Wheel bearings are crucial parts of a car's frame, steering, and automatic braking. The hub, suspension components, ABS wheel speed sensor, and attaching flange are all included in the one-piece hub assembly, which is situated here between the driveshaft as well as the brake discs or drums. It is the element that enables a wheel to rotate. The bearings are closely arranged inside a metal ring that is grease-filled, watertight, and sealed. Each wheel contains this enclosure, known as a race, which is found inside the hub. Wheel bearings are designed to sustain the entire weight of the vehicle, which is a herculean task.
A wheel bearing has a life expectancy of how long?
Wheel bearings are theoretically engineered to last the life of the vehicle. There is no maintenance schedule for replacing wheel bearings, and there is no constant source of lubrication. However, they can be damaged. They are especially vulnerable if you hit a pothole, a tall curb, or a speed bump at a brisk speed.
If water, mud, road salt, or sand gets past the seal and touches the bearings, it will contaminate the grease, causing the bearings to wear down, eventually leading to fail prematurely. Also, ignoring worn-out wheel bearings can damage the vehicle’s constant velocity joint (CV joint) or automatic transmission. The outer CV joint attaches the driveshaft to the wheels, and the inner CV joint connects to the transmission. Find a reputable service technician for advice.
Warning: Custom Wheel and Tire
Another thing is to exercise caution when making modifications to your vehicles. Your vehicle's original equipment bearings were designed to withstand particular stresses. Although tires with lower tread walls and those that are broader and wider seem nice, they put more strain on the wheel bearings and may cause them to wear out more quickly. When it comes to replacements, abide by an automaker's requirements.
How Much Does a Wheel Bearing Replacement Cost?
Last but not least, replacing a single front-wheel hub assembly might cost a lot of money. The make and model of the car, the labor cost at the shop, and the price of the parts are some of the variables. Without taxes, the average out-the-door cost is roughly $350; however, repairs on luxury brands are more expensive. It is not required to replace the bearings in the additional wheel within the same spindle if the bearing in one wheel fails. Don't let anyone pressure you into doing labor that is not necessary. Find out how much it will cost to replace the wheel bearings on the car of your brand and model.
Top Warning Signs You Should Replace Your Wheel Bearings
1. Humming Sound
The most obvious and typical aural sign of damaged wheel bearings is present. But it can be perplexing. For instance, other problems like worn tyres or a bad CV joint may be the cause of a humming noise.
2. Squeaking and growling
Wheel bearings that are worn out frequently make squealing or snarling noises. As the vehicle's speed rises, the noise becomes more intense. Try to locate the source of the noise because that will show you where the worn-out wheel bearings are.
3. Three. Clicking Noise
There might be an issue with the wheel hub assembly if you hear a clicking noise that gets louder as the car speeds up.
4. Disparate Tire Wear
It may indicate worn wheel bearings if one tyre degrades more quickly than the others. However, it could also be an indication that the tyres are misaligned, the air pressure in the tyres is too high or too low, or that the vehicle's suspension parts are broken or worn out.
5. Wheel Sway
By hoisting the car, technicians can manually look for wheel movement to check for wheel wobble. It wouldn't be feasible to shake the wheel and tyre normally. If it does move, though, the hub component needs to be fixed right away. If the problem is not fixed, the tyre or wheel could conceivably separate from the car at any moment and any speed.
6. ABS Error
The warning light for anti-lock brakes can come on. The wheel's speed sensor is no longer functioning correctly if the ring, tyre, and wheel wobble, and the ABS may act intermittently or not at all. For repairs, consult a pro.
