Wheel Bearing
The dual-row ball bearing assembly in the hub is the primary load-bearing component. Environmental contamination from mud or water often breaches the integrated seals, causing the internal lubrication to emulsify and fail. This leads to high-friction metal-on-metal contact between the steel balls and the races, creating the reported grinding sound.

Front CV Axle Assembly
If the protective neoprene boot is punctured or torn, the molybdenum disulfide grease is evacuated by centrifugal force. Without lubrication, the internal balls and cage assembly within the CV joint experience rapid thermal expansion and abrasive wear. This manifests as a grinding or binding noise, especially during steering articulation or high-torque acceleration.

Sintered Brake Pad Set
Off-road environments frequently introduce silicate debris into the caliper housing, which can become embedded in the friction material. If the pads are worn to the wear indicator or the steel backing plate, the interaction with the rotor surface produces a consistent grinding. This is often exacerbated on Polaris units when the caliper slide pins fail to retract fully due to corrosion.
