FAQs

Q1: Do I need to replace both hubs if only one is failing?

A: It is not mandatory, but highly recommended. Since both hubs endure similar mileage and driving conditions, replacing them as a pair ensures balanced handling and saves you from paying for a second labor fee later.

Q2: Is it safe to use an impact wrench to tighten the axle nut?

A: No. Impact wrenches can easily over-torque the nut, which crushes the internal bearing rollers and causes premature failure. Always use a calibrated torque wrench to the exact factory specification.

Q3: Why is my steering wheel shaking after the hub replacement?

A: This usually indicates that the hub was not seated perfectly flat against the knuckle, or the wheel studs were not torqued in the correct star pattern. It could also mean the brake rotor needs to be resurfaced.
