Review BUICK Power Liftgate Strut Left Right Oem fits ENCLAVE 2018–2021

The **Buick 84771388 2018-2021 Enclave Power Liftgate Strut (Left & Right, Part #84243984)** is a precision-engineered component designed to deliver seamless, effortless operation of the Enclave s signature power liftgate system. This high-performance strut is a critical element in ensuring smooth, quiet, and reliable gate movement, whether opening, closing, or holding the gate in an open position. Crafted from durable, corrosion-resistant materials, the strut is built to withstand the demands of daily use, including exposure to varying weather conditions, road debris, and the weight of the gate itself. Its robust construction incorporates a sealed hydraulic or gas-charged mechanism, depending on the specific model year, which provides consistent resistance and support, preventing sagging or uneven closure. The left and right struts are engineered to work in tandem, ensuring balanced gate movement and eliminating any potential binding or misalignment that could lead to premature wear or operational issues. Whether you re navigating tight parking spaces, loading cargo, or simply accessing the rear of your vehicle, this strut guarantees a smooth, effortless experience with minimal effort from the driver. Ideal for both original equipment replacement and aftermarket upgrades, this part is a direct fit for the 2018 through 2021 Buick Enclave, maintaining the vehicle s premium feel and functionality. Proper installation is essential to ensure optimal performance, and using genuine Buick components like this strut helps preserve the integrity of the liftgate mechanism, extending the lifespan of the entire system.

Buying the **Buick Enclave (2018-2021) with Power Liftgate Struts (Left & Right, Part Numbers 84771388 and 84243984)** can be a practical solution for certain owners, but it also comes with trade-offs. Below is a detailed breakdown of the pros and cons, followed by a conclusion and recommendation.

---

### **Pros of buying a Liftgate Struts**

1. **Improved Liftgate Functionality**

The power liftgate struts (also called "gate assist" or "gate struts") enhance the ease of opening and closing the liftgate, especially when carrying heavy items like groceries, luggage, or outdoor gear. This can reduce strain on the user s back and arms, making the vehicle more user-friendly.

2. **Prevents Premature Wear on the Liftgate Mechanism**

Over time, the liftgate s hydraulic or electric system can become sluggish or fail entirely due to wear. Installing new struts can restore smooth operation and extend the life of the liftgate s internal components, such as the hydraulic pump or electric motor.

3. **Compatibility with Aftermarket Modifications**

If you ve added aftermarket features like a roof rack, cargo organizers, or heavy-duty side steps, the liftgate may struggle to close properly. New struts can compensate for added weight and improve functionality.

4. **Potential Resale Value Boost**

A well-maintained liftgate with properly functioning struts can make the vehicle more appealing to buyers, as liftgate issues are a common complaint in used SUVs. This could help justify a slightly higher resale price.

5. **DIY-Friendly Installation (For Some Owners)**

While the installation requires basic mechanical skills and tools, many owners find it manageable with step-by-step guides. If you re comfortable with minor automotive repairs, this can save labor costs.

6. **Cost-Effective Compared to Full Liftgate Replacement**

Replacing just the struts is far cheaper than overhauling or replacing the entire liftgate assembly, which could cost several hundred dollars more.

---

### **Cons of buying a Liftgate Struts**

1. **Limited Longevity of the Struts Themselves**

While the struts improve liftgate operation, they are not permanent fixes. Like any mechanical part, they can wear out over time, especially if the liftgate is used frequently or exposed to harsh conditions (e.g., extreme heat, cold, or moisture). Expect them to last **5 10 years** with normal use, though some may degrade faster.

2. **Potential for Incompatibility or Fit Issues**

Counterfeit or low-quality struts may not fit perfectly, leading to misalignment, noise, or premature failure. Always verify that the part numbers (84771388 and 84243984) match your vehicle s year and trim level. Buying from a reputable dealer or OEM supplier reduces this risk.

3. **No Guarantee Against Underlying Liftgate Problems**

If the liftgate s hydraulic or electric system is failing, new struts alone won t fix it. Symptoms like slow opening, erratic movement, or complete failure of the liftgate may persist if the root cause (e.g., a faulty motor, leaking hydraulic lines, or electrical issues) isn t addressed. A diagnostic check may be necessary before purchasing.

4. **Installation Challenges**

The liftgate struts are located behind the liftgate panel and require removing the trim and possibly the liftgate itself for installation. This can be time-consuming and may void warranties if done improperly. Some owners may need to seek professional help, adding to the cost.

5. **Cost Consideration Relative to Other Fixes**

While the struts are affordable (typically **$50 $150 each** depending on source), if the liftgate has other issues (e.g., a failing motor or damaged seals), the total repair cost could exceed the value of the struts alone. In such cases, a full liftgate replacement might be more cost-effective in the long run.

6. **Environmental and Safety Concerns**

If the liftgate is already damaged (e.g., bent, cracked, or with electrical faults), simply replacing the struts could pose a safety risk. The liftgate might not close securely, leading to potential hazards (e.g., sudden opening while driving). Always inspect the liftgate mechanism thoroughly before installation.

---

### **Conclusion**

Buying the **Buick Enclave (2018 2021) power liftgate struts (84771388 and 84243984)** is a **practical and cost-effective solution** for owners experiencing minor liftgate stiffness or slow operation. The struts improve convenience and can prevent further wear on the liftgate system. However, they are not a universal fix underlying mechanical or electrical issues may still require attention.

If your liftgate is **functional but sluggish**, the struts are a worthwhile upgrade. If the liftgate **doesn t open/close at all** or exhibits erratic behavior, further diagnostics (e.g., checking the hydraulic pump, electric motor, or wiring) are essential before purchasing struts. In severe cases, a full liftgate replacement may be necessary.

---

### **Recommendation**

1. **Verify the Issue**: Confirm that the problem is solely due to worn struts and not a failing liftgate motor, hydraulic system, or electrical components. A mechanic can diagnose this for $100 $150.

2. **Source Quality Parts**: Purchase **OEM or high-quality aftermarket struts** from a trusted supplier (e.g., RockAuto, Buick dealership parts department, or reputable online retailers). Avoid cheap knockoffs that may fail quickly.

3. **DIY or Professional Installation**: If you re comfortable with automotive repairs, proceed with installation. Otherwise, hire a mechanic ( $100 $200 labor) to ensure proper fitting and alignment.

4. **Consider Alternatives**: If the liftgate is old or frequently problematic, weigh the cost of struts against a **full liftgate replacement** ( $500 $1,000) or a **used/refurbished liftgate** ( $300 $600).

5. **Maintain the Liftgate**: After installation, lubricate the struts periodically (if applicable) and avoid overloading the liftgate to extend their lifespan.

For **minor liftgate performance issues**, the struts are a **smart, budget-friendly upgrade**. For **major failures**, prioritize diagnosing the root cause before committing to parts. If the liftgate is otherwise in good condition, the struts will likely provide **noticeable improvement** for a few years.
