Do CW Bearing hub assemblies meet OE standards?

Yes, CW Bearing hub assemblies are designed to meet the CW Bearing Quality Standard, which aligns with OE standards. CW Bearing conducts OE tests to ensure each hub meets or exceeds these quality benchmarks.

Does CW Bearing test their hub assemblies?

Yes, CW Bearing performs seven different tests to validate the design and performance of their hub assemblies, ensuring that each one delivers reliable quality.

Why are hub assemblies more commonly used in vehicles today?

Hub assemblies are increasingly popular because they are unitized, maintenance-free, and non-serviceable. Pre-set, pre-greased, and pre-sealed, they simplify installation and eliminate the need for ongoing maintenance.

Are all aftermarket hub assemblies the same?

No, aftermarket hub assemblies differ in quality. Some, like those from CW Bearing, meet or exceed original equipment specifications, while others may only fulfill basic dimensional requirements.

Can an impact wrench be used to install a hub assembly?

It’s best to avoid using an impact wrench. Instead, use a certified, calibrated torque wrench to prevent damage to the axle nut, threads, or other components.

Is it necessary to torque both the axle nut and the lug nut?

Yes, proper torquing of both the axle nut and lug nut according to manufacturer specifications is crucial for correct installation and to prevent potential equipment failure or injury.

Can bearings or seals be replaced in a hub assembly?

No, most hub assemblies feature non-replaceable, unitized bearings or flanges that are integral to the hub and bearing housing, making them non-replaceable.

Do hub assemblies include wheel studs?

Most hub assemblies come with wheel studs, though some do not. It is generally not recommended to reuse old studs with a new hub assembly.

Do wheel hub assemblies need to be greased?

No, unitized hub assemblies are pre-greased with the optimal amount of grease to ensure longevity and performance, so no additional greasing is necessary.
