Wheel bearing noise is generally a warning sign indicating that the bearing itself is malfunctioning. If a bearing is making noise it is quite possible that it may need to be replaced. Most of these parts are built to last 150,000 miles or more - they will perform the job they were designed for if properly maintained.

One of the first indications of a defective wheel bearing is noise. The sound that is created from this condition is reminiscent of a cracking sound, or a chirping sound. If you are hearing anything similar to the previously described noises, you should take it under advisement to have your mechanic take a look at your vehicle as soon as possible. If this condition is ignored it may very well be costly, or even cause an accident.

The cause of wheel bearing failure before its prescribed time frame usually occurs from a damaged grease seal, or grease leak. A damaged bearing seal can let water and dirt enter the bearing cavity, and if this happens the bearing will under go strain caused by the extreme heat generated from this condition.

Responsibility is the key to good car ownership. You can keep the cost down of prematurely replacing the bearings of your vehicle if you follow the manufactures car care guide lines. Some cars will have to have the bearings replaced before the manufactures recommended life span has ended. If this happens then it is probable that other mechanical issues are in affect.

The essential function of a bearing is to help spin the wheel while reducing friction. Friction produces heat, and if this part becomes defective that bearing will most likely begin to make noise. The heat created from this conditional malfunction has been known to seize the bearing to the spindle. If this happens, the process of removing and replacing the bearing and the surrounding components will take more time and effort, and in turn become very expensive.

Preventative maintenance is one of the most important responsibilities of a car owner. This particular noise has surprised many car owners, because they over looked the bearings. The bearings are the least thought of component of any vehicle. Good common sense if exercised can help prevent the bearings on your car from becoming defective before it is time to change them. Another preventative maintenance strategy is to clean, inspect, and grease the bearings every 30,000 miles. This can only be done if they are not factory sealed. Wheel bearing noise should not be confused with front end noise.

One more way you can practice good preventative maintenance for your cars bearing’s, and quite possibly never have to hear that dreadful noise; would be to check for wheel play yourself or have your mechanic do the checking for you on a regularly scheduled basis. Plus you can keep an open ear and listen for any noise that may come from the bearing as you drive your vehicle.
