49001-8H900 Power Steering Gear Rack FOR 490018H900 Nissan X-TRAIL T30

 Core Product Description

The 49001-8H900 Power Steering Rack is a hydraulic steering gear for the Nissan X-Trail T30 (2001-2007). Also known as a steering rack, steering gear, or rack and pinion assembly, this component converts the rotational motion of the steering wheel into linear motion to turn the front wheels, with hydraulic assistance to reduce steering effort .

This steering rack is specifically designed for left-hand drive (LHD) vehicles, as confirmed by multiple parts catalogues . The T30 X-Trail uses a hydraulic power-assisted rack-and-pinion steering system, as documented in the Nissan X-TRAIL T30 Factory Service Manual .

DIY Diagnosis Guide

How to Tell If Your Power Steering Rack Needs Replacement:

Look for these common signs :

1. Power steering fluid leaks – Red/brown fluid under the vehicle, weeping from the rack, lines, or inside the boots

2. Heavy steering – Steering feels unusually difficult, especially at low speeds

3. Notchy or uneven steering – Steering feels rough, notchy, or inconsistent when turning

4. Steering play / clunks – Excessive free play in the steering wheel, or clunks over bumps

5. Uneven tire wear – Tire wear patterns indicating steering alignment issues despite correct pressures and alignment

6. Poor self-centering – The steering wheel does not return to center well after turning

💡 Quick inspection: Check the power steering fluid level and condition. If fluid is dark, burnt, or contaminated, it needs a flush. With the vehicle off, turn the steering wheel slightly left and right—excessive play may indicate internal rack wear. Also inspect the rack boots for splits or moisture. For the T30 X-Trail, if the vehicle has high mileage and shows any of these signs, the steering rack may be worn .

Product Attributes

Why Choose This Steering Rack?

Restores Steering Precision – A worn rack creates play and vague steering feel. This new rack restores direct, precise steering control for confident driving .

Eliminates Power Steering Leaks – Worn seals cause fluid leaks that can damage other components and reduce steering assistance. This new rack comes with fresh seals for leak-free operation .

Prevents Uneven Tire Wear – A worn rack affects wheel alignment, causing rapid and uneven tire wear. Replacing it helps protect your tire investment .

Direct Replacement – Precision-engineered to match the original rack specifications. Direct bolt-on replacement – no modifications required. This assembly is a complete unit that replaces original part numbers 49001-8H900 and related variants.

Proven Compatibility – This rack is confirmed compatible with Nissan X-Trail T30 (2001-2007) LHD models . Multiple engine variants are supported including 2.0L petrol, 2.2L dCi diesel, and 2.5L petrol versions .

Essential for Steering System Service – When steering components are worn, replacing the steering rack ensures complete and reliable steering system function. The T30 X-Trail steering rack uses Nissan PSF or Dexron III ATF fluid and requires proper system bleeding after installation .

Package Contents

1 x Steering Rack and Pinion Assembly. Note: Inner tie rod ends may or may not be included depending on the supplier . Mounting bolts and power steering fluid are NOT included unless stated. Please confirm compatibility with your vehicle model, year, and drive type before purchasing.

DIY or Professional Installation?

This replacement is suitable for DIY if:

• You have advanced mechanical skills and the required tools (socket set, torque wrench, ball joint separator).

• You are comfortable working under the vehicle with steering and suspension components.

• The job takes approximately 4-6 hours.

We recommend professional installation if:

• You do not have the proper tools for steering rack removal and alignment.

• You are not comfortable with steering system repairs.

• You are not confident in your mechanical skills.

Note: Improper installation can lead to steering failure, safety issues, and warranty concerns. After installation, a professional wheel alignment is MANDATORY to ensure proper handling and prevent uneven tire wear . Power steering fluid must be filled and the system bled of air . The correct bleeding procedure is: with the front wheels off the ground, fill the reservoir, slowly turn lock-to-lock 10–20 times with the engine off, then start the engine and repeat until bubbles clear .

Common Misconceptions About Steering Racks

Myth 1: “If it’s not leaking fluid, the rack is fine.”
Fact: Steering racks can fail internally without any external leakage. Play, stiffness, or clunking can occur even without visible fluid loss .

Myth 2: “A wheel alignment will fix uneven tire wear caused by a worn rack.”
Fact: A worn rack with play cannot be aligned properly. Replacing the rack is required before alignment will be effective .

Myth 3: “All X-Trail T30 steering racks are interchangeable.”
Fact: T30 racks vary by drive type (LHD/RHD). This rack is specifically for LHD (Left-Hand Drive) vehicles . Confirm your vehicle’s drive type before ordering.

Myth 4: “Any power steering fluid will work in the T30.”
Fact: The T30 X-Trail requires Nissan PSF or an approved Dexron III ATF equivalent. Mixing fluid types or using incorrect fluid can damage seals and cause leaks .

Common Customer Concerns & Our Solutions

We understand that purchasing a steering rack can raise questions and concerns. Here is how we address the most common issues our customers face:

“How do I know if this rack fits my X-Trail?” – This rack fits Nissan X-Trail T30 models in LHD configuration . Check your vehicle’s steering wheel position – if it‘s on the left side, this is the correct rack. It fits multiple engine variants including 2.0L, 2.2L dCi, and 2.5L .

“What power steering fluid does my X-Trail use?” – The T30 X-Trail typically uses Nissan PSF or an approved Dexron III ATF equivalent. Always check the reservoir cap for the correct specification and avoid mixing fluid types .

“What if I do not get a wheel alignment after rack replacement?” – A wheel alignment is MANDATORY after rack replacement . Without it, the vehicle will pull, steering will be off-center, and the front tires will wear out quickly and unevenly.

After-Sales Service & Warranty

This product is covered by our quality assurance. If you have any questions or issues regarding fitment or quality, please contact us and we will respond within 24 hours.

 Related Product Recommendations 

When replacing the power steering rack on the Nissan X-Trail T30, it is often recommended to inspect and consider replacing the following related components at the same time .

Inner and Outer Tie Rod Ends – The tie rod ends connect the steering rack to the steering knuckles. If they are worn, steering precision will be affected. Replace as a set when replacing the rack to avoid double handling .

Steering Rack Boots – The boots protect the rack from dirt and moisture. If they are torn, they should be replaced to prevent contamination of the new rack .

Steering Rack Mount Bushings – The rack mounting bushes can perish and cause vagueness and vibration through the wheel. Replace if worn .

Power Steering Pump – The pump supplies hydraulic pressure to the rack. If the pump is failing, steering will be heavy even with a new rack. Inspect for noise and fluid flow .
