The front passenger's side wheel started thumping when going uphill. Could it be the wheel bearing?
It could be from the bearing, or from a tire with a bubble or tread separation. I recommend having a mechanic, such as one from YourMechanic, run a diagnostic on the source of the noise in order to identify and quote the repairs needed.

When the wheel bearing in your tires is damaged or deteriorating, it produces a soft humming sound or grinding noise when you change lanes. It`s best to have the wheel bearings replaced as soon as possible to prevent excessive damage and collisions.
What causes wheel bearing noise? Over time these bearings can become loose or worn. This wear will be accelerated if the grease has leaked out or dirt, grit or water have found their way inside. The first time you may know you have a problem is at a service or MoT test.
Squealing & Growling
The classic sounds of a bad wheel bearing are cyclic chirping, squealing and/or growling noise. You can also tell that the sound is related to wheel bearings if it changes in proportion to vehicle speed. The sound can get worse with every turn, or it can disappear momentarily.
When a wheel hub bearing wears out, it puts extra stress on the CV-joint. That can cause the knocking/clunking noise when you turn the vehicle.
A worn wheel bearing can cause a howling noise. If you`re also hearing a rumbling noise when turning, then it`s likely a bad wheel bearing. You may also trace this noise to a loose pinion-bearing preload. It`s likely the case when you only hear the noise when decelerating.
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.
How can you stop a wheel bearing making noise? Unfortunately you can`t: the only solution to a worn, noisy wheel bearing is to have it replaced by a garage; bearings are not repairable.
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.
A clunking, rattling, or squeaking noise from your front end while driving can be annoying and unnerving. Oftentimes, this noisy symptom means there is a problem with your vehicle`s suspension system. These sounds typically occur when driving over uneven surfaces, bumps, or potholes.
“Womp womp” tire suspects include alignment issues, worn suspension parts, and improper tire inflation. You can solve this mystery by: Taking your vehicle in for a professional wheel alignment. Getting a safety inspection to identify parts that need replacement or repair.
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.
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.
Damaged or worn wheel bearings
Designed to secure the wheel hub to the vehicle`s suspension, and allow the wheels to turn properly, these safety critical components can cause steering wheel vibration if damaged or not lubricated sufficiently. In this instance, the steering wheel will usually only shake when turning.
Brake rotors are held in alignment by wheel bearings. If you have a faulty or loose wheel bearing, the rotor will wobble on its axis. This wobble causes the rotor to push the caliper piston into its bore (See Image 2). Now, when you hit the brake pedal, the piston has to travel farther than normal to apply the brakes.
If Only One Bearing Is Bad, Do I Have To Replace Them Both? No. Your car`s wheel bearings are entirely separate, and a failure in one bearing does not affect the others. You only need to replace the bearing that has failed.
A worn outer CV joint will produce loud clicking noises when you turn sharply. Usually, this noise will increase with acceleration. A worn inner CV joint can cause loud clunking noises when switching between drive and reverse.
If the bearing noise has been growing gradually, then without suggesting it is “okay” to drive 200 miles, the noise may just grow worse over that distance. If the bearing noise appeared out of nowhere, then that suggests an immediate failure potential and should be changed BEFORE a 200 mile drive.
1. Lubrication Failure. According to a recent study, up to 80 percent of bearing failures are caused by improper lubrication. This includes insufficient lubrication, use of improper lubricants or excessive temperatures that degrade the lubricant.
Bearings usually make a growling noise, low pitch, rises with speed. Tires can make all types of sounds and bad alignment can screw up a tire so that it is noisy when fixed. That usually goes away with time. Bearings usually get worse with time.
Did you know a spray of WD-40 Specialist White Lithium Grease is a great lithium lubricant for bearings? It reduces friction on bearings and helps keep them protected from rust as well. Simply apply by spraying directly onto the area.
A telltale sign that your vibration may be caused by a faulty CV joint is if you also hear a clicking or clunking noise when turning. Also known as engine mounts, motor mounts hold your car`s engine in place.
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.
