Hitting a pothole can damage wheel bearings. Basically, the force of the impact causes the ball bearings to get driven into the bearing race and cause indentations in the race. Then the bearing eventually becomes noisy. You could have damaged the bearing but the other noises (loud banging, as you describe it) and the binding of the axle may indicate other or additional damage. The only way to identify the damage, and determine the cause of the axle binding, is to inspect what you have. If you request a suspension inspection a certified mechanic will inspect the car and estimate the required repairs.

A bad wheel bearing can cause damage to other components of your vehicle, such as the CV Axle Shaft.
To tell the difference between a bad wheel bearing and a bad CV joint, listen to the noise. If you hear a grinding, growling, or rumbling noise coming from the affected wheel, it`s a bad wheel bearing. If you hear a clicking noise coming from the affected wheel when turning, it`s a bad CV joint.
If you drive a car with a damaged CV, the joint will deteriorate more, making driving impossible. You`ll be at risk of getting into an accident. In summary, it is advisable to neve drive a vehicle with faulty CV joints.
When your CV joints are not well-lubricated, the friction increases, preventing your CV axle from freely rotating. If your CV joints are not adequately lubricated, they may make noise when the axle begins to turn.
A broken axle shaft will require a serious repair. If your axle shaft breaks, it can cause all sorts of problems for your transmission system.
Since wheel bearings are what your tires spin on, they can reduce your acceleration as they fail. Due to poor lubrication or rust, wheel bearings can start to perform worse, and they won`t let your vehicle acceleration freely.
When the CV joint becomes damaged or worn, you may hear a clicking, clunking or popping sound coming from this area as the weight of the vehicle puts pressure on this area and shifts back and forth and side to side.
When a front CV axle goes bad, it will make a clunking noise as you make a slow turn. When a rear axle goes bad, the clunking or moaning sound will be in the back.
Bumpy ride
A CV axle is supposed to work smoothly with suspension movements while the wheels turn. A bad CV axle may not be able to cope with modulations in the suspension resulting in an uneven ride. Worn bearings will cause the CV axle to rotate unevenly resulting in a bumpy ride.
Things that can break your vehicle`s axle include poor maintenance; an auto accident; hitting curbs, potholes, or bumps too hard; and overloading your vehicle beyond its weight-bearing capacity. The axle is responsible for transferring the engine`s power and transmission`s torque to the wheels.
Driving with worn wheel bearings can cause serious damage to your drive-axle and steering assembly and ultimately be a major safety hazard. Driving on a bad wheel bearing puts stress on the hub and CV joint, brake system components, and ultimately on the transmission itself.
Faulty wheel bearings can cause a vibration in your steering. It could also cause the vehicle to pull more toward one side. The steering feels “loose.” A broken wheel bearing will cause the steering to have a little more play which means it will feel looser.
Impact damage or poor road quality – all impacts from driving through a pothole, driving over speed bumps or hitting the curbstone can damage a wheel bearing and reduce its lifespan. Poor quality wheel bearing – a wheel bearing is continuously under enormous pressure.
Q: Is it safe to drive with a bad wheel bearing? A: No. It can, in fact, be very dangerous to drive if one of your bearings is worn out, especially since it may cause the wheel to stop while driving. Additionally, a damaged wheel bearing puts a lot of stress on the hub, the CV joint, and the transmission itself.
The most common and often most-identifiable symptom associated with a bad wheel bearing is noise coming from the wheel or tire area of the moving vehicle. You may mistake this as engine noise, but when you listen closely you are likely to hear grinding or grating that gets louder as the vehicle accelerates.
Damaged CV joints can produce suspension vibration in your car, and will need to be replaced. In fact, if you drive for too long with faulty CV joints, you may need to replace your drive axles too, which will cost you significantly more.
Popping or clicking noises when turning.
This indicates a worn or damaged outer CV joint. To verify this condition, place the vehicle in reverse, crank the steering wheel to one side and drive the vehicle backward in a circle (check the rearview mirror first!).
That clunking noise you hear from the front end of your car when driving over a bump can be telling of an issue with your car`s suspension. More specifically, the problem is with your control arms or suspension system struts. This damage can occur if you are off-road or roughly going over potholes.
This symptom typically happens when you have a suspension issue, and occurs when driving over bumps, uneven surfaces, debris, potholes, and more. It could be that some suspension part is loose or broken. The suspension system is fairly complex, so finding the exact source of the noise can be tricky to do by yourself.
The play in the CV Axle joint causes the vibrations as the joint rotates thousands of times a minute. The rotation causes the joint to move inside the housing and bounce around accelerating the failure and causes the vibration you feel as your drive on the highway.
The most common failure pattern for wheel bearings is for those on the passenger side of the vehicle to fail first. The passenger side bearings are exposed to the most standing water in the gutter.
A sure sign that your bearing has failed is vibration. If the raceway surface of the bearing becomes damaged by abrasion, the rolling elements (the balls or rollers) will bounce around on the raceway surface during operation, causing high levels of vibration.
The bearings won`t allow the wheel to turn freely, which exacerbates the problem. It also puts stress and strain on the hub, the CV joint, the axle, and the transmission. Ultimate damage: If you don`t replace a damaged wheel bearing before it fails completely, the wheel will completely seize up.
