Symptoms of a Faulty Lexus ES300 Wheel Bearing
Your Lexus ES300's wheel bearings may be not as prominent as other larger car parts, but they serve a crucial function for your auto's safety. Without these fully functional wheel bearings, you will find yourself in danger, especially when driving at high speeds. So, it is important for you to keep them lubricated and tightened as your car ages. But, even if they are properly maintained, there will come a time that they will wear, and you will have no choice but to replace them. If you think you have a wheel bearing problem, then better perform some troubleshooting. Here are a few symptoms of a defective Lexus ES300 wheel bearing.
The easiest to way to detect a faulty wheel bearing is by listening for a rumbling sound. Simply drive your auto and observe for unusual noises coming from the wheels. This low, rumbling sound should be more prominent as you turn the vehicle. In fact, you might even feel a change in the steering wheel or the auto's body. In other instances, a scraping sound may be heard. If you find it difficult to listen for this low rumbling sound, then another way to detect wheel noise is by simulating a panic stop. Simply hit the brakes quickly and observe for a louder bearing noise. A louder noise indicates a defective front wheel bearing while a quieter one tells a faulty rear wheel bearing.
Defective wheel bearings can cause the wheels to get loose. So, to troubleshoot, simply prepare the jack and lift your vehicle. Make sure you secure with jack stands as a safety measure. Once done, hold one of the wheels and attempt to lift it up and down. The wheel should be tight on the axle because working wheel bearings should make it difficult for you to move the wheel. If not, then you might have to find a wheel bearing replacement. Failing to notice loose wheels is very dangerous because they might get disconnected when you are driving.
If you find smoke coming from your wheels, then simply stop the vehicle. This indicates that the bearings are already bad because the grease inside the hubs is burnt due to metal-to-metal friction. When this happens, you should not drive the car and simply find a replacement right away.
