2 What Type Of Hub Assembly Should I Choose?

Based On Material

When buying new hub assemblies you can select either aluminium or steel wheel hubs based on the construction material. Deciding what is best for you, depends on your needs.

1. Aluminum Vs Steel Hub Assemblies

Aluminium hub assemblies are lighter and thus reduce your vehicle’s overall weight and increase fuel efficiency. Due to the design and material used, these hubs are costly as compared to steel hubs. Steel hub assemblies are more dependable as they require low maintenance. These hubs provide greater strength, and wear resistance and are less expensive. However, they weigh more than aluminium hubs. If you want to keep your costs down and weight isn’t your concern you must go for the steel hub or else you can purchase aluminium hubs.

Based On Construction Type

1. Pre-Set / Pre-Adjusted 

In pre-set hub assemblies all parts of the wheel hub unit like the bearings, seals, sensors and sensor wire are pre-assembled. Therefore, it decreases installation time, reduces the possibility of installation errors and keeps your expenses low as you don’t have to invest in installation tools. Even though preset hubs reduce installation errors, this type of hub will still require maintenance and replacement over time. 

2. Conventional Hub Assemblies

Conventional hubs require assembly and do not come manufactured and assembled with bearings and seals which leaves room for alignment errors during installation compromising the vehicle’s safety. Although purchasing these separately can save you on costs but unless you have adequate skills, the right equipment and knowledge these assemblies are not recommended.

Based On Type Of Bearing Used

1. Ball Bearings

They are the most common type of wheel bearing and also the most versatile. Ball bearings can absorb both radial and thrust loads. Radial load is the amount of weight put on a wheel, while thrust load is the cornering pressure. They also offer low friction owing to their minimal contact area with the rolling elements. These types of bearings are suitable for vehicles like sports cars with high engine speeds.

2. Tapered Roller Bearings

Tapered roller bearings are most often used in standard car and truck wheels or vehicles that are subjected to higher side loading. That’s because of their ability to absorb high radial forces due to their large contact area of the rolling elements in the races. However, tapered roller bearings aren’t suitable for high engine speeds.

3 What Factors Should I Consider Before Buying A Hub Assembly?

A. Compatibility

For the wheel bearing to fit properly and ensure your vehicle and all passengers remain safe, you should check the make and model of the vehicle as well as the number of lug nuts in the wheel. Lug nuts hold the wheel and tire assembly on the vehicle and are fastened onto special studs. These studs are pressed through the back of the hub. It is important to take into consideration the number of lug nuts and vehicles’  load capability as this can impact the bearing you choose.

B. Choosing The Right Material 

Aluminum hub assemblies are lighter, corrosion-resistant, and have better thermal conductivity. The higher thermal conductivity value of aluminum ensures to protect the bearing from damage if it becomes heated due to friction. The only drawback to aluminum is the higher cost. Whereas the steel hub assemblies are heavier but require low maintenance, provide greater strength, and are less expensive. If you want to keep your costs down and looking for a balance of all features it is recommended to select steel hubs.

C. OE Vs Aftermarket

Replacement OE components offer the same advantages as factory-equipped parts. But this means you will not be receiving any additional benefits which can be found in aftermarket products. OE parts will also cost quite a bit more than their aftermarket counterparts. Aftermarket components are generally cheaper and provide many benefits over the standard hub assemblies. Aftermarket components match the fit and performance of the OE parts and some even exceed that. Hence making them a bargain over OE counterparts.
