Temporary fix forbad wheel bearing

Electrical damage. The passage of electrical current from one ring to the other through the ball, even at low currents, can lead to electrically induced bearing damage over time. The high current of an arcing event causes flaking of the surface material and tempering or melting and re-hardening of the raceway, which forms craters in the raceway and damage to the rolling elements. Even if arcing leaves the bearing intact, the high temperatures wreck the lubricant, which damages the bearing.

Driving with bad wheel bearing

Next, press the wheel side-to-side from the 3 and 9 o’clock position. If it is wobbly or there is excessive play, it will need to be replaced. If it feels secure, try this test from the 12 and 6 o’clock positions. If there is excessive play, it will need to be replaced.

Incorrect installation. There are lots of ways to f-up bearing fit, including mounting shaft bearings by applying pressure to the outer race, mounting bearings into a housing by applying pressure to the inner ring, loose fits, tight fits, housings that are out-of-round and bearing seats with a poor finish.

Overloading. Whenever a bearing operates beyond rated capacity for temperature, speed or load, overloading occurs. This could be due to production demands, operator error or lower manufacturing standards. Don’t take too much of a load off, however. Bearings need a minimum load to function properly, particularly cylindrical roller bearings which are designed for heavier loads. The exception is preloaded bearings.

If you’ve completed a brake job and are unsure about replacing the wheel hub and bearing assembly yourself, check out our wheel hub installation how-to videos to see if you can do it yourself and replace the defective wheel hub as soon as possible.

How to tell whichwheel bearing is badwhiledriving

If you’re thinking there’s a lot that can go wrong with motor bearings, you’d be right. Fortunately, there’s a single action you can take to extend the life of your bearings and, as a result, your electric motors: put a good preventive maintenance program in place.

Overheating. Bearings have different clearances to allow for thermal expansion during operation, so selecting the correct bearing for the application is important.

Misalignment. This one can be sneaky, since a motor and load that’s aligned when powered off may be misaligned when normal operation increases the temperature. Watch out for soft foot. (No, soft foot isn’t some weird old timey dance step your grandparents did. It’s improper contact between the machine casing and the base plate, and it’s a major cause of alignment issues.)

How long can you drive ona bad wheel bearing

Motor bearings are responsible for 51% of all motor failures. (The U.S. Department of Energy puts the number even higher, at 67%.) Find out why bearings are important, what causes bearing failure and get a checklist so you know what to do about it.

Improper lubrication. According to an article in Reliable Plant, 80% of bearing failures are the result of lubrication failure. That’s a lot of responsibility for a little bit of grease. Lube your bearings properly with the right type of lubricant and keep an eye on motor temperature, as high temps degrade lubricant.

You can confirm the wheel bearing is bad by raising the vehicle at the wheel. Put the transmission in neutral and chock the wheels. Turn the wheel and if there is resistance and the wheel does not turn freely or smoothly, the wheel bearing will need to be replaced. Since many models have the wheel bearing and wheel hub as a complete assembly, both will likely have to be replaced.

Bearing failure is rarely simple. What looks like the cause on first examination may not be what started it all, which is why a root cause analysis is an important way to prevent problems from occurring again. (Our essential guide to motor failure offers some quick tips on doing a root cause analysis.)

Bearings are critical to the efficient functioning and longevity of an electric motor. Rolling element bearings support and situate the rotor, ensure a small and consistent air gap between the rotor and stator, and transfer load from the shaft to the frame. Without bearings, the motor loses efficiency and power and has increased friction and vibration. Not surprisingly, when bearings fail, there is increased drag, more heat and reduced efficiency.

Because driving on a bad bearing is a safety hazard, it’s important to replace your bearings with trusted quality. We have many direct-fit and long-lasting hubs made of quality materials with long warranties to guarantee a quality replacement.

Driving on a bad wheel bearing could lead to a dangerous situation. Not only can it make driving unpleasant with loose or vibrating steering or grinding and whirring sounds, but it can put your safety at risk by simply not allowing the wheel to turn as smooth while driving, and in some cases can cause the wheel to come off entirely.

Contamination. Watch out for moisture (either from humid environments or temperature swings that cause condensation), poor quality lubricant, acid, dust and dirt. They all cause corrosion.

Luckily, the culprit leaves evidence behind. Each of the events that leads to bearing failure has a unique damage pattern, and a trained investigator can use clues such as denting, cracking, metal fragments, residues, grooves, marks and wear paths and hints such as noise, colour, shape, orientation, temperature and vibration to identify the perpetrator.

Annoying sounds, sloppy steering, and a potential loss of a wheel does not make for a good or safe combination while driving. A wheel bearing is not a part that should be ignored if it is failing.
