What to Look for in a Quality Wheel-Hub Assembly

What to Look for in a Quality Wheel-Hub Assembly

Make sure you’re recommending a unit that’s engineered strong enough to do the job right, easy to install and built for a long service life.

When you’re recommending a replacement hub assembly, what are some of the characteristics of a quality unit that can stand up to the wheel forces, heat and loads that put these critical wheel-end components to the test? 

The hub spindle is a great place to start. Increasing the thickness of the flange on the spindle adds strength to protect it from warping under impact and safeguards it against vibration due to runout.

How about the seals? Hub-bearing seals keep lubricating grease in and contaminants out, and they play a critical role in the service life of the hub assembly. The inboard seals on a quality hub assembly will feature multiple sealing lips that redirect contaminants out, and they might introduce a metal shield over the top of the seal. And premium hubs will have robust outboard multi-lipped seals and better shielding.

Recommending Emission-Control Parts

When a check engine light comes on, customers rely on you for the right part to keep it off.

When a check engine light comes on, your customers want the right part to ensure that light goes off and stays off. They turn to you for expert advice, so be sure you have the correct parts they need when they need them. There are many different components that make up the EVAP system. They can read like alphabet soup sometimes, so it's important that you know how to understand a customer's complaints. Equally important, you need to recommend the right replacement to eliminate their problems. Modern evaporative emission control systems are selective with how they vent vapors back into the engine. The PCM will select the right engine temperature and throttle position to purge the system. They're also very selective when system checks are performed. A computer is constantly monitoring the results of the command sent to the valves. With the help of sensors mounted in the tank and the EVAP canister standards, complete EVAP program includes products that match OE design performance to keep vehicles running clean.
