A failure of a front pressure-reducing bearing on a vehicle may have direct implications for maneuverability and safety of the vehicle.

Symptoms of a failed front pressure-reducing bearing:

Abnormal sound: A broken ball causes clattering sounds during turning.

Jamming: Track rusting makes the steering wheel more difficult to be straightened.

Grease leakage: There is lubricating grease thrown out of the bearing due to sealing failure.

Possible reasons for failures of a front pressure-reducing bearing:

Sealing failure: The dust cover is damaged, and consequently silt and water enter the bearing, contaminating the grease and accelerating wear.

Insufficient lubrication: The original lubricating grease has dried up, causing dry friction of metal and damage to the ball or track.

Material issues: Ordinary steel bearings used on low-end models may easily experience rust and fatigue-induced cracking.

Driving habits: Passing over speed bumps rapidly and frequently or fully locking the steering wheel can result in excessive impact loads.

Impact of related components: The additional pressure generated due to oil leakage of a shock absorbers or a weak spring can be transmitted to the bearing.

Service life of a front pressure-reducing bearing:

Ordinary family cars: 60,000~100,000 kilometers of mileage.

SUVs/off-road vehicles: 40,000~80,000 kilometers of mileage. The service life of front pressure-reducing bearings used on these vehicles are 30% shorter than those on ordinary cars due to heavier loads and rougher road conditions.

Performance cars/aggressive driving: 30,000~50,000 kilometers of mileage. High-frequency steering and impact can accelerate wear.
