The Jeep XJ Cherokee, a beloved off-road vehicle, has a known weakness: its factory steering geometry. This often results in bump steer and imprecise handling, particularly on challenging terrain. A steering box spacer can significantly alleviate these issues, offering improved steering feel and response. This guide delves into the benefits, installation, and considerations for using a steering box spacer on your XJ.
Understanding the Need for a Steering Box Spacer
The XJ's steering linkage is inherently susceptible to bump steer – a condition where suspension articulation affects steering alignment, causing the wheels to turn unexpectedly. This is exacerbated by the high caster angle often found in lifted XJs. A steering box spacer addresses this by changing the angle of the drag link, effectively reducing bump steer and improving steering responsiveness.
Key Benefits of a Steering Box Spacer:
- Reduced Bump Steer: This is the primary benefit. A properly installed spacer minimizes unwanted steering inputs caused by suspension movement, leading to smoother, more predictable handling.
- Improved Steering Feel: Many XJ owners report a more direct and precise steering feel after installing a spacer. This is particularly noticeable at higher speeds and on uneven terrain.
- Enhanced Off-Road Performance: Better steering control translates to improved maneuverability on challenging trails. You'll experience less unwanted steering corrections, allowing for more confident driving.
- Increased Caster Angle (In Some Cases): While not always the case, a spacer can sometimes slightly increase caster, further enhancing steering stability.
Types of Steering Box Spacers
Several types of steering box spacers are available, differing primarily in material and design:
- Aluminum Spacers: These are popular due to their lightweight yet robust nature. They offer a good balance of strength and weight savings.
- Steel Spacers: Steel spacers are heavier but offer superior strength and durability. This is a preferred choice for heavily modified XJs or those used for extreme off-roading.
Regardless of material, ensure the spacer is specifically designed for the Jeep XJ Cherokee. Incorrect sizing or improper installation can lead to steering issues and potential safety hazards.
Installation Considerations and Process
Installing a steering box spacer is generally straightforward but requires some mechanical aptitude and the right tools. It's crucial to consult a detailed installation guide specific to your chosen spacer. However, some general steps include:
- Disconnecting the Steering Linkage: Safely disconnect the drag link from the steering arm and the tie rod from the steering knuckle.
- Removing the Steering Box Mount Bolts: Carefully remove the bolts securing the steering box to the frame.
- Installing the Spacer: Position the spacer between the steering box and its mounting bracket.
- Re-attaching the Steering Box: Securely tighten the steering box mount bolts.
- Re-connecting the Steering Linkage: Re-attach the drag link and tie rod, ensuring proper alignment.
- Toe-in Adjustment: After installation, it is crucial to have a professional alignment done to adjust the toe-in.
Important Note: Improper installation can seriously compromise your vehicle's safety. If you lack experience working on your vehicle's steering system, consult a qualified mechanic.
Conclusion: A Worthwhile Upgrade for Enhanced Control
A steering box spacer can be a valuable upgrade for your Jeep XJ Cherokee, significantly improving steering feel and off-road performance. By reducing bump steer and enhancing control, it contributes to a safer and more enjoyable driving experience. However, remember to choose a high-quality spacer and ensure proper installation to maximize the benefits and avoid potential problems. Always prioritize safety and, when in doubt, seek professional assistance.
