Read on to learn the most common bad wheel bearing symptoms, based on my experience (50 years in the industry) and that of Joe Simes, a National Institute for Automotive Service Excellence (ASE) certified and Toyota master technician. But first, a little background.

Friction from a failing wheel bearing produces heat. After driving, without touching the tires or wheels, carefully walk around your vehicle and use a non-touch thermometer to measure if one is hotter than the others.

Beyond its small form factor, this lens also features a notable optical design that incorporates two aspherical elements and three Extra-low dispersion elements to control distortion and aberrations for improved clarity and sharpness. The front has a 46mm thread for screw-in filters – offering creative and exposure control for landscape photography.

On many vehicles, the ABS sensor is built into the wheel bearing, or it’s externally mounted adjacent to the spinning part of the bearing where the sensor measures vehicle speed. Damaged from a wobbly wheel bearing, the sensor will send erratic readings to the vehicle’s computer, illuminating the ABS light.

The average cost to replace a sealed wheel hub bearing is $350 per wheel. However, depending on the make and model, shop labor rate, the cost of the bearing itself and any additional damage, the total could exceed $1,000.

Unlike unbalanced tires, shaking caused by a bad wheel bearing should be obvious from the side of the car where the bearing is failing.

NOTE: Whether you DIY or your mechanic replaces the bearing, always install a new axle hub nut. Most hub nuts are prevailing torque fasteners, used on critical components (like securing axle shafts to hub bearings) where a loose nut could lead to disastrous consequences.

The Laowa 7.5mm f/2 MFT is the widest f/2 rectilinear lens ever designed for Micro Four Thirds cameras. Despite the impressive specifications, Laowa has successfully reduced the weight to less than 200 g (7 oz.) and length to only 55 mm (2.16 in.) long. The optical performance and distortion control are outstanding.

According to Simes, a failing wheel bearing will likely produce a soft, faint vibration that’s felt before it’s heard. There may also be a vague rhythmic humming or droning sound that increases over time and with speed.

This feather-weight lens opens up a new opportunity for photographers to shoot wider coverage with gimbals and drones. Thanks to its compact size, the lens perfectly pairs up with compact Micro Four Thirds cameras as an ideal every-day lens.

This lens is currently the widest rectilinear lens available for Micro Four Thirds cameras. It gives a field of view equivalent to a 15 mm lens on 35 mm sensors. This allows MFT users to enjoy an impressive 110° ultra wide angle of view for a broad range of shooting. The wide angle of view and ultra-fast aperture are extremely valuable for astro-photography. This lens is super compact and lightweight for casual on-the-go use. A ultra-light version is also available for aerial photography usage.

On modern front- and four-wheel drive cars, wheel bearings are a set of permanently sealed, precisely machined steel ball or straight roller bearings. The balls, or rollers, are encased in a “cage” that supports the bearings, allowing them to rotate freely.

Due to its compact, lightweight design, the Laowa 7.5mm f/2 MFT is excellent for Vlog and lifestyle videography, like weddings, travel, music videos, etc. This small lens is a perfect match with your gimbal or stabilizer, letting you shoot videos with ease and efficiency. No need to carry big, bulky and heavy equipment ever again! More video samples can be found on the “Testimonials” page.

Simply stated, wheel bearings allow cars and trucks to run smoother and more efficiently by reducing friction and supporting vehicle weight. When they start to fail, you can usually tell.

This lens loves working in dark and difficult lighting conditions. The extreme 110° angle of view and ultra-fast f/2 aperture allow photographers to create impressive astro-photography shots with ease. It also gives photographers a fast wide angle option for low-light, architectural and landscape photography.

The cage and rollers are held together inside a hardened metal ring called a “race.” The seal keeps grease in and damaging water and debris out. Wheel bearings are installed inside, and secured to, the suspension, either by press fit, bolts or a snap-ring. Once mounted, the wheel bearing rides on the axle shaft, allowing the tire/wheel to spin effortlessly.

You can service or replace tapered wheel bearings yourself. Never reuse any wheel bearing that’s loose, worn, noisy or shows any signs of wear.

Depending on the vehicle, you can save hundreds in labor replacing wheel bearings yourself. Most auto parts stores will lend you the specialty tools and equipment needed to replace a wheel bearing.

But sealed wheel bearings are non-serviceable and should never be repaired, only replaced. Even if a pro suggests repairing a bearing, don’t let them. Trying to reuse a damaged wheel bearing can result in an accident and severe injury.

You’ll hear clicking, cracking, grinding, snapping, or whining noises coming from your wheels or tires. They’ll increase when accelerating or turning.

Absolutely not. It’s crucial to get bad wheel bearings diagnosed and replaced ASAP. If not, you could lose a wheel or get in an accident.

The Standard & Lightweight versions of the Laowa 7.5mm f/2 are now available. They share the same optical design but differ in weight. Both have metal construction, but, we carefully designed and replaced some of the materials to lower the weight from 200 g (Standard) to 150 g (Lightweight). The Lightweight version is specially designed to work with drones.

A bad wheel bearing can cause a tire/wheel to move or glide unevenly or sluggishly. It can also cause your brakes to drag, pulling your vehicle to one side when you try to stop.

The Laowa 7.5mm f/2 MFT is compatible with Panasonic, Olympus & Blackmagic cameras with Micro Four Thirds lens mounts. The lightweight version is specially designed for drones & gimbal usage.

Venus Optics was formed by a group of passionate industry experts and photographers who wish to create Unique, Practical & Affordable wide-angle and macro lenses.

Please note: the 7.5mm f/2 MFT (standard version) has no electronic connections with the drones/gimbals and therefore, there is no electronic control of the aperture or focus. If you hope the metadata can be saved in EXIF, you are suggested to pick the automatic aperture version.
