Inspecting your vehicle’s wheel bearings is an important maintenance task that can prevent costly repairs and ensure your safety on the road. Properly jacking up your vehicle is the first step in this process. Follow these guidelines to do it safely and effectively.
Preparing to Jack Up Your Vehicle
Before lifting your vehicle, gather the necessary tools:
- A hydraulic or scissor jack
- Jack stands rated for your vehicle’s weight
- Wheel chocks
- Gloves and safety glasses
- A tire iron or lug wrench
Ensure your vehicle is on a flat, stable surface. Engage the parking brake and put wheel chocks behind the wheels that will remain on the ground to prevent rolling.
Positioning the Jack
Locate the manufacturer’s recommended jacking points, usually indicated in your vehicle’s owner manual. These points are reinforced to handle the weight when lifted. Position the jack securely under these points.
Gently raise the vehicle until the wheel you want to inspect is slightly off the ground. Do not lift the vehicle too high at this stage; just enough to remove the wheel if needed.
Using Jack Stands for Safety
Once the vehicle is raised, place jack stands under the vehicle’s frame or designated support points. Carefully lower the vehicle onto the stands, ensuring it is stable before proceeding.
Never rely solely on the hydraulic jack to hold the vehicle. Always use jack stands for safety.
Inspecting the Wheel Bearings
With the vehicle securely supported, remove the wheel. Rotate the hub manually to check for smoothness or any grinding noises. Wiggle the hub to detect looseness, which may indicate bearing wear.
Look for signs of damage, such as uneven wear, corrosion, or leaks around the bearing area. If needed, consult a professional mechanic for further diagnosis or replacement.
Lowering Your Vehicle
After completing the inspection, carefully raise the vehicle slightly to remove the jack stands. Then, lower the vehicle slowly back onto the ground using the hydraulic jack. Remove the jack stands and ensure all tools are cleared away.
Finally, tighten the lug nuts securely and double-check your work. Your vehicle is now safely lowered and ready for regular driving.
