49001-JA000 Power Steering Rack for 49001Ja000 Nissan Altima Teana 2.5 J32

Core Product Description

The 49001-JA000 Power Steering Rack is a hydraulic steering gear for Nissan vehicles including the Altima and Teana. 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. According to parts data, the 49001-JA000 is cross-referenced with multiple OE numbers including 49001-JN00A,49001-JB50A,49001-JN01A. The rack is confirmed for Nissan models including the Altima (2007-2013, L32/J32 chassis) and Teana II (2008-2013, J32) .

The rack is a hydraulic type and is designed as a direct replacement for the original equipment. This is a LHD (left-hand drive) steering rack, not for RHD vehicles. The installation process is complex and must be completed by a qualified mechanic.

DIY Diagnosis GuideHow 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

💡 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.

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.

Direct Replacement – Precision-engineered to match the original rack specifications. Direct bolt-on replacement – no modifications required. This part supersedes 49001-JA00B.

Proven Compatibility – This rack is confirmed compatible with Nissan Teana J32 and Nissan Altima LHD models .

Essential for Steering System Service – When steering components are worn, replacing the steering rack ensures complete and reliable steering system function. Power steering fluid must be filled and the system bled of air after installation.

Installation Tips & Common Mistakes

The Mistake When Replacing a Power Steering Rack:

❌ Wrong: Failing to flush the system or using incorrect fluid, and not performing a wheel alignment.

✅ Correct:

1. Use the correct fluid – Use Nissan PSF or Dexron III ATF as specified.

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

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

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

5. Bleed the system properly – Turn lock-to-lock with the engine off first, then with the engine running until bubbles clear.

⚠️ 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 Altima/Teana J32 Steering System:

The Nissan Altima (2007-2013) and Teana II J32 (2008-2013) use a hydraulic power-assisted rack-and-pinion steering system. The 49001-JA000 steering rack is the LHD version for these vehicles.

Key Information:

• Part numbers: 49001-JA000, with cross-references to 49001-JA00B, 49001-JA010, 49001-JN00A

• Drive type: FWD (front-wheel drive)

• Steering type: Hydraulic power-assisted rack and pinion

• Platform: Nissan D platform (shared between Altima and Teana)

Common Failure Modes :

• Seal leakage – Red/brown fluid weeping from the rack, lines, or inside boots

• 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

• Boot failure – Torn boots allow dirt entry and accelerate rack wear

Service Tips :

• Use Nissan PSF or Dexron III ATF as specified

• Flush fluid every 60,000–100,000 km

• Replace tie rods and boots when doing the rack

• A proper wheel alignment is essential after rack replacement

Note:  Confirm with your specific seller.

After Replacement Still Having Issues?

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

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

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

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

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

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

6. Is the power steering fluid the correct type? – Use Nissan PSF or Dexron III ATF

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.

 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.

Steering Column U-Joint – The u-joint connects the steering column to the rack. Worn u-joints can cause steering play and vibration. Inspect while the rack is removed.
