### Pros and Cons of buying a Apex Auto ABS1303 Rear Crankshaft Seal Kit for a 1969-1972 Ford F-250

The Apex Auto ABS1303 rear crankshaft seal kit is a popular choice for restoring or maintaining the rear main seal on older Ford F-250 trucks from the late 1960s. Here are the key advantages:

1. **Compatibility** This kit is specifically designed for the 1969-1972 Ford F-250 models, ensuring a proper fit without modifications. It includes all necessary components, such as the seal itself, gasket, and sometimes a new rear main bearing cap or related hardware, depending on the kit s contents.

2. **Quality Materials** Apex Auto is known for using durable materials that can withstand the demands of heavy-duty applications. The seal is typically made from high-quality rubber or synthetic compounds that resist oil degradation and heat better than OEM parts.

3. **Ease of Installation** The kit is designed to simplify the replacement process. It often includes clear instructions, and the components are pre-packaged for straightforward assembly. This can save time and reduce the risk of errors during installation.

4. **Prevents Leaks** A failing rear crankshaft seal is a common source of oil leaks in older trucks. Replacing it with this kit can eliminate persistent oil leaks from the rear main housing, preventing further engine damage and keeping the vehicle running smoothly.

5. **Cost-Effective Solution** While not the cheapest option, it is often more affordable than a full engine rebuild or replacement. It extends the life of the engine by addressing a critical wear point.

6. **Aftermarket Support** Apex Auto is a well-established brand with a reputation for reliability. If issues arise, there is often customer support available for guidance or replacements.

---

1. **Installation Complexity** Replacing a rear crankshaft seal is a labor-intensive job that requires disassembling the engine s lower end, including the transmission or differential. This is not a beginner-friendly repair and may require mechanical expertise or professional assistance.

2. **Potential for Additional Wear** If the seal failure was due to prolonged neglect (e.g., lack of oil changes, excessive heat, or contamination), simply replacing the seal may not fully resolve underlying issues. The crankshaft or bearing surfaces might also be worn, requiring additional repairs.

3. **Cost of Labor** Even if the kit itself is reasonably priced, the labor costs for a professional mechanic to perform the job can be high. For DIYers, the time and effort required may outweigh the savings.

4. **Limited Longevity Guarantee** Unlike some modern OEM parts, aftermarket seals like this one may not come with a long warranty. If the seal fails prematurely, the owner may be responsible for replacement costs again.

5. **Risk of Improper Installation** If not installed correctly, the new seal could leak or fail prematurely. Improper torque on the bearing cap or misalignment can cause damage to the crankshaft or seal.

6. **Availability of Parts** While Apex Auto is reliable, there is always a risk of stock shortages or delays in shipping, especially for older or less common models. Ensuring the kit is in stock before purchasing is advisable.

The Apex Auto ABS1303 rear crankshaft seal kit is a solid choice for restoring the rear main seal on a 1969-1972 Ford F-250. It offers a balance of quality, compatibility, and ease of use, making it a practical solution for preventing oil leaks and extending engine life. However, the repair itself is technically demanding and may require professional help or significant mechanical skill.

If your truck is experiencing rear main seal leaks and you are confident in your ability to perform the repair or are willing to pay for professional labor the kit is a worthwhile investment. On the other hand, if the engine has other underlying issues (e.g., worn bearings, cracked blocks, or excessive crankshaft wear), addressing those problems concurrently may be necessary to ensure long-term reliability.

---

1. **Verify the Need for Replacement** Confirm that the leak is indeed coming from the rear main seal (not the transmission or differential) by inspecting the area carefully. A visual inspection or a leak-down test may help diagnose the issue.

2. **Assess Your Mechanical Skill Level** If you lack experience with engine disassembly or crankshaft seal replacement, consider hiring a professional mechanic. Improper installation can lead to further damage.

3. **Check for Additional Repairs** If the engine has been running with a leaking seal for an extended period, inspect the crankshaft and bearing surfaces for wear. Replacing just the seal may not be sufficient if other components are damaged.

4. **Purchase from a Reputable Source** Buy the kit from a trusted supplier (e.g., RockAuto, Summit Racing, or a local auto parts store with good reviews) to ensure authenticity and quality.

5. **Budget for Labor** If you re not doing the work yourself, factor in the cost of professional labor. A reputable mechanic may charge $300 $600 or more for this repair, depending on location and shop rates.

6. **Consider Alternatives** If the engine is old or has other significant issues, weigh the cost of this repair against the potential value of the vehicle. In some cases, a rebuild or replacement engine may be more cost-effective in the long run.

**Final Verdict:** The Apex Auto ABS1303 kit is a reliable and compatible option for fixing a rear crankshaft seal leak in your 1969-1972 Ford F-250. Proceed with the purchase if you are prepared for the repair s complexity and potential costs, and ensure the work is done correctly to avoid future issues.
