Detailed Description

PWR 42-1941 is a hydraulic steering rack built for direct replacement in the 2003-2009 Toyota 4Runner and 2003-2009 Lexus GX470. It features a 1246 mm end-to-end length, two mounting holes, and a steering input shaft with 36 splines and a 19 mm diameter. The unit includes inner tie rods and a gasket or seal, while mounting hardware, mounting brackets, outer tie rods, and brackets are not included.

This part cross-references Atlantic Automotive Engineering 3473N and Maval 9378M for the same application. PWR 42-1941 is also listed against OE-style interchange numbers 262624 and 361696.

What It Helps Address

• Excessive steering play or looseness
• Hydraulic steering fluid leaks at the rack
• Noise or roughness during steering input
• Uneven or inconsistent steering response
• Wear-related failure in the original rack and pinion assembly

Installation Notes and Tips

Verify spline count, shaft diameter, and line fitting sizes before installation. This hydraulic rack uses female inlet and outlet fittings, so confirm line routing and connection style on the vehicle before assembly. Because mounting hardware is not included, reuse or source the required fasteners as needed. Professional alignment is recommended after installation on any Toyota 4Runner or Lexus GX470 steering repair.

Quality Assurance

PWR states that its pumps, racks, and gears are tested for leaks, pressure, noise, and function before release. The manufacturer also identifies this unit as USA engineering approved for direct-fit service.
