|The first few things a fleet maintenance team usually consider when implementing lubrication maintenance are the engine and the transmission because of how important they are to the truck’s functionality. While those are important, it’s also critical to examine lubrication of other components such as the chassis – which has a direct impact on truck reliability and uptime. If not properly maintained, trucks can have issues with steering or suspension.
In the front suspension, lubrication is needed for the front wheel bearings, ball joints, control arm bushings and tie-rod ends. The lubricant can be applied with a grease gun or by hand, with regreasing occurring typically twice a year.
Rear suspension axles often contain bushings that require periodic greasing. Rear wheel bearings are usually connected by an axle to the rear differential and do not require external grease.
