The Timken 203AB is a deep groove ball bearing used in power steering pump shaft applications. It is built for smooth rotation, controlled noise, and stable performance under proper lubrication, making it a direct-fit service part for select Toyota steering systems.

Key Features

  • Deep groove bearing design for power steering pump shaft support
  • Engineered for low noise and reduced vibration in rotating assemblies

Detailed Description

Timken 203AB is a steering bearing replacement for Toyota applications that require a deep groove ball bearing in the power steering pump shaft. It fits 1980-1988 Toyota Pickup, 1980-1987 Toyota Land Cruiser, 1984-1989 Toyota Van, and 1985-1989 Toyota 4Runner. This part cross-references National 203 for the same application.

Timken’s bearing construction focuses on consistent fit, smooth operation, and dimensional accuracy. The 203AB part number is a practical choice when replacing a worn steering pump shaft bearing on Toyota Pickup, Toyota Land Cruiser, Toyota Van, or Toyota 4Runner models from the listed years.

Common Issues This Part Can Address

  • Noise from a worn power steering pump shaft bearing

  • Reduced smoothness in pump rotation
  • Service replacement for a bearing that no longer maintains proper tolerance

Installation Notes and Tips

Verify bearing dimensions and pump housing condition before installation. Clean the shaft and bearing bore thoroughly, and use proper lubrication during assembly. Press the bearing in evenly to avoid damage to the race or rolling elements. Confirm fitment by year, make, and model before ordering the Timken 203AB.
