In a car suspension system, wheel bearings carry out two key tasks. Firstly, they help the wheels in rotating with less friction, and secondly they hold weight of the car. To perform both tasks, both front and rear bearings should be in good condition. If front wheel bearings on a hummer h2 are contaminated, the end result could even be a fatal crash; so, here are some important things to remember.

Overview

The seals should be leak free for high lubrication and send the contaminations out. In a sedan, both wheel bearings at front and rear side supports for wheel rotations and weight of car.

Usually, all wheel bearings are designed to withstand more than 150,000 miles. But, mainly the lifetime of these wheel bearings is depend on usage methods. A wheel bearing may loose its performance because of contamination, loss of grease, or maladjustments. In the wheel bearing mechanism, the seals are most susceptible parts. If once the seals are damaged (starts leaking), the wheel bearings are in danger.

Bad Consequences

A damaged or worn grease seal can permit grease to come out from the bearings and water or dirt would enter via this path to wheel bearing cavity. So, the bearings will be damaged, if not some one corrects the problem immediately.

Wheel bearings are used for two purposes both at front and rear wheel sides. These wheel bearings are fixed to all wheels of vehicle.
