With few exceptions, these manufacturers set wheel end bearings to the 0.001” to 0.005” endplay range using older torque-based technology. As a result, the high variability of endplay settings can lead to poor wheel end performance built into many new vehicles.
Temper Axle’s Rode notes that this is changing fast, as a number of major players up and down the commercial vehicle OE supply chain are working to equip their wheel end production lines with preload adjustment technology to deliver the best performing wheel ends possible.
