Do these need to be pressed onto the axle or spindle?

These are complete bolt-on assemblies—no pressing required. They mount directly to your vehicle's factory attachment points with standard fasteners.

What tools do I need to install them?

Socket set, jack, jack stands, and a torque wrench. Work on a level surface with the vehicle properly supported. Refer to your service manual for torque specs.

Are wheel speed sensors included for ABS systems?

Mounting provisions for sensors are factory-standard; confirm whether your vehicle uses ABS sensors and source separately if needed.
