Review JAGUAR 87-91 Xjs Series Power Steering Rack And Pinion Oem 64k

The **Jaguar CBC5709 Power Steering Rack and Pinion Assembly (1987 1991 XJS Models)** is a meticulously engineered, high-performance component designed to deliver precise, responsive steering control in Jaguar s iconic XJ-S sports sedans from the late 1980s. This direct-replacement unit is engineered to restore the original handling dynamics of the XJS, ensuring smooth, low-effort steering with minimal play while maintaining the vehicle s legendary road-hugging capability. Crafted from durable, corrosion-resistant materials, the rack and pinion assembly features a robust internal design with a recirculating ball mechanism, which enhances durability and reduces wear over time compared to older hydraulic systems. The pinion shaft is precision-machined to exacting tolerances, ensuring optimal alignment with the steering column and tie rods, while the rack itself is designed to accommodate the XJS s wide track and aggressive steering geometry, providing both comfort and sporty feedback. This aftermarket unit is built to meet or exceed OEM specifications, incorporating modern manufacturing techniques to eliminate common issues such as leaks, excessive noise, or premature failure, which were occasionally encountered in the original equipment. Whether restoring a classic XJS to its original glory or upgrading an existing system for improved reliability, this power steering rack and pinion assembly offers a seamless fit, enhanced longevity, and the confidence of a component that balances performance with practicality. Ideal for enthusiasts seeking a direct upgrade or those performing a full suspension or steering refresh, this part is a critical investment for maintaining the XJS s reputation as a driver s car.

### **Pros and Cons of Buying a Jaguar CBC5709 (1987 1991 XJS) Power Steering Rack Pinion**

1. **Common and Widely Available** The CBC5709 rack is one of the most common power steering racks for the XJS (XJ6) series, meaning parts, rebuild kits, and labor are relatively easy to find. This reduces the risk of long wait times or difficulty sourcing replacements.

2. **Repairable and Rebuildable** Unlike some modern systems, this rack can be disassembled, cleaned, and rebuilt with a kit (seals, bushings, bearings, etc.). A professional mechanic or even a skilled DIYer can restore it to near-new condition, saving significant money compared to buying a new rack.

3. **Lower Cost Compared to OEM Replacement** A new OEM or high-quality aftermarket rack can cost **$800 $1,500 **, depending on the source. A rebuilt or used rack (if in good condition) can be found for **$300 $700**, making it a cost-effective solution for budget-conscious owners.

4. **Compatibility with Modifications** The XJS is a popular car for tuning, and many aftermarket steering systems (e.g., rack-and-pinion upgrades, track steering) are designed to work with this rack s mounting points. Upgrading the rack later is feasible without major modifications.

5. **Good for Learning Mechanics** If you re interested in hands-on automotive work, rebuilding this rack is a manageable project that teaches you about hydraulic systems, seals, and alignment. Many Jaguar owners enjoy the satisfaction of restoring their own parts.

6. **Long-Term Reliability (When Maintained)** With proper maintenance (regular fluid changes, avoiding dry operation), this rack can last **100,000 miles**. Many XJS owners report rack failures only after neglect or extreme wear, not as a design flaw.

7. **Aftermarket Support** Brands like **Moog, Febi Bilstein, and local Jaguar specialists** produce rebuild kits and seals specifically for this rack. Online forums (e.g., Jaguar World, XJ6.net) provide step-by-step guides and troubleshooting tips.

1. **Potential for Leaks** Over time, the rack s seals and hoses can degrade, leading to **power steering fluid leaks**. If ignored, this can cause **whining noises, stiff steering, or complete loss of power assist**. Regular inspections are necessary.

2. **Whining Noise (Common Complaint)** Many owners report a **whining or groaning noise** from the rack, especially when turning or at low speeds. This is often due to **low fluid levels, air in the system, or worn internal components**. While not always critical, it can be annoying.

3. **Difficulty in Complete Replacement (DIY)** While rebuilding is manageable, **full rack replacement** (especially if the mounting points are corroded) can be tricky for beginners. It requires **removing the steering column, wheel bearings, and subframe**, which may necessitate specialized tools or a lift.

4. **Limited Lifespan if Neglected** If the rack runs **dry or without fluid changes**, the internal components (bearings, bushings) will wear out quickly, leading to **seized steering or complete failure**. Unlike modern systems, there s no "self-adjusting" mechanism proper maintenance is critical.

5. **Compatibility Issues with Later XJS Models** The **CBC5709** is specific to the **1987 1991 XJS (pre-facelift)**. If you plan to modify your car further (e.g., adding a later-model rack for better performance), you may need to **adjust mounting points or steering geometry**, which adds complexity.

6. **Cost of Professional Rebuild vs. Replacement** While DIY rebuilds save money, **professional labor** for a full rack rebuild can still cost **$300 $600**, depending on the shop. If the rack is beyond repair, a **new rack may be the better long-term investment**.

7. **Risk of Counterfeit or Low-Quality Parts** Some aftermarket rebuild kits or racks may be **cheaply made**, leading to premature failure. Buying from **reputable suppliers** (e.g., Jaguar specialists, known eBay sellers with good reviews) is essential to avoid this issue.
