Lexus ES300 Wheel Bearing

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.

Rumbling wheels

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.

Loose wheels

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.

Smoking wheels

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.

  • Trouble-free Tips in Keeping a Lexus ES300 Wheel Bearing in Good Shape 27 February 2013

    Your Lexus ES300's wheel bearings allow the wheels to move more smoothly and to rotate more freely. Keeping these tiny parts in good shape plays a big role in keeping your wheels tightly secured to the auto. Over time, these wheel bearings may exhibit signs of damages, which may include rumbling noises, loose wheels, and even complete detachment of the wheels. These defects may be a result of driving at high speeds, or the wheel bearings may have simply exceeded their service life. If you have no idea on how to perform maintenance on a Lexus ES300 wheel bearing, then this is your lucky day. Here are some trouble-free tips in keeping the parts in good shape:


    Regularly check bearings for holes and defects.


    Preventing damages is always the best form of maintenance, so to address possible defects quickly, regularly check the bearings for signs of wear and tear. Replace the parts if you already find signs of holes or marks. Performing this early is a life-saver because when left unattended, these damaged wheel bearings may lead to even more serious defects that can endanger you and your passengers. Aside from holes and marks, you should also try checking the wheels for excessive play. This is done by jacking up the vehicle and attempting to lift the wheels up and down and back and forth. The wheels should be tight on the axle. If they are not, it may be time to replace them already.


    Replace dried grease at least once a year and maintain habitual greasing.


    Automotive experts advise that the grease on the wheel bearings are to be replaced at least once a year. But before replacing the grease, the bearings should be cleaned first with a solvent. Make sure you have a cloth or a set of newspapers beside you because the procedure can be messy. Afterwards, allow the parts to dry completely. Once done, lubricate the bearings with a wheel bearing grease. Be aware that the grease can stain your clothing, so wear the appropriate cleaning attire.


    Tighten wheel bearings.


    Aside from regular greasing, the wheel bearings also need to be tightened. Over time, these parts can get loose and may cause excessive wheel play. Additionally, these parts can also get too tight, which may cause the premature wear of the bearings. Because of this, it is crucial that you regularly check the tightness of the tiny parts and adjust them accordingly.
