Turbocharger Damage: Most Common Causes And How To …

 · Impeller damage caused by contact with the turbo housing. On the right, we can see a broken shaft shank, which is usually caused by operating the turbocharger for a prolonged time without enough oil. The shaft material can thus burn out and break due to the friction between the shaft and the bearings.

Impact Damage On Wheel Hubs

 · Impact Damage On Wheel Hubs. When a driver hits a pothole or curb hard enough, extreme forces are put onto the balls or rollers and races of the bearing. This can result in the formation of a very small mark on the surfaces. The driver might go 1,000 miles or more before these components start making noise. Advertisement.

Calcaneus (Heel Bone) Fractures

Calcaneus (Heel Bone) Fractures. A fracture of the calcaneus, or heel bone, can be a painful and disabling injury. This type of fracture commonly occurs during a high-energy event—such as a car crash or a fall from a ladder—when the heel is crushed under the weight of the body. When this occurs, the heel can widen, shorten, and become deformed.

What Causes Bearing Failures? | Know Your Parts

Once the bearing has worn through this layer, rapid and catastrophic wear occurs to the softer metal below. This type of fatigue failure is called "spalling." This kind of damage causes the metal to come off in flakes. If a bearing overheats, the hot lubricant breaks down and can cause scoring and even etching of the bearing surfaces.
