Don’t throw your Mack Truck spindles away! We replace those too, saving you time and money.
Loose kingpins can cause steering difficulties and excess tire wear that can increase your operating cost. Too often, the traditional rebuilt kingpin lasts only half as long. When a technician rebuilds your kingpin, he should also examine the knuckle eyes for wear. Simply replacing the kingpin set overlooks worn knuckle eyes that give the kingpin just enough play to erode the holes faster than normal. A trained Axle Doctor® specialist can in-line bore and sleeve knuckle holes for a precise fit and give your kingpin set a full life.
