Rein PSH0518 Power Steering Pressure Line Hose Assembly

OE-Quality Power Steering Hose Assembly

Rein PSH0518 is a direct-fit power steering pressure line hose assembly for the Toyota 4Runner. It is built as an OE-quality replacement for the high-pressure feed line and is engineered to match the factory routing, fittings, and pressure switch port configuration where required.

For 2010-2024 Toyota 4Runner applications, this hose assembly is designed to restore proper hydraulic steering performance while reducing installation time compared with rebuilding individual line sections.

Key Features

• Direct-fit replacement hose and line assembly
• SAE J188 compliant high-pressure rubber hose with internal noise absorber
• SAE J526 compliant heavy-duty tubing and end fittings with rust-resistant coating
• Pre-assembled coated hose crimp ends and brackets where required
• Protective jacket and heat sleeve included where required by OE design
• Pressure switch port included as specified by the original equipment layout
• Rein part number PSH0518 for application-specific steering repair

Detailed Description

Rein PSH0518 is a power steering pressure line hose assembly engineered for the Toyota 4Runner from 2010 through 2024. The assembly uses SAE J188 compliant rubber hose with an internal noise absorber, along with SAE J526 compliant steel tubing sections and corrosion-resistant end fittings. Rein also incorporates coated crimp ends, pre-assembled brackets where required, and OE-style sealing hardware and pressure switch port placement to match the factory configuration. This makes PSH0518 a practical choice when replacing a leaking, damaged, or noisy high-pressure steering line on a Toyota 4Runner.

This part cross-references 4441360110 for the same application.

Common Problems This Part Can Address

• Power steering fluid leaks from a cracked or corroded pressure line
• Steering noise caused by worn hose construction or internal line restriction
• Loss of steering assist from pressure loss in the hydraulic system
• Fitment issues when replacing a line with incorrect brackets or port locations
• Corrosion-related failure in the original high-pressure feed hose assembly

Installation Notes and Tips

Verify the vehicle’s factory line routing, pressure switch port location, and bracket layout before installation. Because this is an application-specific assembly, compare the original hose to Rein PSH0518 before removal to confirm the correct configuration for your Toyota 4Runner. After installation, inspect all connections for seepage and bleed the power steering system according to OE service procedures.

Quality Assurance

Rein tests each high-pressure feed hose assembly for tensile strength, burst pressure, low-temperature flexibility, impulse durability, and corrosion resistance. PSH0518 is backed by a 24-month, 24,000-mile warranty.
