Spindle Maintenance
Do You Have a Problematic Spindle?
Wheel bearing maintenance is a crucial yet often overlooked aspect of commercial vehicle upkeep. Many truck owners are unaware of the importance of regular wheel bearing checks and lubrication changes. If neglected, this can lead to damaged spindles and dangerous situations as break pads can become compromised by leaking bearing lubricants and grease.
When inspecting your truck for signs of trouble, listen for unusual noises like whirring, clicking, or clunking, particularly while turning. Unusual vibrations can also be an indicator as well as visual signs like bearing grease leaking from the boot. A quick visual inspection of the inner side of the wheel’s rim will help identify any issues.
