Review BMW Hydraulic Power Steering Gear Rack And Pinion fits 750LI E65 E66 2002–2008

The **BMW 750Li (E65/E66) Hydraulic Power Steering Gear Rack and Pinion Assembly (Part Number: 6777259, Production Years: 2002 2008)** is a critical component of the vehicle s steering system, engineered to deliver the precise, responsive, and effortless handling that defines BMW s luxury sedan lineup. This high-performance steering rack and pinion assembly is designed specifically for the E65 and E66 chassis generations of the 750Li, which includes both the **750Li (L7) and 760Li (L7)** models, ensuring seamless integration with the vehicle s advanced suspension and chassis dynamics. Crafted from durable, high-grade materials, including reinforced steel and precision-machined aluminum components, this steering gear is built to withstand the demands of daily driving as well as spirited performance use, offering long-term reliability and minimal wear over extended mileage.

At the heart of this assembly is a **hydraulic power steering system**, which enhances steering effort with fluid-assisted force, reducing fatigue during long drives and providing a smooth, linear response to driver input. The rack and pinion mechanism translates the rotational motion of the steering wheel into lateral movement of the front wheels with exceptional accuracy, ensuring optimal tracking and stability. The pinion, a finely machined gear tooth assembly, meshes seamlessly with the linear rack, minimizing backlash and ensuring consistent feedback, which is particularly important for the 750Li s sport-tuned suspension and adaptive damping systems. The hydraulic unit is integrated into the rack, incorporating a **steering pump and pressure regulator** to maintain optimal fluid pressure, further enhancing the system s efficiency and longevity.

This steering gear is engineered to meet BMW s stringent quality standards, featuring **laser-welded joints, corrosion-resistant coatings, and precision-balanced components** to prevent premature failure and ensure a quiet, vibration-free operation. The design also incorporates **sealed bearings and bushings** to reduce friction and wear, contributing to the overall durability of the assembly. For the discerning owner of a 750Li, this part is not merely a functional component but a testament to BMW s commitment to engineering excellence, blending performance, comfort, and luxury in every detail.

Whether installed during routine maintenance or as part of a full suspension refresh, this **OEM-quality hydraulic power steering rack and pinion** ensures that the 750Li retains its legendary driving dynamics, from effortless highway cruising to the sharp, communicative feel of the steering under dynamic cornering. Its compatibility with the E65 and E66 platforms including models equipped with either the **N62 or N63 inline-six engines** makes it an essential upgrade or replacement for those seeking to restore or enhance their vehicle s original performance characteristics. With its robust construction and meticulous engineering, this steering gear is a cornerstone of the 750Li s reputation for refinement and driving pleasure.

### **Pros and Cons of Buying a BMW 750Li (E65/E66, 02-08, 6777259 Hydraulic Power Steering Gear Rack & Pinion)**

#### **Pros**

1. **Luxury and Comfort**

The 750Li is a flagship BMW, offering premium materials, refined cabin acoustics, and a spacious, high-end interior. The seating position is commanding, and the ride is smooth, making it ideal for long-distance driving.

2. **Power and Performance**

With a **6.0L V12 (550-617 hp)** or **6.0L Twin Turbo V8 (507 hp)**, this car delivers exceptional acceleration and top-speed capability. The E65/E66 models (pre-facelift) are particularly sought after for their raw, unfiltered power delivery.

3. **Reliability of Core Components**

- The **hydraulic power steering (HPS) system** (rack & pinion) is robust and less prone to electronic failures compared to later electric power steering (EPS) models.

- The **V12 engine** (N73) is known for longevity if maintained properly, though it requires high-quality fuel and regular oil changes.

- The **automatic transmissions (ZF 5HP24 or 6HP21)** are durable, especially the **6-speed** in later models.

4. **Classic BMW Driving Experience**

The manual shift (if available) and the **steering feel** (despite being hydraulic) provide a more engaging drive than modern EPS systems. The suspension tuning is well-balanced for both comfort and road-hugging precision.

5. **Resale Value and Collectibility**

The **E65/E66 750Li (especially the V12)** is highly desirable among BMW enthusiasts, meaning it retains strong resale value. Early facelift models (pre-2008) are particularly prized.

6. **Customization Potential**

BMW s **M3/M5/M6 tuning** and aftermarket support allow for significant upgrades, including **suspension, exhaust, and engine modifications**, though these can be costly.

7. **Low-Mileage Examples Available**

Many of these cars were sold in limited numbers, so well-maintained, low-mileage examples (under 50,000 miles) are sometimes found, offering near-new reliability.

---

#### **Cons**

1. **High Maintenance Costs**

- **Engine:** The **V12 (N73)** and **V8 (M73)** require **premium fuel (91 octane)**, high-quality oil changes (every 5,000-7,500 miles), and potential **valve cover, gasket, and oil pump replacements** as it ages.

- **Transmission:** While robust, **automatic transmissions** can fail without proper fluid changes (every 60,000 miles).

- **Brakes & Suspension:** **Brake pads, rotors, and bushings** wear out quickly due to the car s weight and performance nature.

2. **Fuel Consumption and Running Costs**

- The **V12 averages 12-15 MPG**, while the **V8 does slightly better (14-17 MPG)**.

- **Insurance** is expensive due to the car s value and performance capabilities.

- **Tires** (high-performance or run-flat) add to ongoing costs.

3. **Complexity and Expertise Required**

- BMW s **electronic systems (iDrive, engine management, ABS)** can be finicky and require a **well-versed mechanic** for repairs.

- **Hydraulic power steering leaks** (though rare) can be messy and costly to fix.

- **Electrical gremlins** (e.g., sensor failures, wiring issues) are common in older BMWs.

4. **Weight and Handling**

- The **750Li is heavy (4,500 lbs)**, making it **less nimble** than smaller BMWs.

- While the **E65/E66 has a more direct steering feel than later models**, it still lacks the precision of modern systems.

5. **Common Wear Items**

- **Exhaust manifolds** (V12) can crack over time.

- **Water pump and thermostat failures** are frequent in these engines.

- **Rear differential seals** may leak fluid if not maintained.

- **Sunroof leaks** are a known issue in some models.

6. **Depreciation (Despite Resale Value)**

- While the **E65/E66 holds value well**, it still depreciates significantly over time. A **brand-new 750Li in 2002 would cost $150K **, but a **used example today may be worth 30-50% less** depending on condition.

7. **Environmental and Practical Limitations**

- **Low fuel efficiency** makes it impractical for daily commuting in urban areas.

- **Parking and maneuverability** can be challenging due to size.

- **Modern tech limitations** (no Apple CarPlay/Android Auto, outdated infotainment) may frustrate some buyers.

---

### **Ending Conclusion**

The **BMW 750Li (E65/E66, 02-08, V12 or V8, hydraulic power steering)** is a **fantastic luxury grand tourer** for the right buyer someone who prioritizes **performance, prestige, and a classic BMW driving experience** over modern convenience and fuel efficiency. It is **best suited for:**

- **Weekend drivers** who enjoy long highway cruises and occasional track days.

- **Collectors and enthusiasts** who appreciate the car s rarity and potential appreciation.

- **Those with mechanical knowledge or access to a trusted BMW specialist** for maintenance.

- **Daily drivers** due to high running costs and complexity.

- **Budget-conscious buyers** expect **$50K ** for a decent example, with **$2K /month** in maintenance if not properly maintained.

- **Those who prefer modern tech** the infotainment and electronics are outdated by today s standards.
