Here's a general overview of the process. This is not a complete guide and should not be used as your sole source of information. Always consult a repair manual for your specific vehicle:
1. Preparation:
* Safety First: Disconnect the negative battery terminal. Use jack stands to safely support the vehicle.
* Gather Tools and Parts: You'll need a variety of tools, including socket wrenches, combination wrenches, screwdrivers (Phillips and flathead), pliers, a power steering fluid catch pan, new seals (ensure you get the correct ones for your specific model), possibly a seal installer tool, and fresh power steering fluid. You might also need a torque wrench.
* Fluid Drainage: Locate the power steering fluid reservoir and drain the fluid into a suitable container.
2. Accessing the Seals:
* Identify the Leaking Seal: Pinpoint the location of the leak. Common areas are the power steering pump seals, rack and pinion seals, or high-pressure hose seals.
* Component Removal: This is where the complexity varies greatly depending on which seal needs replacing. You may need to remove:
* Power Steering Pump: This often involves removing belts, hoses, and possibly brackets.
* Rack and Pinion: This is a significantly more involved process that often requires special tools and expertise.
* High-Pressure Hose: This involves disconnecting the hose carefully and might require special hose clamps.
3. Seal Replacement:
* Old Seal Removal: Carefully remove the old seal(s) using appropriate tools. Avoid damaging the surrounding components.
* Seal Installation: Install the new seal(s) using the correct technique. A seal installer tool is highly recommended to prevent damage. Lubricate the new seals with power steering fluid.
* Reassembly: Reinstall the removed components in the reverse order of removal. Pay close attention to the correct orientation of parts and torque specifications (refer to your repair manual).
4. Refill and Bleeding:
* Refill: Refill the power steering fluid reservoir with the correct type and amount of fluid.
* Bleeding: Bleed the power steering system according to your repair manual. This is crucial to remove air bubbles from the system. This may involve turning the steering wheel lock-to-lock several times with the engine running.
5. Testing:
* Check for Leaks: After refilling and bleeding, carefully inspect for leaks. Run the engine and turn the steering wheel lock-to-lock. Check all connections and seals for leaks.
Important Considerations:
* Repair Manual: A repair manual is absolutely essential for this repair. It will provide detailed instructions, torque specifications, and diagrams specific to your vehicle.
* Professional Help: If you're not comfortable performing this repair yourself, it's best to take your Jeep to a qualified mechanic. Incorrect installation can lead to significant damage and expensive repairs.
* Safety: Always prioritize safety. Use jack stands, wear safety glasses, and work in a well-ventilated area.
This is a simplified overview. The actual procedure is much more involved and requires detailed, step-by-step instructions found in a repair manual specific to your 1998 Jeep Wrangler. Attempting this repair without the proper knowledge and tools can cause significant damage. If you're unsure, seek professional help.
