Making sure the unit is securely in place prevents damage to other components of the vehicle. Check (RESOURCE) for torque specifications. Keeping a torque wrench within reach during replacement jobs helps you keep customers’ vehicles on the road.

Why go through a supplier for parts when buying online is so easy?

Even if the part looks perfect in a photo online, what you get is not always what you see. Online auction sites have been known to misrepresent the quality of parts, and you may experience roadblocks when trying to return problem products. Whether buying online or off, using a trusted supplier with a stellar reputation helps protect your professional reputation.

Why is an Original Equipment (OE) replacement part my best choice?

Using a hub assembly from manufacturer with an OE heritage will always be your best choice. An OE manufacturer has the design & engineering expertise to ensure you have the correct fitting & functioning part for each vehicle’s needs. This is very important for every passenger vehicle owner, since the initial replacement cost in replacing a hub assembly is expensive. It is vital to understand that the short-term cost associated with using a premium OE replacement part for this critical safety component far outweighs the risk of using a low-cost option that you will have to replace more often, or can the increase the chance of catastrophic failure.
