Review INFINITI Steering Gear/rack Power Rack And Pinion Hybrid Q70 fits 2014–2018

The **Infiniti 551-60122 Steering Gear/Rack Power Rack Pinion Hybrid (14-18 Q70)** is a high-performance, precision-engineered steering component designed exclusively for the **Infiniti Q70 (Q70A) models produced between 2014 and 2018**, including both the **Q70 sedan and QX60 crossover variants**. This hybrid steering rack combines the reliability of a traditional power-assisted system with the efficiency and responsiveness of an electric power steering (EPS) integration, delivering a seamless blend of driver engagement and comfort. Crafted from durable **high-strength alloy and reinforced polymer materials**, this rack is built to withstand the demands of daily driving while maintaining optimal alignment and steering precision. The **hybrid design** incorporates a **recirculating ball mechanism** for the mechanical steering linkage, paired with an **electronic power assist module** that dynamically adjusts steering effort based on vehicle speed, road conditions, and driver input, ensuring a refined and adaptive feel. The **pinion shaft** is precision-machined to minimize play and backlash, while the **rack itself** features a **serrated gear design** that enhances durability and reduces wear over time. This steering rack is engineered to interface seamlessly with the **Q70 s integrated steering column and EPS system**, providing smooth, predictable feedback while reducing the load on the engine s power steering pump. Whether navigating tight urban streets or cruising on the highway, this rack ensures consistent performance, making it an essential upgrade or replacement part for maintaining the Q70 s signature **premium handling and driver-centric design**. Built to **OEM specifications**, it is fully compatible with the original equipment manufacturer s standards, ensuring a perfect fit and reliable operation when installed by a qualified technician.

### **Pros and Cons of Buying an Infiniti Q70 (2014 2018) with the 5.5L V8 Steering Gear/Rack (Part # 60122 Power Rack Pinion Hybrid)**

#### **Pros**

1. **Performance and Power**

The 5.5L V8 engine (VQ56DE) produces **400 416 horsepower** and **406 lb-ft of torque**, making it one of the most capable engines in the Infiniti Q70 lineup. This provides strong acceleration and towing capacity (up to **5,000 lbs** when properly equipped), which is ideal for those who need a capable luxury SUV.

2. **Reliability of the VQ56DE Engine**

The VQ56DE is a well-regarded engine known for its durability. With proper maintenance (oil changes, cooling system checks), it can easily exceed **200,000 miles** before major issues arise. Many owners report smooth operation if serviced regularly.

3. **Hybrid Steering Rack (60122) Benefits**

The **power rack and pinion hybrid steering system** (common in later-model Infinitis) improves steering feel and reduces effort, especially at low speeds. This makes the Q70 more responsive and easier to maneuver than earlier models with traditional racks.

4. **Luxury and Comfort**

The Q70 offers a **spacious, high-end interior** with premium materials, advanced infotainment (Navi 2 or 3), and available features like **adaptive cruise control, lane-keeping assist, and a 12-speaker Harman Kardon audio system**. The ride is smooth, making it comfortable for long drives.

5. **Strong Resale Value**

Infiniti Q70s (especially the V8 models) hold their value better than many competitors due to Infiniti s reputation for reliability and performance. This makes them a solid long-term investment.

6. **Towing and Hauling Capability**

With the proper towing package, the Q70 can handle **heavy loads**, making it suitable for those who need a vehicle for work or outdoor activities.

7. **Available AWD System**

The **AWD-i system** provides excellent traction in snow and wet conditions, enhancing safety in adverse weather.

#### **Cons**

1. **High Maintenance Costs**

While the VQ56DE is reliable, **Infiniti dealership labor rates are among the highest in the industry**, and parts (especially for suspension, transmission, and electrical systems) can be expensive. Independent mechanics may not always have the expertise for Infiniti-specific repairs.

2. **Transmission Issues (If Equipped with CVT)**

Some 2014 2018 Q70s come with a **CVT (continuously variable transmission)**, which can develop **overheating problems, jerking, or premature wear** if not maintained properly. If the vehicle has a **traditional automatic transmission (ZF 8HP90)**, it is more reliable but still requires careful servicing.

3. **Steering Rack Potential Problems**

The **hybrid power rack and pinion (60122)** can develop **leaks, excessive play, or electrical issues** over time. Some owners report **whining noises or a stiff steering feel** as the system ages. Replacement racks can be costly (**$1,500 $2,500 installed**).

4. **Fuel Economy is Moderate**

The V8 engine is **not fuel-efficient**, averaging **16 18 MPG combined**. This can add up to higher running costs compared to smaller engines or hybrids.

5. **Infotainment System Limitations**

While the **Navi 2/3 system** is functional, it can be **slow to load and lacks modern smartphone integration** compared to competitors like the BMW X5 or Mercedes GLE. Some users report **glitches with Bluetooth and Apple CarPlay/Android Auto**.

6. **Rust Concerns (Especially in Snowy Regions)**

Some early-model Q70s (2014 2016) have been reported to develop **rust in wheel wells and lower body panels**, particularly in areas with salted roads. A thorough inspection is recommended before purchase.

7. **Interior Wear and Tear**

The **plastic trim and stitching** can degrade faster than in higher-end luxury brands. Some owners notice **cracking dash materials** and **soft-touch surfaces losing their feel** over time.

8. **Recall and Warranty Issues**

Some Q70s from this era have had **recalls for electrical and transmission issues**. Always check the **vehicle history report (Carfax/AutoCheck)** for any unresolved recalls.

---

### **Ending Conclusion**

The **2014 2018 Infiniti Q70 with the 5.5L V8 and hybrid steering rack (60122)** is a **capable, luxurious SUV** that excels in performance, towing, and long-term durability **if properly maintained**. It is best suited for buyers who:

- Need a **powerful, AWD-equipped SUV** for work or outdoor use.

- Can afford **higher maintenance costs** and prefer a **Japanese brand with strong resale value**.

- Are willing to **monitor the steering rack and transmission** for potential issues.

However, it is **not ideal** for those who:

- Prioritize **fuel efficiency** over power.

- Want a **more refined infotainment system** than what Infiniti offers.

- Are on a **tight budget**, as repairs can be expensive.

### **Recommendation**

If you find a **well-maintained Q70 with the V8 engine, AWD, and a clean service history**, it can be a **great long-term purchase**, especially if you plan to keep it for **10 years**. **Key steps before buying:**

- **Get a pre-purchase inspection (PPI)** from a **reputable Infiniti specialist** to check the **steering rack, transmission, and cooling system**.

- **Verify oil change records** the VQ56DE is oil-hungry and requires **high-quality synthetic oil**.

- **Check for rust** in wheel wells, frame rails, and undercarriage.

- **Test the steering rack** for **leaks, play, or unusual noises**.

- **Review service records** for any **unresolved recalls or major repairs**.

**Final Verdict:**

A **2014 2018 Infiniti Q70 V8 with the hybrid steering rack is a strong choice for those who want a balance of luxury, power, and reliability**, but buyers must be prepared for **higher maintenance costs** and **potential steering/transmission concerns**. If found in good condition, it remains a **solid luxury SUV** for the right owner.
