---

### **Pros of the InMotion WS313842 Pitman Shaft Seal**

1. **Direct Fitment for TJ Wranglers**

The InMotion WS313842 is specifically designed as an **OEM replacement** for the pitman shaft seal in Jeep TJ models. This means it should align perfectly with the steering gear housing without requiring modifications, reducing the risk of installation errors.

2. **High-Quality Rubber Compound**

InMotion uses a **durable rubber compound** that is resistant to oil, grease, and environmental degradation. This helps prevent leaks over time, which is critical for maintaining proper steering function and preventing contamination of the steering system.

3. **Easy Installation**

The seal is designed for straightforward replacement, typically requiring only basic tools. Many users report that it can be installed in **under an hour** with proper preparation, making it a convenient DIY-friendly part.

4. **Affordable Price Point**

Compared to some aftermarket or OEM alternatives, the InMotion seal is **reasonably priced**, offering good value for the performance and longevity it provides. It is often cheaper than purchasing an entire steering gear assembly if only the seal is worn.

5. **Widely Available**

InMotion is a well-known brand in the automotive aftermarket, and this part is **easily found** at most Jeep specialty shops, online retailers (Amazon, RockAuto, Summit Racing), and through Jeep forums. Availability reduces the risk of delays in ordering.

6. **Positive User Feedback**

Many TJ Wrangler owners report **satisfactory performance** with this seal, citing fewer leaks and extended service life compared to cheaper or lower-quality alternatives. Reviews often highlight its reliability in preventing grease leaks that can damage the steering boot and other components.

7. **Compatibility with Common Modifications**

Since it is an OEM-style seal, it works well with stock TJ Wranglers as well as those with **minor steering modifications** (e.g., upgraded steering gear, but not extreme aftermarket setups). It is not designed for heavily modified or off-road-specific steering systems.

### **Cons of the InMotion WS313842 Pitman Shaft Seal**

1. **Not a Premium or High-End Seal**

While the InMotion seal is reliable, it is **not considered a "premium" or "high-performance" part**. If you are running your TJ in **extreme off-road conditions** or subjecting the steering to heavy loads (e.g., frequent rock crawling, heavy towing), a more robust seal (such as those from **DuraSeal, GMB, or OEM Jeep parts**) might offer better longevity.

2. **Potential for Early Wear in Harsh Environments**

In **extreme heat, cold, or abrasive conditions**, the rubber compound may degrade faster than expected. Some users report that in very dusty or off-road-heavy applications, the seal may wear out sooner than in on-road or mild off-road use.

3. **Requires Proper Installation Technique**

If the seal is **not installed correctly** (e.g., improper lubrication, misalignment, or damage during removal), it can fail prematurely or leak. This is true of any pitman shaft seal, but improper installation is a common cause of early failure.

4. **Limited Warranty**

InMotion typically offers a **limited warranty** (often 1 year or 12 months), which may not cover all failure modes (e.g., improper installation or misuse). This means you bear the risk if the seal fails due to factors beyond the manufacturer s control.

5. **May Not Fit Aftermarket Steering Gear Upgrades**

If you have installed an **aftermarket steering gear** (e.g., from **Spicer, GMB, or other brands**), the InMotion WS313842 may **not be compatible**. Always verify fitment with your specific steering gear model, as aftermarket units often use different seal sizes or mounting configurations.

6. **Grease Compatibility Concerns**

The seal s performance depends on using the **correct grease** (typically **Lithium-based or high-temperature grease**). If the wrong grease is used, it can cause the seal to dry out or degrade prematurely. Some users report issues if they use **cheap or incorrect grease**, leading to leaks.

7. **No Additional Features (e.g., Reinforced or Self-Lubricating)**

Unlike some higher-end seals, the InMotion WS313842 does **not include additional features** such as **reinforced edges, self-lubricating properties, or metal reinforcement**. For users who prioritize extreme durability, these features may be desirable.

---

### **Conclusion**

The **InMotion WS313842 pitman shaft seal** is a **solid, cost-effective choice** for most TJ Wrangler owners who need a **direct OEM replacement** for their steering gear. It offers **reliable leak prevention**, ease of installation, and good availability, making it a practical option for everyday driving and light off-roading. However, it is **not the best choice** for users pushing their vehicles to the limits in extreme off-road conditions or those who have modified their steering systems significantly.

If your primary concern is **preventing leaks and maintaining steering integrity** without breaking the bank, this seal is a **good recommendation**. However, if you operate your TJ in **harsh, high-stress environments** or have aftermarket steering components, you may want to consider a **higher-end seal** (e.g., **GMB, DuraSeal, or OEM Jeep part**) for added durability.

---

### **Final Recommendation**

- You need a **direct OEM replacement** for your stock TJ Wrangler steering gear.

- You prioritize **affordability, ease of installation, and reliable leak prevention** for normal driving or light off-roading.

- You are comfortable with **basic DIY maintenance** and proper greasing techniques.

- You do **not** have aftermarket steering gear or extreme modifications.

- You operate your TJ in **extreme off-road conditions** (rock crawling, heavy towing, etc.).

- You have **aftermarket steering gear** that may require a different seal.

- You want **longer-lasting performance** and are willing to pay a premium for it.

- You frequently encounter **abrasive or corrosive environments** (e.g., salt, sand, extreme temperatures).

For most **stock or lightly modified TJ Wranglers**, the InMotion WS313842 is a **reliable and cost-effective solution**. Always ensure proper installation and use the **correct grease** to maximize its lifespan.
