheel Bearing:
-For rear-wheel-drive (RWD) vehicles or all-wheel-drive (AWD) vehicles, the rear wheel bearing is integrated into the rear wheel hub assembly.
-Similar to the front, the rear wheel hub assembly is mounted to the rear suspension components and is located at the center of the wheel.
-Accessing the rear wheel bearing may require removing the wheel, brake components, and potentially other suspension parts to reach the hub assembly.

How to A Broken Rack End Affect your Wheel Bearing
A broken or damaged rack end can indirectly affect the wheel bearing and other components of the vehicle's suspension and steering system. While the rack end itself is not directly connected to the wheel bearing, their interdependence within the overall system can lead to secondary issues. Here's how a broken rack end could potentially impact the wheel bearing:

-Misalignment: A broken rack end can result in misalignment of the front wheels. Misalignment puts uneven stress on the wheel bearings, causing them to wear out prematurely. Uneven pressure on the wheel bearings can lead to increased friction and heat, accelerating the deterioration of the bearing components.
-Vibrations and Forces: When the rack end is damaged, it may cause vibrations and irregular steering movements. These vibrations and forces are transmitted through the steering linkage to the wheel hub. Excessive vibrations and forces can contribute to increased wear on the wheel bearing, as the bearing is subjected to additional stress beyond normal operating conditions.
-Impact on Suspension Components: A broken rack end may impact the overall stability of the suspension.
If the suspension is compromised, it can lead to uneven loading on the wheel bearings, affecting their performance.
-Tire Wear: Uneven tire wear can, in turn, affect the load distribution on the wheel bearings. Uneven loads on the wheel bearings can lead to premature wear and failure.
