Toyota 4Runner & FJ Cruiser Billet Aluminium Power Steering Reservoir 2010 - 2024 (Replaces 44360-60321)

Replace your fragile factory plastic power steering reservoir with this premium billet aluminium upgrade, precision CNC-machined for superior heat resistance, structural durability, and long-term reliability. Factory plastic reservoirs are notorious for aging, discoloring, and becoming difficult to read after years of high-temperature engine bay exposure — and when they crack, the resulting fluid leaks can cause power steering failure with serious safety implications. This billet aluminium replacement solves the durability problem permanently while introducing a built-in anti-bubble baffle structure that reduces foam formation during steering input, eliminating the fluctuating power assistance and abnormal noise issues common to standard reservoirs. Unlike most metal aftermarket reservoirs that use fully sealed construction, this design integrates a reinforced PC sheet visual fluid level window — letting you check fluid level at a glance without removing the cap, making routine maintenance significantly faster and easier.

Features:

• Sturdy and durable construction – replaces fragile factory plastic with billet aluminium for superior resistance to heat aging, weathering, and impact damage
• CNC machined precision – ensures high dimensional accuracy for a perfect fit to factory mounting points and hose connections
• High-quality anodized finish – rust-proof and anti-corrosion treatment maintains a premium appearance over long-term engine bay exposure
• Anti-bubble baffle design – built-in internal baffle structure effectively reduces oil bubble formation during steering input, improving power steering stability and eliminating noise issues
• Visual fluid level window – reinforced PC sheet window provides clear, long-lasting fluid level visibility without removing the cap, while resisting aging and discoloration over time
• Direct OE replacement design – installs into factory mounting locations using existing hose connections for a clean, OEM-grade installation

Contents:

• 1x Billet Aluminium Power Steering Reservoir (with Visual Fluid Level Window)

Benefits:

• Billet aluminium construction permanently eliminates the cracking, leaking, and brittleness issues associated with aged factory plastic reservoirs – particularly critical on high-mileage 4Runners and FJ Cruisers exposed to years of engine bay heat cycling
• Anodized finish provides long-term corrosion resistance against engine bay conditions, road salt, and moisture exposure that would degrade plastic reservoirs over time
• Internal anti-bubble baffle structure reduces foaming and aeration in the power steering fluid, delivering more consistent steering assist and eliminating the whining noise that develops as plastic reservoirs age
• Visual fluid level window enables quick at-a-glance fluid checks without opening the reservoir cap – a significant maintenance convenience advantage over fully sealed metal aftermarket alternatives
• Reinforced PC window material resists UV aging, heat discoloration, and chemical exposure from power steering fluid for long-lasting clarity
• Significant interior engine bay aesthetic upgrade – replaces a discolored plastic reservoir with a premium machined aluminium component that elevates the overall engine bay appearance

Installation Notes:

• Direct OE replacement – installs into factory power steering reservoir mounting points using existing factory hose connections
• Confirm your factory power steering reservoir part number is 44360-60321 before ordering to ensure compatibility
• Drain factory power steering fluid before reservoir removal to prevent spillage – have a catch container ready
• Use only Toyota-specified power steering fluid (or equivalent) when refilling the new reservoir – do not mix fluid types
• Bleed the power steering system after installation to remove trapped air – turn the steering wheel lock-to-lock several times with the engine running, checking and topping off fluid level as air purges from the system
• Inspect all hose connections and clamps during installation – replace any aged or hardened hoses to ensure long-term leak-free operation
• Professional installation recommended if you are unfamiliar with power steering system service procedures
• If unsure about compatibility with your specific 4Runner or FJ Cruiser variant, contact our team with your year, model, and factory reservoir part number before ordering

Warranty:

• 12-month standard warranty from date of purchase
• Contact our support team for assistance with any issues
