Will I need new bolts or fasteners to install these?

The assembly itself bolts directly to factory mounting points. Whether you reuse your existing fasteners or swap them depends on their condition—inspect them during removal and replace anything that looks corroded or stripped.

Do these require any prep work before installation?

Clean the mounting surface on the axle or knuckle before sliding the assembly on. No painting or special surface prep needed—the bearing is sealed and ready to go.

Can I use these on both front and rear, or are they specific to one axle?

Verify your axle location and brake configuration when ordering—front and rear assemblies are different units. Check your vehicle's service manual or contact our team with your specific setup if you're unsure which you need.
