Diagnosing and Replacing a Wheel Bearing on Your 2013-2018 Lexus ES300h
That humming or roaring noise from your wheels isn't normal; here's what Lexus ES300h owners need to know about fixing it.
- The primary symptom of failure is a humming or roaring noise that changes with wheel speed, not engine speed.
- The front requires a difficult press-in bearing replacement, while the rear uses a much simpler bolt-on hub assembly.
- For reliability, choose OEM-quality aftermarket brands like NSK, NTN, SKF, or Timken over cheaper economy options.
- A wheel alignment is necessary after replacement to prevent uneven tire wear.
Is Your Lexus ES300h Making a Humming Noise?
The most common sign of a failing wheel bearing in the 2013-2018 Lexus ES300h is a noise coming from one of the corners of the car. This noise is often described as a hum, roar, or growl. It will start faint and get progressively louder over weeks or months. A key indicator is that the noise changes with vehicle speed, not engine RPM. 🎬 Watch: How to diagnose and confirm a bad wheel bearing You may also notice the pitch or volume changes when you steer left or right; for example, a failing right-front bearing often gets louder when turning left, which puts more load on it.
Front vs. Rear: A Critical Difference
When shopping for a wheel bearing for your ES300h, it is crucial to know whether you are working on the front or the rear of the car. The parts and the replacement procedure are very different.
- Front Wheel Bearing: The front uses a press-in bearing. This means the bearing itself is a standalone part that must be pressed out of the steering knuckle and a new one pressed in using a hydraulic shop press. This is a difficult job that requires special tools and is not recommended for most DIY mechanics.
- Rear Wheel Bearing: The rear uses a complete bolt-on wheel hub assembly. This part contains the bearing, hub, and ABS sensor ring in one unit. It simply bolts onto the rear knuckle, making the replacement much easier and DIY-friendly for someone with moderate mechanical experience. 🎬 See this walkthrough for replacing the rear hub assembly
Common Ordering Mistake
Do not buy a complete front hub assembly thinking it's a simple bolt-on part. For the front, you need only the bearing itself (Part #510063 is a common aftermarket number), which must be professionally pressed. 🎬 Watch: How a professional mechanic presses in a front bearing The rear is sold as a complete assembly.
Choosing the Right Aftermarket Wheel Bearing
Lexus does not manufacture its own bearings; they use high-quality parts from specialized suppliers. You can get the same quality, or very close to it, from the right aftermarket brands. For a critical part like this, quality matters more than price.
Tier 1: OEM Quality Brands
These brands are often the original suppliers to Toyota/Lexus and are widely trusted by professional mechanics. For maximum longevity and a quiet ride, choosing one of these is your best bet.
- NSK & NTN: These Japanese brands are very likely the original equipment manufacturers for your ES300h. Choosing them is the closest you can get to buying a genuine Lexus part.
- SKF & Timken: These are top-tier global bearing manufacturers with a long-standing reputation for quality and durability.
- FAG: A German brand (part of the Schaeffler group) known for precision engineering and high-quality bearings.
Tier 2: Quality Mid-Range Brands
These brands offer a good balance of quality and value. They are a solid choice if premium brands are out of budget.
- Beck Arnley: Known for sourcing parts that match the form, fit, and function of the original foreign nameplate parts, sometimes even re-boxing the OEM part.
- Mevotech & National: Generally considered reliable aftermarket brands. National is often associated with Timken.
Tier 3: Economy Brands
This category includes many private-label or lesser-known brands like WJB and TrueDrive. While the low price is tempting, forum discussions and mechanic experience often show these bearings have a much shorter lifespan and may become noisy again in as little as six months. They are not recommended if you plan to keep your car.
Pro Tip for Front Bearing Replacement
One owner on a Lexus forum reported repeated failures of new front bearings. The problem was eventually traced to a slightly warped or rusted steering knuckle that was damaging the new bearings upon installation. If you are replacing a front bearing, ensure your mechanic thoroughly cleans and inspects the inside of the knuckle for damage before pressing the new bearing in.
Cost to Replace a 2013-2018 Lexus ES300h Wheel Bearing
Costs vary based on your location, the chosen part quality, and whether you're replacing a front or rear bearing. The labor for a front press-in bearing is significantly higher than for a rear bolt-on hub.
| Part/Service | Estimated Cost (Per Wheel) |
|---|---|
| Aftermarket Part | $30 - $96 |
| OEM Part | $220 - $300 |
| Shop Labor (Front - Press-in) | $240 - $360 |
| Shop Labor (Rear - Bolt-on) | $150 - $220 |
| Total (Front) | $270 - $456 |
| Total (Rear) | $180 - $316 |
Frequently Asked Questions (FAQ)
Do I need to replace wheel bearings in pairs?
It is not strictly necessary, but it is often recommended. Wheel bearings on the same axle experience the same wear and tear. If one has failed, the other may not be far behind. Replacing them in pairs can save you a future trip to the shop.
Will I need a wheel alignment after replacement?
Yes, a four-wheel alignment is highly recommended after replacing either a front or rear wheel bearing. The process requires disconnecting suspension components, which will alter your alignment angles. Driving without a proper alignment will cause premature tire wear.
What happens if I don't replace a bad wheel bearing?
Continuing to drive on a bad wheel bearing is dangerous. The noise and vibration will worsen, and the bearing can eventually fail completely. This can cause the wheel to lock up or even separate from the vehicle, leading to a total loss of control.
Could the ABS light be related to the wheel bearing?
Yes. The wheel speed sensor, which the ABS and VSC systems rely on, reads a magnetic ring on the wheel bearing assembly. When the bearing becomes loose or wobbly, it can disrupt this signal or damage the sensor, triggering the warning lights on your dashboard.
