To determine if your 2011-Present Lexus GS might have a wheel bearing issue, we'll need some more information, such as the year of your vehicle and the specific symptoms you're experiencing. Assuming you're referring to a "tire bearing," it's likely that you mean the wheel bearing, which can be a common source of trouble in cars.
Typically, signs of a bad wheel bearing include an audible sound that becomes more pronounced as your vehicle's speed increases. This noise often resembles a low-pitched "wubwubwubwub" sound and can usually be heard from inside the car's cabin.
You can perform a basic check for a damaged wheel bearing by following these steps:
# Safely lift your vehicle using jack stands.
# With one hand on the top of the wheel and the other on the bottom, attempt to gently wiggle the wheel back and forth without spinning it.
# If you notice any play or excessive movement in the wheel during this test, there's a good chance that your wheel bearing may be damaged.
Keep in mind that a visual and hands-on inspection by a qualified mechanic is the most accurate way to diagnose a wheel bearing issue. If you'd like, you can also provide a video or audio recording of the sound you're hearing, and I'd be happy to listen and offer additional insight or confirmation of the issue.
