Wheel Hubs and Bearings for GMC Sierra 2500HD

Much like the engine, the hubs for the GMC Sierra 2500HD make up an important structural part of the vehicle. A hub assembly allows the wheelbase on all GMC cars and trucks to be mounted to the proper torque specifications for an ideal driving experience. As both wheel hubs and bearings have some moving parts, its important to know how they function, what upkeep you need to do, and when and how to replace them.

The hub assembly, or WHA, and its bearings act as a mounting unit for the wheelbase of your GMC Sierra vehicle. Although it does require some basic upkeep and occasional replacement, as all moving parts do, it is still a relatively simple mechanical metal design. In addition to being a home for the bearings, the hub also acts to support the lug nuts that keep everything attached. The bearings are what help the Sierra to turn smoothly, and this is why it is important to make sure your bearings are in good condition. If your hubs and bearings are worn out, you may hear grinding indicative of damage to the overall structure of the vehicle.

In addition to its primary use, a WHA has several parts that you should also keep an eye on and check occasionally for maintenance or replacement. Knowing what these parts are and how they function can better prepare you when they wear out.

• Hub seal: This is designed to keep your Sierras bearings lubricated properly and protect them from dirt, dust, and other debris that may interfere with their functionality. These seals can become worn or cracked over time, and its a good idea to have extra seals on hand in case you need to replace one quickly for the sake of the bearings.
• Steering knuckle spindle: This part, such as a GM OEM front suspension knuckle, provides the support that the inner and outer GMC Sierra 2500HD truck bearings need to rotate properly.
• Axle spindle nuts: These hold the lugs in place on the Sierra 2500HD assembly itself.

Because of the plethora of moving parts in this diesel or gas-powered vehicle, it will sometimes be necessary to replace certain aspects of your GMC wheel hub assemblies. However, there are also some preventative maintenance techniques you can use. Part of preventative maintenance involves looking for signs that your GMC pickup truck may have faulty or worn out assembly parts. Some of these signs include the following:

• A humming or rumbling noise when driving your Sierra 2500HD could indicate a problem with your bearings. This noise will occur even when driving in a straight line and become stronger if you are turning the vehicle.
• You may need to replace your suspension knuckle components if you experience vibrations at a constant rate of speed.
• If you experience delayed engagement, automatic transmission slips, or rough shifts, you may have a transmission problem. Its important to address these issues quickly, as they can affect the wheels of your GMC pickup truck, including the hubs and bearings.
