### **Pros and Cons of buying a 551-01535 Steering Gear/Rack Power Rack Pinion (Door 90 Le Baron)**

1. **Compatibility with Ford Models** This part is specifically designed for the **1981 1990 Ford Mustang (LX, GL, Ghia, and some SVO models)**, including the **Le Baron variant of the Ford Thunderbird (1981 1989)**. It ensures a proper fit without modifications, reducing the risk of alignment or handling issues.

2. **Reliability and Durability** Ford s steering racks from this era are known for being sturdy, especially when maintained properly. The **power rack-and-pinion system** provides smoother steering compared to recirculating ball systems, reducing wear over time.

3. **Ease of Installation** As an OEM (Original Equipment Manufacturer) part, it comes with all necessary hardware and mounting points, making installation straightforward for those with basic mechanical skills. Many aftermarket parts require additional modifications.

4. **Improved Steering Feel** The rack-and-pinion design offers **better responsiveness and precision** compared to older recirculating ball systems, which can feel sluggish or imprecise.

5. **Prevents Leaks and Wear** If your current steering rack is leaking power steering fluid or showing signs of internal wear (e.g., grinding noises, excessive play), replacing it with this OEM part ensures a **fresh, sealed unit** that should last for years with proper maintenance.

6. **Resale Value** Keeping the vehicle stock with OEM parts can **preserve its value**, especially if you plan to sell it in the future. Aftermarket parts may deter some buyers.

7. **Warranty Coverage** If purchased from an authorized dealer or a reputable supplier, this part may come with a **limited warranty**, providing peace of mind against defects.

1. **Cost** OEM steering racks can be **expensive**, often ranging between **$300 $600** depending on the source (dealer vs. online auction). This is significantly more than many aftermarket alternatives, which may offer similar performance at a lower price.

2. **Age-Related Wear** Even if this is an OEM part, **older stock units (especially from salvage yards)** may have been sitting unused for years and could develop **internal corrosion or dryness**. Inspecting the part before purchase is crucial.

3. **Limited Availability** Unlike newer Ford models, finding a **new OEM steering rack** for these older vehicles can be difficult. Many suppliers only carry **used or rebuilt units**, which may not be ideal if you want a fresh part.

4. **Potential for Counterfeit Parts** Some online sellers may offer **fake or rebranded parts** labeled as OEM. These can fail prematurely or not fit correctly. Always verify the seller s reputation and part authenticity.

5. **Installation Complexity** While not extremely difficult, replacing a steering rack requires **removing the steering column, tie rods, and sometimes the sway bar**, which can be time-consuming for inexperienced mechanics. If unsure, professional installation is recommended.

6. **Power Steering Fluid Compatibility** If your vehicle has been running on **old or contaminated fluid**, the new rack may require a **fluid flush** to prevent premature wear. Neglecting this step can void warranties or shorten the part s lifespan.

7. **Weight and Bulk** The rack-and-pinion system is **heavier than some aftermarket alternatives**, which might slightly affect **handling dynamics** in a modified or high-performance vehicle.
