Review FORD Oem 2.3l Rear Drive Shaft Driveshaft Propeller fits EXPLORER 2020–2025

The **Ford L1M34K145AK 2020 2025 Explorer 2.3L Rear Drive Shaft (Driveshaft/Propeller Shaft)** is a precision-engineered, high-performance drivetrain component designed exclusively for Ford s second-generation 2.3L EcoBoost turbocharged four-cylinder engine, as found in the 2020 through 2025 Explorer models equipped with rear-wheel drive (RWD) or all-wheel drive (AWD) configurations. This driveshaft serves as the critical link between the transmission and the rear axle, transmitting torque from the engine and drivetrain to the wheels with exceptional efficiency while maintaining structural integrity under the demanding loads of modern turbocharged powertrains. Crafted from high-grade, heat-treated alloy steel, the shaft is engineered to withstand the intense rotational forces and vibrations generated by the 2.3L EcoBoost s aggressive power delivery, which produces up to **300 horsepower and 300 lb-ft of torque** in its most powerful iterations. The driveshaft features a **slip-yoke design** at the transmission end, allowing for smooth articulation during suspension movement, while the **constant-velocity (CV) or splined universal joint (U-joint) connection** at the axle end ensures precise power transfer even under dynamic driving conditions, such as sharp turns or uneven road surfaces. To enhance durability, the shaft is dynamically balanced to minimize wear on the transmission output bearing and differential input bearing, reducing noise and extending the lifespan of associated components. Additionally, the driveshaft is equipped with **protective rubber boots** at the joint ends to shield internal components from debris, moisture, and contaminants, which is particularly critical in off-road or rugged driving scenarios. This component is a direct replacement for Ford s original equipment (OEM) driveshaft, ensuring an exact fit with the **6F35 6-speed automatic transmission** and **Torsen-based AWD system** found in these Explorer models, while also accommodating minor variations in drivetrain tuning across the 2020 2025 model years. Whether installed in a high-performance trim like the **ST or Limited**, or a standard RWD/AWD configuration, this driveshaft delivers the reliability and performance expected from Ford s premium SUV lineup, making it an essential upgrade or replacement part for enthusiasts and professional mechanics alike.

### **Pros and Cons of Buying a 2020 2025 Ford Explorer (2.3L EcoBoost, Rear Drive Shaft/Propeller Shaft)**

#### **Pros**

1. **Reliability of the 2.3L EcoBoost Engine**

- The 2.3L EcoBoost is a well-proven turbocharged engine known for durability, especially in Ford s SUV lineup. It delivers strong performance (270 300 hp) while maintaining decent fuel efficiency (around 20 22 MPG combined).

- Fewer issues compared to older Ford V6 engines, though turbocharged engines require proper maintenance (oil changes, cooling system checks).

2. **Strong Resale Value**

- The Explorer holds its value better than many competitors, particularly in the mid-size SUV segment. This means you ll recoup more when trading it in later.

3. **Comfortable and Spacious Interior**

- The cabin is roomy, with good headroom and legroom for passengers. The seating is supportive, and the infotainment system (SYNC 3) is user-friendly, though some features require a subscription.

- Available premium materials (leather, wood trim) in higher trims enhance the feel.

4. **Good Safety Ratings**

- The Explorer earns high marks from the NHTSA and IIHS for crashworthiness, with standard features like forward collision warning, automatic emergency braking, and blind-spot monitoring.

- Available safety tech (like adaptive cruise control and lane-keeping assist) makes it a solid choice for families.

5. **Available AWD (Optional)**

- While the 2020 2025 models primarily come with rear-wheel drive (RWD) or front-wheel drive (FWD), the **AWD option** (on higher trims) provides better traction in snow or light off-road conditions. The RWD setup here is unusual for an Explorer most are FWD or AWD so if you prefer rear-wheel drive, this could be a niche advantage.

6. **Fuel Efficiency for a Mid-Size SUV**

- The 2.3L EcoBoost achieves ** 20 22 MPG combined**, which is decent for a vehicle in this class. Diesel alternatives (like the 3.0L Power Stroke) are more efficient but require different maintenance.

7. **Lower Maintenance Costs Than Competitors**

- Compared to luxury SUVs (e.g., BMW X5, Audi Q5) or high-performance trucks, the Explorer s maintenance costs are relatively modest. Routine services (oil changes, timing belt replacements) are straightforward.

8. **Available Tech and Convenience Features**

- Standard features include a **7-inch touchscreen**, Apple CarPlay/Android Auto, and available **360-degree cameras** (on higher trims).

- Comfort options like heated/ventilated seats, a power liftgate, and a premium sound system are available.

9. **Good Towing Capacity (On Higher Trims)**

- The **STL trim and above** can tow up to **5,000 lbs** with the proper package, making it useful for small trailers or light-duty towing.

