• Power steering fluid leaks from a worn or cracked pressure line
• Loss of steering assist caused by pressure line failure
• Noise or erratic steering response related to hydraulic pressure loss
• Corrosion damage on the original steel tubing
• Fitment issues when replacing a damaged Toyota Land Cruiser pressure hose

Installation Notes and Tips

Verify the end fitting size and type before installation: this hose uses 16 mm male inverted flare connections at both ends. Confirm routing, clearance, and connection points against the original line on the 1988-1989 Toyota Land Cruiser before tightening the fittings. Inspect surrounding steering components, seals, and fluid condition so the replacement hose can be installed into a clean hydraulic system.
