The **Ford D7TP-3590-GA Power Steering Pitman Arm** is a meticulously crafted, high-performance component designed exclusively for the **1977 1979 Ford F-250 Super Duty 4x4** trucks, ensuring precise and reliable steering control in even the most demanding off-road and heavy-duty applications. This direct-replacement part is engineered to match the exact specifications of the original equipment manufacturer (OEM), featuring a robust **galvanized steel construction** that resists corrosion, rust, and wear, making it ideal for vehicles operating in harsh environments or those subjected to frequent exposure to moisture, dirt, or salt.

Whether you're hauling heavy loads, navigating rough terrain, or simply seeking long-term reliability, this pitman arm delivers the strength and performance needed to keep your **F-250 4x4** steering system in optimal condition. Perfect for restoration projects, performance upgrades, or routine maintenance, this part is a seamless fit for the **D7TP steering gear assembly**, offering a direct upgrade over worn or damaged OEM components while maintaining full compatibility with the truck s original steering linkage and tie rod ends.

### **Pros and Cons of Buying a 1977-79 Ford F-250 D7TP-3590-GA 4x4 with Power Steering Pitman Arm**

#### **Pros**

1. **Classic Ford Durability** The F-250 from this era was built to last, with a reputation for rugged reliability, especially in 4x4 configurations. Many original engines and transmissions survive with proper maintenance.

2. **Strong Engine Options** The D7TP-3590-GA designation suggests a **351 Cleveland V8**, which was a powerful and durable engine for its time. With proper care, these engines can easily exceed 200,000 miles.

3. **4x4 Capability** A true off-road machine, this truck was designed for heavy-duty work and rough terrain. The 4x4 system, if maintained, remains functional for light to moderate off-roading or farm use.

4. **Power Steering** Unlike manual steering systems, power steering makes the truck easier to drive, especially useful for heavy loads or long hauls.

5. **Pitman Arm Availability** The fact that a replacement pitman arm is available means the steering system is repairable, which is a good sign that major components are still supported.

6. **Potential for Restoration** If the truck is in rough shape, it can be restored to like-new condition with the right effort and budget. Classic Ford trucks hold value among enthusiasts.

7. **Lower Purchase Price** Compared to modern trucks, a 1977-79 F-250 will cost significantly less, making it an attractive option for those on a budget.

8. **Parts and Community Support** Ford parts are still widely available, and there is a strong community of owners and mechanics familiar with this era.

#### **Cons**

1. **Age and Wear** At nearly 50 years old, the truck will likely have significant wear in the suspension, drivetrain, and body. Rust, worn bushings, and failing seals are common issues.

2. **High Maintenance Costs** Older trucks require more frequent maintenance than modern vehicles. Expect to replace fluids, belts, hoses, and wear items like ball joints, shocks, and brakes.

3. **Potential Rust Issues** If the truck was exposed to moisture or poor storage, rust can compromise structural integrity, especially in the frame, axles, and undercarriage.

4. **Electrical System Reliability** Older wiring and components may fail over time, leading to intermittent electrical issues. The alternator, starter, and battery may need frequent attention.

5. **Fuel and Emissions Concerns** Modern fuel standards mean older trucks may not run well on today s gasoline blends. Emissions systems (if equipped) may also require modifications to comply with current regulations.

6. **Limited Modern Safety Features** No airbags, modern seat belts, or electronic stability control. Driving conditions are less safe compared to today s standards.

7. **Resale Value** While classic trucks appreciate among collectors, they do not hold value like newer trucks. If you plan to sell later, expect a lower return on investment.

8. **Driving Experience** The ride will be firmer and noisier than modern trucks. Interior comfort and noise insulation are minimal compared to today s standards.

9. **Potential Hidden Problems** Without a thorough inspection, issues like a leaking differential, worn universal joints, or a failing transfer case may not be immediately obvious.

10. **Limited Availability of Modern Upgrades** While aftermarket parts exist, integrating modern technology (e.g., fuel injection, turbocharging, or advanced suspension) can be challenging and costly.

### **Conclusion**

- **Enjoy classic trucks** and don t mind restoring or maintaining a vintage vehicle.

- **Need a rugged, off-road-capable work truck** for light-duty tasks (e.g., farming, hauling, or weekend adventures).

---

### **Recommendation**

1. **Get a Professional Inspection** Have a trusted mechanic or Ford specialist thoroughly check the engine, transmission, drivetrain, suspension, and electrical system before buying.

2. **Address Rust Immediately** If rust is present, treat it early to prevent structural failure. Consider a full undercarriage rustproofing treatment.

- **Suspension bushings** (control arms, sway bar links)

- **Shocks/struts**

- **Universal joints and driveshafts**

- **Differential seals and fluid**

- **Brakes and brake lines**

4. **Upgrade the Engine if Needed** If the 351 Cleveland is running poorly, consider a **performance rebuild or swap** (e.g., a 302 or 351 Windsor) for better reliability.

5. **Modernize Where Possible** Installing a **modern fuel pump, alternator, and battery** can improve reliability. Consider upgrading the **exhaust system** for better performance and noise reduction.

6. **Use It Regularly** Older trucks suffer from neglect if left unused. If possible, keep it in light service to maintain components.

7. **Budget for Restoration** If the truck is in poor condition, factor in **$3,000 $10,000 ** for a full restoration, depending on its current state.

8. **Join a Ford Enthusiast Community** Groups like **Ford Truck Club (FTC)** or local classic Ford forums can provide valuable advice, parts sources, and restoration tips.

**Final Verdict:** This truck is a **fantastic project vehicle** for those who appreciate classic Ford engineering and don t mind the challenges of ownership.
