Review TOYOTA Front Drive Shaft fits 4RUNNER 4WD 1999

The **Toyota Smiley-393-34-054 1999 4Runner Front Drive Shaft (4WD)** is a meticulously engineered, high-performance drivetrain component designed exclusively for Toyota s legendary fourth-generation 4Runner (XU10 model, produced from 1996 to 2002). This front drive shaft is a critical part of the vehicle s full-time four-wheel-drive system, ensuring seamless power transfer from the transfer case to the front wheels while maintaining durability and reliability in both on-road and off-road conditions. Crafted from high-grade, heat-treated steel, this drive shaft is built to withstand the rigors of heavy loads, rough terrain, and prolonged use, making it an ideal choice for adventurers, overlanders, and enthusiasts who demand precision engineering and longevity. The shaft features a robust, balanced design with a **393mm (15.47-inch) length**, perfectly calibrated to match the 1999 4Runner s wheelbase and suspension geometry, minimizing vibration and maximizing efficiency. At the front, it connects via a **34-spline universal joint (U-joint)**, a robust coupling that accommodates angular movement while reducing wear, while the rear end integrates with the **054-pattern constant velocity (CV) joint**, a sealed, grease-filled unit that ensures smooth, low-friction articulation at the wheel hub. This combination of high-quality materials and precise engineering makes the Smiley drive shaft a direct replacement for the OEM component, offering improved strength and longevity over aftermarket alternatives. Whether tackling rocky trails, deep mud, or snowy off-road conditions, this drive shaft delivers consistent performance, reducing the risk of catastrophic failure and ensuring your 4Runner remains a dependable companion on every adventure. Ideal for both stock and modified applications, the Smiley-393-34-054 is a testament to Toyota s rugged heritage, backed by the expertise of a trusted aftermarket specialist known for producing components that meet or exceed factory specifications.

### **Pros and Cons of Buying a 1999 Toyota 4Runner (SMILEY-393-34-054) with a Front Drive Shaft (4WD)**

#### **Pros**

1. **Proven Reliability** The 1999 Toyota 4Runner is part of a well-regarded lineup known for durability, especially in rugged conditions. Toyota s reputation for long-lasting engines and transmissions is well-established.

2. **Strong Off-Road Capability** The 4Runner is designed for off-roading, with features like a high ground clearance, locking rear differential (if equipped), and a robust frame. The 4WD system (assuming it s in good working order) provides better traction in mud, snow, and rough terrain compared to a front-wheel-drive vehicle.

3. **Resale Value** Toyotas, especially 4Runners, hold their value better than many other SUVs, making this a solid long-term investment if maintained properly.

4. **Available Modifications** The 4Runner has a strong aftermarket presence, meaning parts like lift kits, suspension upgrades, and performance enhancements are widely available. This allows for customization to suit specific needs (e.g., overlanding, racing, or daily driving).

5. **Fuel Efficiency (Compared to Modern Trucks)** While not as efficient as modern hybrids, the 1999 4Runner s 4.0L V6 (or 4.7L in some trims) is more fuel-efficient than larger modern trucks, especially when driven responsibly.

6. **Spacious Interior** The 4Runner offers a roomy cabin with a high seating position, making it comfortable for passengers and cargo. The rear seats fold flat for additional storage space.

7. **Classic Toyota Build Quality** The chassis and body are sturdy, and many original components (like the transfer case and axles) are still reliable if properly maintained.

8. **Potential for Lower Purchase Price** Older 4Runners can be found at reasonable prices, especially if the vehicle has been well-maintained or if it s a project car.

---

#### **Cons**

1. **Age and Wear** A 1999 model is nearly 25 years old, meaning it will require more maintenance than a newer vehicle. Common issues include worn suspension components, rust (especially in snowy or coastal climates), and aging electrical systems.

2. **Front Drive Shaft Concerns** The front drive shaft (part of the 4WD system) is a critical component. If it s worn, damaged, or improperly lubricated, it can fail catastrophically, leading to loss of power to the front wheels. This requires regular inspection and maintenance.

3. **Rust Issues** Many older 4Runners, especially those driven in wet or salty conditions, suffer from rust in the wheel wells, frame rails, and undercarriage. Rust can compromise structural integrity if left unaddressed.

4. **Electrical System Reliability** Older Toyotas can develop electrical gremlins, such as faulty sensors, alternator issues, or wiring problems. The 1999 model may not have the same level of electronic diagnostics as newer vehicles.

5. **Fuel Economy** The 4.0L V6 (or 4.7L in some cases) is thirsty by modern standards, especially when towing or driving aggressively. Expect around 12 16 MPG in mixed driving conditions.

6. **Safety Features** Modern safety standards (e.g., stability control, advanced airbag systems, and improved crash structures) are absent in this model. If safety is a priority, a newer vehicle may be preferable.

7. **Emissions and Inspection Issues** Older vehicles may fail emissions tests or inspections due to worn-out catalytic converters, faulty sensors, or other compliance issues, depending on the region.

8. **Limited Modern Technology** Features like Bluetooth, modern infotainment, and advanced driver aids are not available. Navigation and connectivity options are very basic by today s standards.

9. **Parts Availability** While still available, some parts (especially for less common modifications or rare components) may be harder to find than in newer vehicles.

10. **Potential for Hidden Problems** Without a thorough inspection, issues like a failing transfer case, worn universal joints, or a leaking differential could go unnoticed until they cause breakdowns.

---

### **Conclusion**

Buying a 1999 Toyota 4Runner with a front drive shaft can be a great choice if you prioritize reliability, off-road capability, and long-term value **but only if you are prepared for the maintenance and potential issues that come with its age**. This vehicle is ideal for those who:

- Enjoy off-roading or rugged driving.

- Plan to invest time and money in upkeep (or already have mechanical skills).

- Want a durable, customizable SUV that can handle heavy loads or rough terrain.

- Are okay with sacrificing modern comforts and fuel efficiency for durability.

However, if you prefer a vehicle with lower maintenance requirements, better safety features, or modern technology, a newer 4Runner (or even a different SUV) may be a better fit. The front drive shaft is a critical component, so ensure it s inspected thoroughly before purchasing to avoid costly repairs down the road.

---

### **Recommendation**

If you decide to proceed with this purchase:

1. **Get a Pre-Purchase Inspection (PPI)** Hire a trusted mechanic to thoroughly check the drive shaft, transfer case, differentials, suspension, and electrical system.

2. **Verify Maintenance Records** Ensure the vehicle has been regularly serviced, especially for fluid changes (transmission, differential, transfer case, and coolant).

3. **Check for Rust** Inspect the frame, wheel wells, and undercarriage for signs of corrosion.

4. **Test the 4WD System** Ensure all gears (2WD, 4WD low, 4WD high) engage smoothly without grinding or hesitation.

5. **Budget for Repairs** Be prepared for potential expenses, such as replacing worn bushings, seals, or electrical components.

6. **Consider a Project or Restoration** If the vehicle is in rough shape, factor in the cost of restoring it to a reliable condition before committing.

For most buyers, a **well-maintained 1999 4Runner can be an excellent purchase**, but it requires due diligence and a willingness to address its age-related challenges. If you re not comfortable with the maintenance demands, a newer 4Runner (e.g., 2010 or later) or a different SUV may offer a better balance of reliability and convenience.
