**Pros and Cons of buying a Dorman 746-740 Liftgate Lock Actuator**

The Dorman 746-740 is a common aftermarket replacement for liftgate lock actuators found in vehicles like the Ford F-150, Escape, and Taurus, among others. Below is a detailed breakdown of its advantages and disadvantages.

### **Pros**

1. **Compatibility and Fitment**

The Dorman 746-740 is designed as a direct replacement for many OEM (Original Equipment Manufacturer) liftgate lock actuators, particularly those used in Ford vehicles from the late 1990s through the early 2010s. This means it should fit without major modifications, provided the vehicle s wiring and mounting points align with the original part.

2. **Reliability and Durability**

Dorman is a well-established brand known for producing high-quality automotive replacement parts. The 746-740 actuator is built to withstand regular use, reducing the likelihood of premature failure compared to cheaper, no-name alternatives. Many users report that it lasts for the lifespan of the vehicle, especially if installed correctly.

3. **Ease of Installation**

The part is relatively straightforward to install, especially for those with basic mechanical skills. It typically requires removing the liftgate, disconnecting the wiring harness, and replacing the old actuator with the new one. Dorman provides clear instructions, and the part is often sold with necessary hardware (e.g., bolts, clips). However, some users may need to adapt wiring or brackets if the vehicle s design differs slightly from the standard fitment.

4. **Cost-Effective Solution**

Compared to purchasing an OEM part (which can be significantly more expensive), the Dorman 746-740 offers a budget-friendly alternative without sacrificing quality. Pricing is competitive, and the part is widely available through auto parts stores, online retailers, and dealerships.

5. **Warranty and Support**

Dorman parts often come with a warranty (typically 12 24 months), providing some assurance against defects. Additionally, Dorman is backed by major automotive retailers, meaning technical support and return policies are generally reliable if issues arise.

6. **Positive User Feedback**

Many reviews from mechanics and DIY enthusiasts highlight the 746-740 s performance, praising its smooth operation and longevity. Fewer complaints about failure compared to other aftermarket brands suggest it is a trusted choice.

### **Cons**

1. **Limited Vehicle Compatibility**

While the 746-740 fits many Ford models, it is not universal. Some vehicles may require a different part number or additional modifications (e.g., wiring harness adjustments). Always verify compatibility with your specific vehicle s year, model, and trim before purchasing to avoid mismatches.

2. **Potential Wiring or Electrical Issues**

If the original wiring harness is damaged or corroded, replacing just the actuator may not resolve underlying electrical problems. Users might need to inspect or replace wiring, connectors, or the liftgate switch itself. In rare cases, the new actuator could draw too much current, potentially frying related components if the vehicle s electrical system is not robust.

3. **Quality Control Variability**

While Dorman is generally reliable, like all aftermarket parts, there is a small chance of receiving a defective unit. This risk is mitigated by purchasing from reputable sellers (e.g., RockAuto, Amazon, or local auto parts stores with return policies). Always check for reviews or return the part if it fails upon arrival.

4. **No Direct OEM Performance**

The Dorman 746-740 is a functional replacement, not an upgraded part. It may not offer any performance improvements over the original (e.g., faster engagement, quieter operation) unless the original was faulty. If you re looking for enhanced features, you may need to explore specialized aftermarket options.

5. **Installation Challenges for Non-Mechanics**

While the installation is manageable for those with basic tools, some users may encounter difficulties if the liftgate or wiring is particularly tricky to access. Rust, tight spaces, or unusual mounting points can complicate the process. If unsure, consulting a professional mechanic may be advisable.

6. **Limited Customization**

Unlike some high-end aftermarket actuators, the Dorman 746-740 does not offer customizable features (e.g., adjustable tension, different engagement speeds). It is a "one-size-fits-most" solution rather than a tailored upgrade.

---

### **Conclusion**

The Dorman 746-740 liftgate lock actuator is a solid, reliable choice for replacing a faulty or worn-out original part in compatible Ford vehicles. Its strengths lie in its compatibility, durability, ease of installation, and cost-effectiveness, making it a practical option for both DIYers and professionals. However, potential buyers should ensure their vehicle s fitment matches the part number, address any underlying wiring issues, and be prepared for minor installation challenges if they lack mechanical experience.

For most users seeking a straightforward, high-quality replacement, the Dorman 746-740 is a recommended purchase. If the vehicle s electrical system is unreliable or if customization is a priority, additional research or professional assistance may be necessary.

### **Recommendation**

- Your vehicle is a compatible Ford model (verify with the part number and your vehicle s specifics).

- You need a direct replacement for a non-functioning liftgate actuator.

- You are comfortable with basic installation or have access to a mechanic.

- You prioritize reliability and cost efficiency over specialized features.

- Your vehicle s wiring or liftgate mechanism is severely damaged or unusual.

- You suspect the issue lies elsewhere (e.g., liftgate switch, ground connections).

- You want an upgraded actuator with additional features (e.g., faster response, quieter operation).

For peace of mind, purchase from a trusted retailer with a return policy and consider checking forums or reviews specific to your vehicle model for additional insights.
