Understanding the distinctions between steel and aluminum hubs is crucial when changing heavy-duty wheel bearings. So let’s graph the variations. You’ll see that dealing with steel hubs is less delicate than working with aluminum since steel is a more forgiving material. Additionally, it is frequently simpler to remove the race with a bearing remover without running the ʀɪsᴋ of damaging the hub or scratching its surface. Typically, the drive and trailer axles have steel hubs.

Then there are aluminum hubs, which are usually only present on steer axles. OEMs choose them because of their reduced weight than steel, which gives fleets the chance to increase fuel efficiency. Aluminum, on the other hand, is a less forgiving, softer material that is more readily scratched or ᴅᴀᴍᴀɢᴇd when bearings are taken out or put in. It is recommended to weld a bead around the interior of the bearing race, which shrinks the race and makes it easier to move, in order to remove bearings from an aluminum hub. This requires the use of additional tools, involves more steps, and takes more time.

Here are a few more pointers for installing wheel bearings on aluminum hubs: A broken aluminum hub can prevent the race from seating properly during the installation of bearings, leading to misalignment. Bearings that are out of alignment experience an uneven load distribution, which shortens their lifespan and results in early failure. Wheel bearing installation may benefit from heating the metal hub.

The installation will be made simpler by freezing the rice to cool it. Last but not least, it’s crucial to remember that because the bearing and the aluminum hub are made of different materials, fretting ᴅᴀᴍᴀɢᴇ, which can happen as the race rotates or creeps inside the hub, is more prevalent.
