49001-3XT0A Power Steering Rack for 490013XT0A Nissan Urvan NV350 E26

Product Function Description

The power steering rack and pinion assembly is a critical component of your Nissan Urvan‘s steering system. This hydraulic rack-and-pinion unit converts the rotational movement of the steering wheel into linear motion, turning the front wheels to control the vehicle’s direction. For the Nissan Urvan NV350 E26 (short wheelbase version), a properly functioning steering rack is essential for precise steering response, stable handling, and safe vehicle control in both passenger and commercial applications . This LHD (Left-Hand Drive) assembly is designed to factory specifications, ensuring proper fit and reliable steering performance . The part number 49001-3XT0A is confirmed for the short wheelbase version, while 49001-3XT0B is for the long wheelbase version .

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. Possible causes: low hydraulic oil or oil pump failure

3. Abnormal noise – Whining, groaning, or clunking when turning. Possible causes: dirty hydraulic oil, air bubbles, or line leaks

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

5. Slow steering return – Steering wheel returns to center slowly after turning. Possible causes: stuck control valve or damaged steering gear

💡 Quick inspection: Check the power steering fluid level. If it's low, there may be a leak in the rack. 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.

 Installation Guidelines

Tools typically required:

• Socket wrench set (metric)

• Torque wrench

• Ball joint separator

• Tie rod end separator

• Flare nut wrench (for power steering lines)

• Safety gloves and eye protection

General installation reference (always follow vehicle-specific service manual):

Important:

• The installation process of a steering rack is complex and must be completed by a qualified mechanic .

• This is a structural and safety-critical component. Proper torque values and installation procedures are essential.

• A professional wheel alignment is required after installation .

• Use the correct power steering fluid as specified in the vehicle manual .

• If you are unsure about any step, consult a qualified mechanic.

Installation Tips & Common Mistakes

The Mistake When Replacing a Power Steering Rack:

❌ Wrong: Ordering the wrong length rack (short vs long wheelbase) or failing to flush the system.

✅ Correct:

1. Verify the correct length – 49001-3XT0A is for short wheelbase; 49001-3XT0B is for long wheelbase .

2. Use the correct fluid – Use Nissan-approved PSF or equivalent fluid as specified on the reservoir cap.

3. Flush the system thoroughly – For optimal performance, flush the system when replacing the rack .

4. Inspect and replace tie rods and boots – While the rack is out, inspect and replace if worn.

5. Perform a wheel alignment – Any rack or tie rod work changes toe settings, so a proper alignment is required .

⚠️ Remember: The installation process of a steering rack is complex and must be completed by a qualified mechanic . A loose steering u-joint can cause a loss of steering control. Always torque the u-joint bolt to specification.

Industry Knowledge

Nissan Urvan NV350 E26 Steering System:

The Nissan Urvan NV350 E26 is a commercial van produced from approximately 2013 onward. It uses a hydraulic power-assisted rack-and-pinion steering system. The 49001-3XT0A steering rack is the LHD version for the short wheelbase / narrow body variant .

Key Information :

• Part numbers: 49001-3XT0A (short wheelbase / narrow body), 49001-3XT0B (long wheelbase / wide body)

• Drive type: Rear-wheel drive (RWD) / commercial van

• Steering type: Hydraulic power-assisted rack and pinion

• Production years: 2013-

• Body variants: Short wheelbase / Narrow body

Common Failure Modes :

• Seal leakage – Red/brown fluid weeping from the rack, lines, or inside boots. Check for hydraulic oil leaks.

• Internal wear – Rack and pinion teeth can wear, causing steering play and clunks over bumps.

• Tie rod end wear – Inner or outer tie rod ends can wear, affecting steering precision.

• Control valve issues – Stuck control valve can cause slow steering return .

Service Tips :

• Use Nissan-approved PSF or equivalent fluid

• Check hydraulic oil every 10,000 km and ensure it is clean

• Check oil pipe joints every 20,000 km to prevent leakage

• Replace tie rods and boots when doing the rack

• A proper wheel alignment is essential after rack replacement

After Replacement Still Having Issues?

Replaced the steering rack but still having issues? Check these :

1. Was the correct rack installed? – 49001-3XT0A is for short wheelbase; 49001-3XT0B is for long wheelbase

2. Is the power steering system properly bled? – Air in the system can cause noise and heavy steering

3. Is the power steering pump working correctly? – A failing pump can cause heavy steering

4. Are the tie rod ends properly torqued? – Loose tie rod ends can cause steering play

5. Is the steering column u-joint properly connected? – A loose u-joint can cause steering play

6. Has the wheel alignment been performed? – Alignment is mandatory after rack replacement

7. Is the power steering fluid the correct type? – Use Nissan-approved PSF or equivalent

8. Is the hydraulic oil dirty or contaminated? – Dirty oil can cause abnormal noise

9. Are there air bubbles in the system? – Air bubbles can cause abnormal noise and should be purged

Quality Assurance & Service Commitment

Quality Assurance:
Every component is manufactured under controlled production processes to ensure consistent dimensional accuracy and material integrity. Each unit undergoes the following quality checks before packaging:

• Dimensional inspection – critical mounting points and rack dimensions are verified against design specifications

• Hydraulic seal test – sealing integrity is confirmed

• Rack movement test – smooth operation is confirmed

• Surface finish inspection – corrosion protection and surface quality are visually verified

Packaging Protection:
Each power steering rack is individually sealed in protective packaging to prevent contamination and physical damage during storage and transit. The packaging includes a clear part number label for easy identification.

Service Commitment:

Related Product Recommendations 

When replacing the power steering rack, it is often recommended to inspect and consider replacing the following related components at the same time.

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.

Inner Tie Rod Ends – The inner tie rod ends are attached directly to the rack. They can wear and cause steering play. While the rack is out, inspect and replace if needed .

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.

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.
