### Pros and Cons of buying a Subaru 57735FL000 Upper Seal

---

### **Pros of Buying This Part**

1. **Direct Fitment for Specific Models**

- The **57735FL000** is a **genuine or high-quality aftermarket replacement** designed specifically for Subaru vehicles, ensuring compatibility with the **upper control arm or subframe mount** in models like the **2013 2020 Outback/Forester/Legacy/Crosstrek**.

- Avoids the risk of **misalignment or improper fit** that can occur with generic parts.

2. **Improves Drivability and Comfort**

- A **worn or failing upper seal/bushing** can cause **clunks, rattles, or excessive movement** in the suspension, leading to a rough ride.

- Replacing it restores **smooth handling, reduces vibrations**, and eliminates **unwanted noises** (especially over bumps or when accelerating/decelerating).

- Helps maintain **proper wheel alignment**, preventing uneven tire wear.

3. **Prevents Further Damage**

- A failing upper seal can lead to **suspension misalignment**, **transmission issues (in CVT-equipped cars)**, or even **engine mounts failing** if the problem is ignored.

- Replacing it **proactively** can save money on **costlier repairs** down the line (e.g., **subframe damage, transmission problems, or engine mount replacement**).

4. **Durability and Longevity**

- High-quality **rubber or polyurethane bushings** (depending on the part) are designed to **last longer than OEM components** in some cases, especially if the vehicle sees **off-road use or rough roads**.

- Some aftermarket options include **reinforced steel inserts** for better durability.

5. **Easy Installation (For DIYers)**

- While **suspension work can be labor-intensive**, the **57735FL000** is often a **straightforward replacement** if you have basic mechanical skills.

- Many owners report that with the **right tools (torque wrench, C-clamp, suspension alignment tool)**, it can be done in **2 4 hours**.

- **Genuine Subaru parts** come with **clear instructions**, while reputable aftermarket brands (e.g., **Duralast, Moroso, or ACDelco**) also provide **detailed guides**.

6. **Cost-Effective Compared to Full Suspension Rebuild**

- Replacing just the **upper seal/bushing** is **far cheaper** than a **full suspension overhaul** or **subframe replacement**.

- Prices typically range from **$50 $150 for the part**, with labor adding **$100 $250** depending on the shop.

7. **Maintains Resale Value**

- A **well-maintained suspension** is a **key selling point** for used Subarus, as buyers expect **smooth handling and no unusual noises**.

---

### **Cons of Buying This Part**

1. **Potential for Counterfeit or Low-Quality Parts**

- **Cheap aftermarket parts** (especially from unknown sellers) may **wear out quickly** or **fail prematurely**, leading to **recurring issues**.

- **Genuine Subaru parts** are more expensive but **reliable**, while **no-name brands** may not last as long.

- **Always buy from reputable suppliers** (e.g., **RockAuto, Subaru dealers, or trusted online marketplaces**) to avoid fakes.

2. **Labor-Intensive Installation (For Some)**

- While the part itself is **relatively simple**, the **location and access** can make installation **challenging**.

- Some vehicles require **removing the subframe, sway bar, or even the engine mount** to access the upper seal, which can be **time-consuming**.

- **Misalignment during installation** can lead to **vibration or handling issues**, so **precision is key**.

3. **May Require Additional Repairs**

- If the **upper seal has been failing for a while**, other components (like **ball joints, control arms, or subframe mounts**) may also be **worn out**.

- A **full suspension inspection** may be needed to ensure **no other parts need replacement**.

- In **CVT-equipped vehicles**, a **suspension misalignment** can sometimes **affect transmission performance**, requiring a **transmission fluid flush or alignment**.

4. **Cost of Professional Installation**

- While DIY is possible, **most people opt for a mechanic**, adding **$100 $250 in labor costs**.

- Some shops may **upsell additional work** (e.g., **alignment, subframe bolts, or other bushings**) if they find related issues.

- **Independent shops** may charge less than **dealerships**, but quality varies.

5. **Risk of Incorrect Part Selection**

- Subaru has **multiple upper seal variants** (e.g., **57735FL000 vs. 57735FL001**), and **mixing up part numbers** can lead to **poor fitment**.

- Some **aftermarket parts may not match the exact dimensions**, causing **looseness or binding**.

- **Always verify the part number against your vehicle s year, model, and engine type** before purchasing.

6. **Potential for Recurring Issues (If Underlying Problems Exist)**

- If the **failure was due to a design flaw** (e.g., **weak OEM bushings in certain Subaru models**) or **poor road conditions**, the **new part may fail again** if the root cause isn t addressed.

- Some owners report that **polyurethane bushings** (common in aftermarket) can **wear out faster** than **rubber bushings** in extreme conditions.

7. **Alignment Required After Installation**

- Replacing a **suspension bushing** almost always **disrupts wheel alignment**.

- A **post-repair alignment** is **highly recommended** to prevent **uneven tire wear** and **poor handling**.

- Alignment costs **$50 $100**, adding to the **total expense**.
