Why do wheel bearings need grease?
Grease is used in these wheel bearings in order to lubricate them, and inhibit problems like overheating and corrosion that are caused as a result of continuous friction. Inadequate lubrication can also bring down the lifespan of a wheel bearing by a great extent as lack of lubrication subjects them to intense wear and tear. Heat produced as a result of continuous driving can also add to your woes by damaging the wheel bearings, and so does excessive load and misalignment. Other than all these problems, wheel bearings of a vehicle can go bad after a certain period even when you put in all the maintenance efforts, as they have a lifespan of certain years. In such circumstances, you are left with no option but to replace them to avoid further damage.

What Can Cause a Wheel bearing to Go Bad?
The truth is the thing that most often makes a wheel bearing go bad is simply driving . The constant revolutions coupled with the weight of your car will eventually wear out even the best bearings. If moisture gets into the bearing grease it can accelerate wear by decreasing the oil’s ability to lubricate and by allowing rust to form. Driving in the rain isn’t a big deal but driving through standing water may allow moisture into the bearing. Similarly adding load to the bearing can decrease its life and cause it to go bad early. Following the load rating of your vehicle can allow the bearings to live a long and easy life.
How to tell if a wheel bearing is bad?
Typically if the wheel bearing is going bad, you would hear a humming sound and the sound would intensify when making turns, depending on what side the wheel bearing going bad was.
How do You Know if You Have a Bad Wheel Bearing?
A wheel bearing will usually fail due to pitting or small damage on the surface of the rollers or the bearing race. Both the surface of the rollers and the race are precision machined to tight tolerances and highly polished to allow the rollers to pass easily over the race with the addition of bearing grease for lubrication and cooling. Over time the bearing will wear slightly, allowing microscopic pieces of metal into the grease. These microscopic pieces of metal, as well as any contamination that gets into the bearing, will wear away at the highly polished surfaces causing pitting and deformation. Since so much weight is riding on your wheel bearings, and so much load is put on them in corners, even the smallest amount of surface damage to your bearing can cause a lot of noise like a growling or humming or in some cases a grinding noise.
