Hi guys, it’s Mark Phillips. Wheel bearings. They make the world go ‘round. Most serviceable wheel bearings need maintenance every 25,000 to 30,000 miles, or during every brake service. But, the average life of a sealed wheel bearing and hub assembly is about 85,000 to 100,000 miles, without the opportunity for a technician to repack the bearings. As a result, your customer may only have one chance during a vehicle’s life to replace these parts. If you miss this opportunity, it may be gone forever.
