Review INFINITI Sedan Driveshaft Piece Automatic 37300ac70b Oem fits G35 AWD 2004–2006

The **Infiniti G35 (2004-2006) AWD Driveshaft (Part Number: 37300-AC70B, 23BH1F0)** is a precision-engineered component designed to deliver seamless power transfer between the transmission and the rear axle in Infiniti s iconic all-wheel-drive (AWD) models. This driveshaft is a critical element of the G35 s AWD system, ensuring optimal handling, stability, and performance across a variety of driving conditions, from spirited highway cruising to dynamic cornering. Crafted from high-grade steel and featuring a robust, balanced construction, it is engineered to withstand the demands of daily driving while maintaining durability over the long term. The driveshaft incorporates a **constant velocity (CV) joint at the transmission end**, allowing for smooth angular movement and reducing wear during sharp turns, while the **spline shaft** ensures precise alignment and torque transfer to the rear differential. Its **black powder-coated finish** not only enhances its aesthetic appeal but also provides added protection against corrosion, making it well-suited for both urban and off-road environments. Whether you're restoring a classic G35 to factory specifications or upgrading an existing driveshaft for improved reliability, this part is a direct OEM replacement, guaranteeing an exact fit with the original equipment manufacturer s standards. Its compatibility with the **3.5L V6 engine** and **6-speed automatic transmission** (A356/A357) ensures seamless integration, while its **universal application** across the 2004-2006 model years makes it a versatile solution for enthusiasts and mechanics alike. Built to meet Infiniti s rigorous quality benchmarks, this driveshaft exemplifies the brand s commitment to performance, precision, and longevity, making it an essential component for maintaining the G35 s legendary driving dynamics.

### **Pros and Cons of Buying a 2004-2006 Infiniti G35 (37300-AC70B) with AWD, Automatic Transmission**

#### **Pros**

1. **Strong Performance and Handling**

The G35 is a well-regarded sports sedan with a naturally aspirated 3.5L V6 engine producing around **306 horsepower** (in the base model) and **330 hp** in the SE-R variant. The AWD system improves traction in adverse conditions while maintaining sharp driving dynamics. The manual transmission (if available) enhances engagement, but the automatic is smooth and reliable.

2. **Reliability and Longevity**

The G35 is known for its robust engineering, particularly the **3.5L V6 (VQ35DE)** and **5-speed automatic transmission (Jatco JF506)**. With proper maintenance, these components can easily last **200,000 miles**. The AWD system (Nissan s **NAS system**) is also durable if serviced regularly.

3. **Comfortable and Refined Ride**

The G35 offers a **well-balanced ride** agile enough for spirited driving but comfortable for daily use. The suspension tuning strikes a good middle ground between sportiness and smoothness, making it suitable for both city and highway driving.

4. **Strong Resale Value**

Compared to many competitors (e.g., BMW 330i, Audi A4), the G35 holds its value well, especially in AWD and automatic trim. This makes it a practical choice if you plan to keep it long-term.

5. **AWD Advantage**

The **all-wheel-drive system** provides better stability in snow, rain, or off-road conditions compared to FWD models. This is particularly useful if you live in a region with harsh winters or enjoy light off-roading.

6. **Good Interior Quality and Features**

The cabin is **well-built** with **high-quality materials**, especially in higher trims. Standard features include **power windows, locks, cruise control, and a decent sound system**. The **SE-R** variant adds sport seats, a limited-slip differential, and a more aggressive stance.

7. **Affordable Maintenance Costs**

Compared to German luxury brands, the G35 has **lower repair and maintenance costs**. Parts are widely available, and labor costs are typically reasonable. The **oil change interval (5,000 7,500 miles)** is more frequent than some European cars, but this is standard for Japanese engines.

8. **Aftermarket Support**

The G35 has a **strong aftermarket community**, with widespread availability of **tuning parts, suspension upgrades, and performance modifications**. This allows owners to enhance power, handling, or aesthetics if desired.

9. **Fuel Efficiency (Compared to AWD Sports Sedans)**

- **Manual (FWD):** 20 MPG city / 28 MPG highway

- **Automatic (FWD):** 18 MPG city / 26 MPG highway

- **AWD (Automatic):** 17 MPG city / 24 MPG highway

This is better than many European rivals but worse than a Toyota Camry.

