Do I need to replace both sides at the same time?

Yes—this kit supplies both sides as a matched pair. Installing both ensures even braking response and suspension geometry. If one bearing is worn enough to need replacement, the opposite side is typically at a similar lifespan.

What tools do I need to install these?

You'll need a socket set, breaker bar, wheel removal tools, and a hub puller or press. Consult your factory service manual for torque specs and any specialized tool requirements specific to your suspension setup.

Are there any hardware or fasteners included?

The kit includes the hub bearing assemblies only. Any bolts, clips, or seals required for installation should be sourced separately or reused from your OEM components—verify against your service manual before starting.
