The **551-58233 Steering Gear/Rack Manual Rack and Pinion Assembly (Model Years 1987 1990 Tercel)** is a precision-engineered component designed to deliver smooth, responsive, and reliable steering performance in the iconic Mitsubishi Tercel, a compact hatchback known for its practicality and nimble handling. This manual rack and pinion assembly represents a critical upgrade or replacement part for vehicles equipped with the original power-assisted or manual steering systems, ensuring optimal alignment, reduced play, and enhanced driver control. Crafted from high-grade materials, including durable steel for the rack and precision-machined pinion gear, this assembly is engineered to withstand the demands of daily driving while maintaining a tight, linear motion that translates driver input into precise wheel movement. The rack itself features a robust, sealed design with corrosion-resistant coatings to protect against rust and wear, particularly important for vehicles operating in varied climates or exposed to road salt and moisture. The pinion gear, meshing seamlessly with the rack s teeth, is designed for minimal friction and extended longevity, reducing the risk of binding or premature failure. This assembly is compatible with the Tercel s front-wheel-drive architecture, integrating directly into the steering column linkage and tie rods, ensuring compatibility with the vehicle s suspension geometry and steering ratio. Whether replacing a worn-out original component or upgrading to a more durable aftermarket solution, this rack and pinion assembly offers a balance of performance and reliability, allowing the Tercel to maintain its reputation for agile handling and driver engagement. Its straightforward installation typically requiring only basic tools and minimal disassembly makes it an accessible yet high-quality choice for both DIY enthusiasts and professional mechanics. With proper maintenance, including regular inspection of tie rod ends, steering fluid levels (if applicable), and rack bushings, this assembly can significantly extend the lifespan of the steering system, ensuring the Tercel remains a joy to drive for years to come.
### **Pros and Cons of Buying a Used 551-58233 Steering Gear (Manual Rack & Pinion, 1987-1990 Tercel)**
#### **Pros:**1. **Compatibility and Fitment** This steering gear is designed specifically for the **1987-1990 Mitsubishi Tercel**, ensuring a direct replacement with no modifications required. It is a common part for this model, making sourcing easier than aftermarket alternatives.
2. **Reliability of Rack & Pinion Systems** Rack and pinion steering is generally more durable and precise than recirculating ball or worm gear systems, offering smoother operation and better responsiveness. If well-maintained, it can last for decades.
3. **Ease of Installation** Since it is an OEM (Original Equipment Manufacturer) part, installation typically requires only basic tools and does not involve complex modifications. Many mechanics are familiar with this setup.
4. **Better Steering Feel** Compared to older hydraulic or power-assisted systems, a manual rack and pinion provides a more direct and engaging steering experience, which some drivers prefer.
5. **Availability of Replacement Parts** If issues arise (e.g., leaks, worn seals), replacement components like boots, tie rods, or bushings are widely available for this model.
6. **Cost-Effective for the Model** While not brand new, this part is often cheaper than aftermarket alternatives that may not match the original specifications perfectly.
7. **Proven Performance** Mitsubishi s rack and pinion systems from this era were designed for durability, and many still function reliably in older vehicles with proper maintenance.

#### **Cons:** 1. **Age and Wear** Being from the late 1980s, the part may show signs of wear, such as:- **Leaking seals or boots** (common in older rack and pinion systems).
- **Stiffness or play** due to worn bushings or tie rods.
- **Rust or corrosion** if the vehicle was exposed to harsh conditions.
You will need to inspect it thoroughly before purchasing.
2. **Potential Hidden Damage** Without a full inspection, internal damage (e.g., bent rack, worn pinion gears) may not be immediately visible. This could lead to premature failure or costly repairs.
3. **Maintenance Requirements** Rack and pinion systems require periodic checks for:- **Boot integrity** (prevents dirt and moisture from entering).
- **Tie rod condition** (worn threads or bushings can cause misalignment).
- **Ball joint and control arm wear** (affects steering precision).
Neglecting these can lead to accelerated wear.
4. **Limited Warranty (If Applicable)** Used parts typically come with no warranty, so you bear full responsibility for any defects. Some sellers may offer a short return window, but this is rare.
5. **Compatibility with Modern Vehicles** While this part fits the Tercel, if you plan to modify the vehicle (e.g., lowering, wider tires), the stock rack may not accommodate these changes without adjustments.
6. **Potential for Counterfeit Parts** If purchasing from an unverified source, there is a risk of receiving a **rebuilt or aftermarket knockoff** that does not meet OEM standards. Always verify the part s authenticity.
7. **Labor Costs** If installation is not done correctly, improper alignment or torque can lead to premature wear or safety issues. Some mechanics may charge extra for proper installation.

### **Conclusion:** Buying a **used 551-58233 steering rack (1987-1990 Tercel)** can be a **cost-effective and reliable solution** if you:- **Inspect it thoroughly** for leaks, stiffness, or damage.
- **Verify its origin** (preferably from a trusted seller with a return policy).
- **Budget for potential maintenance** (seals, tie rods, or bushings).
- **Plan to replace it if it shows significant wear** rather than risking failure.
However, if the part is **in poor condition** (e.g., leaking, bent, or seized), it may be **more economical to purchase a new or remanufactured OEM replacement** or a **high-quality aftermarket alternative** (e.g., from **Dorman, Febi Bilstein, or ACDelco**) to avoid future issues.
---
### **Recommendation:** 1. **If the part is in good condition (no leaks, smooth operation, intact boots):**- **Proceed with purchase** from a **reputable seller** (eBay, RockAuto, or a trusted mechanic).
- **Inspect tie rods, ball joints, and control arms** replace any worn components simultaneously.
- **Consider a short test drive** (if possible) to check for stiffness or unusual noises.
2. **If the part shows signs of wear (leaks, roughness, bent rack):**- **Avoid purchasing** unless you are prepared to **replace it entirely** with a new or remanufactured unit.
- **Compare prices** sometimes a **new OEM rack** (e.g., from **Mitsubishi or a remanufacturer**) is only slightly more expensive than a used one but comes with guarantees.
3. **If you are unsure about inspection:**- **Hire a mechanic** to evaluate the part before buying.
- **Consider an aftermarket rack** (e.g., **Dorman 09400**) if you want a **warranty-backed** alternative.
4. **For long-term reliability:**- **Prioritize a remanufactured OEM rack** if budget allows, as it will have **new seals, bearings, and proper lubrication**.
- **Budget for periodic maintenance** (every 50,000 70,000 miles) to check boots, tie rods, and bushings.
### **Final Verdict:**A **used 551-58233 steering rack can be a good deal** if you **verify its condition carefully** and are prepared for potential maintenance. However, if the part is **compromised**, investing in a **new or remanufactured unit** may save money in the long run by avoiding premature failure. Always **balance cost with risk** if the part is **near the end of its lifespan**, it may not be worth the gamble.