10. **Timeless Design**

The G35 s **aerodynamic, aggressive styling** remains appealing decades later. The **LED taillights (on later models)** and **sleek bodywork** give it a modern look even today.

---

#### **Cons**

1. **Higher Maintenance Costs Than Japanese Economy Cars**

While cheaper than German brands, the G35 still requires **more frequent oil changes** (every **5,000 7,500 miles**) than a Toyota or Honda. Neglecting this can lead to **engine wear**. The **timing chain** (not a belt) is also a potential long-term concern if not serviced properly.

2. **AWD System Can Be Overkill for Most Drivers**

The **NAS AWD system** adds weight and complexity. If you **rarely drive in snow or off-road**, the extra cost and maintenance of AWD may not be justified. The **rear differential** in AWD models can also be a weak point if not properly lubricated.

3. **Manual Transmission Not Available in All Markets (Especially AWD)**

Many **2004-2006 G35 AWD models** came only with the **5-speed automatic**. If you prefer a manual, you may need to look for an **FWD version**, which lacks the AWD advantage.

4. **Rear Seat Space is Tight**

The G35 is a **two-door coupe**, meaning **rear legroom is limited**. If you frequently carry passengers or cargo, this could be uncomfortable.

5. **Susceptibility to Rust (Especially in Snowy Regions)**

The **wheel wells, rocker panels, and undercarriage** can rust if the car was exposed to salt or poor maintenance. Always **check for rust** before purchasing, especially in older models.

6. **Head Gasket Issues (Rare but Possible)**

While uncommon, **head gasket failures** have been reported in some **VQ35DE engines**, particularly if the car was overheating or maintenance was neglected. This is more likely in **high-mileage examples**, so a **pre-purchase inspection is crucial**.

7. **Limited Boot Space**

The **trunk is small** (around **10 12 cubic feet**), making it difficult to carry large items like suitcases or groceries. This is a common trade-off for a sports sedan.

8. **Some Electrical Gremlins**

Like many Japanese cars of this era, the G35 can have **occasional electrical issues**, such as **intermittent power window malfunctions, sensor problems, or infotainment glitches**. These are usually fixable but can be annoying.

9. **Depreciation Over Time**

While the G35 holds value better than most, it still **loses equity** over time. If you plan to sell it in **5 7 years**, the remaining value may not fully offset the purchase price.

10. **Potential Transmission Issues in Higher Mileage Examples**

The **5-speed automatic (JF506)** is generally reliable, but **higher-mileage units (150,000 miles)** may develop **slippage, rough shifting, or solenoid failures**. A **transmission fluid flush** can help, but a **full rebuild may be needed** in severe cases.

---

### **Conclusion**

The **2004-2006 Infiniti G35 (37300-AC70B) AWD automatic** is an **excellent choice** for drivers who want a **balanced blend of performance, reliability, and comfort** without the high cost of a German luxury car. It excels in **handling, power delivery, and long-term durability**, making it a **great daily driver and weekend sports car**.

- **Prioritize rear seat space or cargo capacity** (due to the coupe design).

- **Live in a region with minimal winter driving needs** (AWD adds cost without much benefit).

- **Prefer a manual transmission** (most AWD models were automatic).

- **Want ultra-low maintenance** (oil changes are frequent, and some components require attention).

If you **inspect the car thoroughly** (checking for rust, transmission health, and engine condition) and **budget for regular maintenance**, the G35 is a **fantastic purchase** that will provide **years of enjoyable driving**.

---

### **Recommendation**

You want a **reliable, fun-to-drive AWD sports sedan** with **strong performance and good resale value**.

You **drive in snowy or wet conditions** and value AWD.

You **plan to maintain it properly** (oil changes, fluid checks, rust prevention).

You **don t mind a small trunk** and are okay with **tight rear seats**.

You **enjoy tuning and modifying** (strong aftermarket support).

You **need a family-friendly car** with **more cargo space**.

You **rarely drive in adverse weather** (AWD may not be worth the extra cost).

You **prefer a manual transmission** (most AWD models are automatic).

You **find significant rust, transmission issues, or engine problems** in the inspection.

The **2004-2006 Infiniti G35 AWD automatic** is a **smart buy for enthusiasts** who want a **Japanese-built sports sedan with AWD capability, strong performance, and long-term reliability**. With **proper care**, it can easily last **200,000 miles** and remain a **joy to drive**. Just **verify its condition** before purchasing to avoid costly surprises.
