Installation (Setup)
This section outlines the general steps for installing the Rugged Ridge Steering Box Brace. Specific vehicle configurations may vary, and professional installation is recommended if you are unsure about any steps.
Tools Required:
- Standard wrench set
- Socket set
- Torque wrench
- Jack and jack stands
- Safety glasses and gloves
- WD-40 or similar lubricant (optional, for stubborn bolts)
Installation Steps:
- Park the vehicle on a flat, stable surface and engage the parking brake.
- Safely lift the front of the vehicle using a jack and support it securely with jack stands.
- Locate the steering box on the driver's side frame rail.
- Identify the mounting points for the steering box brace. One end of the brace will attach to the frame, often utilizing an existing shackle hanger bolt, and the other end will clamp around the steering gearbox.
- Loosely install the frame-side bolt(s) for the brace. Some users report needing a coarse-thread 7/16" x 14 bolt for the rear hole on the passenger side, as the supplied bolt may be fine-thread.
- Position the clamp end of the brace around the steering gearbox.
- Install the bolts, washers, and nuts for the clamp end, ensuring a snug fit around the gearbox.
- Once all bolts are in place, progressively tighten all fasteners to the manufacturer's recommended torque specifications. Ensure the brace is securely holding the steering box without causing undue stress or misalignment.
- Lower the vehicle safely.
- Test the steering for proper operation and ensure no new noises or vibrations are present.
Note: Some installations may require minor adjustments or modifications due to vehicle age or previous modifications.
Operation
The Rugged Ridge Steering Box Brace is a passive component designed to reinforce the steering box mounting. Once properly installed, it operates continuously to reduce flex and movement of the steering box, contributing to improved steering feel and reduced "steering wander" or "death wobble" common in older Jeep CJ models.
No active user operation is required after installation. The brace works in conjunction with your existing power steering system to provide a more stable and responsive steering experience.
Maintenance
Regular inspection of the steering box brace is recommended to ensure continued performance and safety.
Maintenance Schedule:
- Every 3 months or 3,000 miles (whichever comes first):
- Visually inspect the brace for any signs of damage, cracks, or corrosion.
- Check all mounting bolts for tightness. Re-torque if necessary according to the vehicle's service manual or general automotive torque specifications for the bolt size.
- Ensure the brace is not interfering with any other vehicle components.
- After any off-road excursion:
- Perform a quick visual inspection for impacts or damage from debris.
Clean the brace periodically with mild soap and water to remove dirt and grime, especially if exposed to harsh conditions like road salt or mud. The black powder-coated finish is designed for durability but can be compromised by severe impacts or prolonged exposure to corrosive elements without cleaning.
