The Timken HA590486 Wheel Bearing and Hub Assembly is a complete unit designed to simplify installation and ensure the smooth operation of the wheel and axle. Here are the key components typically included in this assembly:
1. Wheel Bearing:- Pre-Installed Bearing: The wheel bearing itself is a crucial component, allowing the wheel to rotate smoothly with minimal friction. In this assembly, the bearing is pre-installed and sealed within the hub to protect it from dirt, debris, and moisture.
- Hub Flange: The hub flange is the part of the assembly that connects directly to the wheel and brake rotor. The wheel studs are part of this flange, and the wheel is bolted onto it.
- Wheel Studs: The assembly includes wheel studs, which are the threaded posts that the wheel lugs attach to. These studs are typically pre-installed on the hub flange.
- Integrated ABS Sensor: Some Timken hub assemblies, including the HA590486, come with an integrated ABS (Anti-lock Braking System) sensor. This sensor monitors wheel speed and sends signals to the vehicle's ABS control unit to help prevent wheel lock-up during braking.
- Sensor Wiring: The assembly may also include the wiring harness or connector for the ABS sensor, designed to plug directly into the vehicle’s existing ABS system.
- Bearing Seals: The assembly includes seals that protect the bearing from contamination and help retain the grease inside the bearing. These seals are essential for maintaining the bearing's longevity and performance.
- Mounting Flange: The backside of the hub assembly has a mounting flange that attaches to the vehicle's suspension knuckle or spindle. This flange is secured to the suspension with bolts (which are typically reused from the original assembly).
- Retaining Clip or Snap Ring: Some assemblies include retaining clips or snap rings that hold the bearing securely in place within the hub. These are essential for maintaining the structural integrity of the assembly.
The Timken HA590486 Wheel Bearing and Hub Assembly includes the wheel bearing, hub flange with pre-installed wheel studs, seals, and often an integrated ABS sensor with its corresponding wiring. The assembly is designed as a direct replacement for the original hub assembly, making installation straightforward and ensuring that all components are compatible and correctly aligned. This design helps simplify the repair process and ensures reliable performance of the vehicle's wheel and suspension system.
