Automobile bearings play a crucial role in vehicle movement alongside tires. Proper lubrication is necessary for their operation; without it, bearing speed and performance can be compromised. Like all mechanical parts, Automobile bearings have a finite lifespan. So, how long do Automobile bearings typically last?
Understanding Automobile bearings
Automobile bearings, or wheel hub bearings, connect the tires, brake discs, and steering knuckles. Their primary function is to bear the vehicle’s weight and provide precise guidance for wheel rotation. This dual role requires them to withstand both axial and radial loads. Given their importance to tire function and overall vehicle safety, regular maintenance and timely replacement of bearings are essential. Properly maintained, Automobile bearings typically last around 100,000 kilometers.
Symptoms of Bearing Failure
If a car’s wheel bearing fails, it often produces a humming or buzzing noise that increases with vehicle speed. To test this, accelerate to a certain speed and then coast in neutral. If the noise persists, it’s likely a bearing issue.
Tips for Proper Bearing Maintenance
1. Use Specialized Tools: When removing the wheel hub bearing, always use the appropriate tools. This is crucial to avoid damaging other components, especially the tire bolt threads. For disc brakes, remove the brake caliper before using tools to take off the lock ring or pin.
2. Clean Thoroughly: Use a suitable cleaner to remove old grease, then wipe the bearing and inner cavity with a clean cloth before applying new lubricant.
3. Inspect the Bearing and Bearing Housing: Check for cracks or looseness. If any damage is found, the bearing should be replaced immediately.
4. Check the Fit of the Bearing and Shaft: The standard clearance should not exceed 0.10mm. Measure the shaft in both vertical positions to ensure accuracy. If the clearance is beyond the allowable limit, replace the bearing to restore proper fit.
Regular Inspection and Replacement
Even if there are no apparent issues, regular inspections and maintenance are recommended, especially at certain mileage intervals, such as 50,000 or 100,000 kilometers. This should include cleaning, lubrication, and checking the fit of the bearings.
Don’t Neglect Maintenance
Bearings are crucial for safe driving. Regular maintenance not only extends their lifespan but also prevents potential driving hazards. Ignoring bearing upkeep can lead to premature failure and more severe driving risks.
