My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
Hi there. Every tire and wheel on your vehicle is secured to the wheel hub assembly. If the wheel bearings or the hub itself are damaged, then it can break, causing the wheel and tires to literally fall off your car. So, it’s pretty important to replace the wheel hub assembly if it’s damaged, not only to keep the car running, but for your safety and those on the road. But with only 46,300 miles on your car, it may be a good idea to have another mechanic give your car a second inspection to ensure the problem is with the wheel hub assembly.

A wheel hub bearing assembly usually includes manufactured Bearings, Sensors and Seals. The assembly is the collection of the different parts that gives the wheels free rotation while the bearing is the part that manages your vehicle`s weight and movement.
The cost to replace one front-wheel hub assembly varies widely. Some variables include the make and model, the garage`s labor rate and the cost for parts. The national average is about $350 to fix the wheel bearings at one wheel. As you might imagine, however, luxury brands cost more.
On each wheel, you`ll find the wheel hub assembly between the drive axle and the brake drums or discs. On the brake disc side, the wheel is attached to the bolts of the wheel hub assembly. While on the side of the drive axle, the hub assembly is mounted to the steering knuckle either as a bolt-on or press-in assembly.
Gently rock the hub assembly with one hand on the top and the other hand on the bottom. If it rocks towards the car or away from it (not left or right), then it`s loose and it needs to be replaced. If it doesn`t rock at all, move on to the next wheel.
Clicking Sound

If you hear a clicking sound that increases in frequency as the vehicle accelerates, there could be a problem with the wheel hub assembly.

Wheel Hub Assembly Failure Symptoms

A grinding noise or rumbling sound. A clicking sound during acceleration. Vibrating or loose steering wheel. Abnormal side pull during brake application.

The hub assemblies will usually have bearings in them that can wear out over time. When the car is ran, the hub assemblies will have to work to ensure that the wheels turn as they should. The wheel hub assemblies on a car are intended to last for about 100,000 miles.
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.
Ultimate damage: If you don`t replace a damaged wheel bearing before it fails completely, the wheel will completely seize up. If this happens while you`re driving, the results can be catastrophic.
A wheel hub assembly is a vital part on a vehicle, particularly in regards to how the vehicle feels while driving and how it handles. These assemblies are exactly the same as a normal wheel bearing and hub, except they can be changed out by just removing a few bolts.
There are four primary causes of hub failures. They are lack of lubrication, overloading the vehicle, installing the axle nut too tight, or installing the axle nut too loose. Usually, hub failures are progressive and will produce some evidence of the impending failure.
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.
Your wheel bearing may have been damaged slightly in the past and has now worn to the point it is starting to make noise. Your mechanic is correct in that the only repair for the bearing is to replace the hub. It is a sealed unit and cannot be disassembled without destroying it.
For new technicians, turnaround time can be up to two hours. However, that time can be cut in half by experienced technicians, especially if there are no delays in acquiring parts or tools.
You can test this by gently swaying your car while driving slowly. If the noise lessens when you sway right, then the damaged bearing is likely on a left wheel bearing. If it lessens when you sway left, a right wheel bearing is likely broken.
Another indication of a damaged wheel hub assembly is when the steering wheel vibrates at lower speeds and progressively gets worse as the car accelerates. A damaged wheel hub assembly can also cause the steering wheel to feel loose when you`re driving down the road, making turns or negotiating dips in the road.
During installation, grease is often packed into these bearings by hand. Not only should grease be packed into the bearing, but some grease should be applied to the housing and on the wheel end`s inside surfaces where the bearing sits. This will help prevent corrosion.
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.
Unless both bearings on all side of the wheels are overworked, there is no need to replace them all at once. You should only swap out the ones that need it.
It contains smaller gears that rotate inside a larger gear like the “planets” revolve around the sun. This design lessens the load while creating torque. Under normal use, I usually change the oil every two years.
Point 1 – In principle, do not reuse wheel hub bearings that have been removed. Point 2 – Thoroughly clean and grease up your bearings before you reuse them in an emergency situation. After cleaning, make sure there is no backlash.
If a wheel bearing is missing, it is not recommended you drive the vehicle at all as the wheel can fall off entirely while the vehicle is in motion. The wheel bearing is an essential part in keeping the wheel attached to your car, so without it, the wheel has nothing to hold it on.
One of the most alarming and noticeable signs of bad wheel bearings are brake issues, which can occur when your wheel bearings are worn down and loose in the housing. You may notice inefficient braking on the road, brake “slips,” or uneven wear on your brake pads.

I hear an abnormal noise from front driver’s side wheel. It sounds like a wheel bearing but not sure.
ANSWER : A wheel bearing noise can be different between vehicles as some designs may vary a little. The most common is a roaring noise that may change when going around turns. It may be louder going in one direction or the other or just make a loud noise all of the time. The wheel hub presses into the wheel bearing. The hub is where the studs are for the wheel to be bolted onto the steering knuckle and the bearing provides the support for the wheel and weight of the vehicle. Consider hiring an experienced technician like one from YourMechanic who can come out and take a closer look at your wheel bearing noise to offer a more personal diagnosis.

Do I need to replace the hubs to go back to factory wheel bolts.
ANSWER : You’re wise to go back to factory fasteners. While there are a few good quality aftermarket products out there for your car, most of the options are a kind of one-size-fits-all that involve spacers and adapters that change the design offset and lead to all kinds of suspension and wheel bearing problems. you should not need to replace the hubs as long as the threads are not damaged. It should be possible to extract the studs through conventional means. If a hub IS damaged, then there is no choice but to replace it. This will involve replacing the wheel bearing as well so it can get expensive. If this project is more than you want to take on, you can contact Your Mechanic to have a technician come to your home or office and change out your wheels for you

Sudden play & random tugging in steering wheel. Hear clicking from steering wheel & front left tire both while driving straight.
ANSWER : Hello, thank you for writing in. Checking the brakes was a great place to start. At this point the first thing we need to find out is if symptoms happen always, or only when driving over bumpy roads. If you feel it only when going over bumps, you want to check the suspension. If the suspension is not up to par on the vehicle, you will feel and fight those forces in the steering wheel. You can perform a bounce test, and do a visual inspection to see if the suspension shows any signs of leakage or damage. This would include the ball joints. If the suspension seems to be okay, you want to turn your attention to the rack and pinion. For more help with diagnostics and resolving the issue, contact our service department.
