How to Know If Your Wheel Bearings Need to Be Replaced

Wheel bearings bear the brunt of a car's weight and as such are subject to considerable stress. The bearings in late-model vehicles need to be replaced less often than in older models. Regular inspection and maintenance of wheel bearings is necessary for all vehicles. Replace them every 30,000 miles or per the manufacturer's recommendations.

Things You'll Need

• Car jack
• Safety stands

Instructions

Determine Condition

1. Listen for grinding or squealing noises while driving the vehicle. The noises will worsen as the bearing weakens. Do not ignore a noisy bearing, as it could fail without warning and the wheel could separate from the axle while driving. Sound may decrease or disappear at certain speeds.

2. Feel the quality of your steering. Old bearings can cause jerky or wandering steering and is often mistaken for alignment problems.

3. Jack up the car and wiggle each wheel with your hands. If the wheel gives too much, the bearings may be loose or need replacement.

4. Driving a vehicle through water can cause bearings to rust. Sealed bearings will not be affected, but check your older model's bearings often for damage caused by water.

Tips & Warnings

• Use jack stands to secure the vehicle after jacking it up. Jacks can kick out when checking wheel bearings.
