TechIQ: Pothole Wheel Bearing Noise

Tech IQ: Pothole Wheel Bearing Noise (VIDEO)

When impact occurs the damage eventually causes turbulence. This video is sponsored by Auto Value and Bumper to Bumper.

How can a pothole strike in December cause a bearing noise in January? In this video, we cover how a pothole damages the races of a bearing and how the driving increase the size of the damaged area.

When the damage happens the damage causes turbulence. The turbulence in the grease increases temperatures of the grease. Burned or oxidized lubricant may leave a dark coating on bearing surfaces. If a bearing overheats, the hot lubricant breaks down and can cause scoring and even etching of the bearing surfaces.

Also, water and other corrosive elements can create this condition, which leads to spalling in a few months.

Clutch-based limited slip differentials are common on many automotive applications like trucks and SUVs, but they present a unique problem. These differentials often use different clutch configurations, either cone or flat type, made with various materials and frictional requirements. When both wheels have ample traction, the clutch plates bind together tightly, sending consistent power to each wheel. When one wheel slips, additional power is sent to the other wheel based on the frictional properties of the clutch packs. This is where the gear lubricants frictional properties play an important role in functionality and performance.
