Hubs and Bearings
When securing the road wheel retaining bolts to the correct torque, the bolts can loosen during vehicle use. The reason identified for this problem is corrosion between the disc and hub mounting faces. This results in a clearance that reduces the wheel bolt torque even when the bolts are secured correctly.
Premature bearing failure will impact a fleet’s efficiency with serious performance, safety and budgetary implications. Proper wheel bearing adjustment is a key factor for optimal bearing life. To reduce premature bearing failure in heavy duty wheel-end applications, the ideal bearing end-play setting should be between 0.001” and 0.005”.
When it comes to replacing bearings and races, NTN has a couple of recommendations we make to installers to ensure that our products meet their maximum life expectancy. When replacing the bearing and race, NTN encourages installers to: 1) Replace both components as a set 2) Ensure both components come from the same manufacturer Replace…
What’s the Difference? Bearing components must have hardened rolling surfaces in order to provide long life. In general, there are two ways to harden steel to the required level: Through Hardening and Case Hardening. Through Hardening In order to harden steel, the iron mix must contain a certain amount of carbon. Carbon dissolves in molten…
If you are replacing a wheel bearing on a late-model vehicle, you will be dealing with a wheel speed sensor. In the past decade, wheel speed sensors have been moving to inside or on the wheel bearing or hub unit. At this location, the wheel speed sensors are more accurate and often more protected from the elements.
Operating efficiencies in your shop can mean the difference between generating a profit and breaking even, so efficient installation of wheel hub assemblies should be a priority. You can increase efficiency using some straightforward techniques that are applicable to all shops.
Proper wheel hub installation reduces vehicle maintenance costs and extends the useful life of wheel hub assemblies and their related parts. Whether it’s preventing comeback wheel bearing replacements or abnormal wear on tires, proper installation can save your customers money (and time) down the road.
Wheel hub assemblies can fail and require replacement for a number of reasons, making it important to troubleshoot problems if these warning signs occur. Below are some proven troubleshooting methods can lead you in the right direction.
