Replacing a rear wheel bearing can be a tricky proposition. If the old bearing is still in good shape, you may be able to simply press it out and press the new one in. However, if the bearing is damaged or otherwise worn out, you`ll need to press it out using a bearing press.
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.
You should replace your hub assembly and wheel bearings. Here`s how to replace wheel bearings. Even if only one side is bad, it makes sense to replace them in pairs. The “good” side is likely to cause problems in a relatively short time.
For context, the tolerable end-play for truck wheel bearings is the same: 0.001 to 0.005 inches, also expressed as 1 to 5 mil or 0.025 to 0.127 mm. In other words, it`s perfectly acceptable to adjust wheel bearings so that they are just a little bit loose, but not too loose.
You can lower your wheel bearing replacement cost by changing them yourself. You should be able to do this in your own garage. However, it will require some specialized tools.
Over-tightening can damage the lug nuts, wheels and hubs – and worse, result in a wheel-off situation.
It`s important to do it right the first time because an improperly installed wheel hub assembly leads to a variety of problems, including: Unnecessary stress and strain on the hub, CV joint, axle, and transmission. The wheel seizing up.
Responsible for attaching the wheel to the car, a wheel hub assembly is a pre-assembled unit that features precision bearings, seals and sensors.
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.
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.
Once you notice any sign indicating a bad wheel bearing, avoid exceeding 500 miles with that issue. A failing wheel bearing will increase your difficulty in driving. But with a high-quality wheel bearing, you can drive for another 1000 miles as per the estimate.
Loose ball bearings cause the wheel to become wobbly and make your bike feel unstable. Luckily, ball bearings can be tightened with some quick work.
If your wheel bearing fails, it can cause the wheel to stop while you are driving or possibly even to fall off. At the very least, before a wheel falls off, a failed wheel bearing can/will cause significant damage to your vehicle, so it`s very important to keep an eye on these and keep them maintained.
Wheel bearings 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 failure prematurely.
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.
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.
Rear hubs are considered to be safer because of stronger dropouts in the rear. Rear hub motors may be a bit hard to install and complicated when it`s compared to a front hub. You will need a freewheel for Rear hubs and freewheels are mostly limited to 6 or 7 speed.
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.
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 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.
For rear hubs, the common number is 9 balls of 1/4-inch diameter per side. For front hubs, the common number is 10 balls of 3/16-inch diameter per side.
The average wheel bearing will have a lifespan of 136,000 to 160,000 km (85,000 to 100,000 miles). Certain factors such as the quality of the wheel bearings, installation, and car modifications can affect its actual lifespan.
There are many contaminants that can cause problems with a bearing. Dirt, sand, and water are the most common ones that you run into, but chemicals and corrosives can also damage bearings.

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.

ANSWER : When I replace a hub, I don’t necessarily remove the CV joints. I do, however, remove the nut that is holding the CV joint onto the hub. You will need to remove the brakes and rotor, the upper and lower ball joints (replace if damaged), remove the tie rod end (replace if damaged), and the sway arm from the hub.