10. **Ford s Warranty Coverage**

- The **battery warranty** is extended (up to 10 years/120,000 miles), and the **powertrain warranty** is standard (3 years/36,000 miles). This provides peace of mind for long-term ownership.

---

#### **Cons**

1. **Rear-Wheel Drive (RWD) is Uncommon for an Explorer**

- **Poor snow/ice traction** compared to AWD (unless you have winter tires).

- **Less engaging driving feel** RWD can be understeer-prone in aggressive driving.

- **Potential drivetrain wear** if not driven carefully on rough roads (propeller shaft stress).

- If you need **AWD for winter or off-road use**, this model is not ideal.

2. **Turbocharged Engine Maintenance Requirements**

- **Frequent oil changes** (every 5,000 7,500 miles for synthetic).

- **Coolant system checks** (turbochargers overheat if the cooling system fails).

- **Intake manifold gasket replacements** (a known issue in some years, though less common in 2020 models).

- If maintenance is neglected, turbo failure or engine damage can occur.

3. **Ride Quality Can Be Firm**

- The Explorer s suspension is **stiffer than competitors** (e.g., Honda Pilot, Toyota Highlander), leading to a less comfortable ride on rough roads.

- The **rear-drive setup may make the ride feel less balanced** compared to FWD or AWD models.

4. **Infotainment System Limitations**

- The **SYNC 3 system** is functional but **laggy at times**, and some advanced features (like wireless CarPlay) require a subscription.

- The **screen resolution is lower** than competitors (e.g., Chevrolet Traverse, Nissan Pathfinder).

5. **Interior Build Quality Varies by Trim**

- Lower trims (e.g., **XLT**) feel **cheaper** with plastic trim and less sound insulation.

- Higher trims (e.g., **Limited, Platinum**) improve but still don t match **luxury SUVs** (e.g., Volvo XC90, Mercedes GL-Class).

6. **Resale Depreciation (Compared to Competitors)**

- While the Explorer holds value well, **luxury brands (Lexus, Toyota, Honda)** often depreciate slower.

- If you plan to sell early, you may not recoup as much as a **Toyota Highlander or Honda Pilot**.

7. **Transmission Issues (Reported in Some Models)**

- A few owners report **rough shifting or delayed engagement** in the **10-speed automatic**, though Ford has improved reliability in recent years.

- If the transmission is not maintained properly, **premature wear** can occur.

8. **Limited Off-Road Capability**

- The **standard RWD setup is not designed for off-roading**. Even with AWD options, the Explorer lacks **locking differentials, skid plates, or high ground clearance** found in **Ford s Bronco or F-150 Raptor**.

- If you need **serious off-road ability**, consider a **Toyota 4Runner, Jeep Wrangler, or Ford Bronco**.

9. **Fuel Pump Failure Risk (Known Issue in Some EcoBoost Models)**

- Some **2.3L EcoBoost engines** (especially pre-2020) have had **fuel pump failures**, leading to stalling or no-start conditions.

- **Solution:** Ensure the vehicle has had **fuel system maintenance** and consider a **pre-purchase inspection**.

10. **Higher Trim Pricing for Features**

- To get **premium features** (leather seats, sunroof, advanced safety), you often need to **upgrade to higher trims (Limited, Platinum)**, which increases cost.

---

### **Conclusion**

**Reliability** (if maintained properly)

**Good fuel efficiency for an SUV**

**Spacious, comfortable interior**

**Strong resale value**

**RWD preference (though unusual for this model)**

**Winter/snow driving** (RWD is a major drawback)

**Off-road or rugged use** (lack of AWD/4WD and protection)

**Luxury-focused buyers** (interior feels basic compared to competitors)

**Those who want a more engaging drive** (RWD is understeer-heavy)

---

### **Recommendation**

- You **live in a warm climate** and don t need AWD.

- You **prioritize reliability and fuel efficiency** over off-road capability.

- You **prefer RWD** (though this is rare for an Explorer).

- You **plan to keep it for 5 years** (to maximize resale value).

- You **budget for maintenance** (oil changes, turbo care).

- You **need AWD for snow or rough roads**.

- You **plan to tow heavily** (stick to **STL or higher trims**).

- You **want a more premium feel** (consider a **Lexus RX, Toyota Highlander, or Honda Pilot**).

- You **drive aggressively** (RWD may feel unstable in spirited driving).

- **2020 2025 Ford Explorer (AWD, 3.0L EcoBoost)** Better for winter driving.

- **Toyota Highlander (AWD, V6)** More refined, better resale.

- **Honda Pilot (AWD, V6)** More comfortable, reliable.

- **Chevrolet Traverse (FWD/AWD
