Here's a general overview. Specific steps and tools may vary slightly depending on your Explorer's trim level and whether you have 4WD or 2WD. Always consult a repair manual specific to your vehicle year and model for detailed instructions and torque specifications.
Tools You'll Likely Need:
* Jack and jack stands (SAFETY FIRST: Secure the vehicle properly before working under it)
* Wrench set (metric)
* Socket set (metric)
* Ratchet
* Torque wrench
* Penetrating oil (like PB Blaster)
* Shock compressor (highly recommended, especially for the top nut)
* Wheel chocks
* Safety glasses
* Gloves
Steps (General Outline):
1. Preparation: Park on a level surface, engage the parking brake, and chock the rear wheels. Locate your new shocks. Make sure they are the correct ones for your vehicle.
2. Wheel Removal: Remove the wheel from the affected side.
3. Shock Removal:
* Top Nut: This is often the most difficult part. You'll need to use a shock compressor to compress the shock and relieve the pressure on the top nut. This prevents the shock from shooting up and potentially injuring you. Locate the top nut and carefully loosen it using the appropriate socket and wrench. *Be cautious, as this area can be rusty or seized.*
* Bottom Nut/Bolt: Locate the bottom nut or bolt attaching the shock to the lower control arm or knuckle. Use penetrating oil if necessary and loosen it with the appropriate wrench.
* Remove the Shock: Once both the top and bottom are loose, carefully remove the old shock.
4. Installation of New Shock:
* Compressor (again): Use the shock compressor to partially compress the new shock. This makes installation much easier.
* Alignment: Carefully align the new shock with the mounting points on the control arm/knuckle and the frame/strut tower.
* Attachment: Install the bottom nut/bolt first, then carefully install the top nut/bolt while still using the compressor.
* Tightening: Tighten both the top and bottom fasteners to the manufacturer's specified torque. Do not overtighten. Release the shock compressor.
5. Reassembly: Replace the wheel. Repeat steps 3 and 4 for the other side if needed.
6. Test: Lower the vehicle, and carefully check for proper shock movement and secure fastening. Test drive to check for any unusual noises or handling issues.
Important Considerations:
* Rust: Older Explorers are prone to rust, especially in the suspension components. Penetrating oil will be your friend. You may need to use heat (carefully!) to loosen stubborn bolts.
* Safety: Always work on a level, stable surface. Never work under a vehicle supported only by a jack. Use jack stands for safety.
* Torque Specifications: Refer to your repair manual for the correct torque specifications for all fasteners. Using a torque wrench is crucial to avoid over-tightening and damaging components.
* Alignment: After replacing shocks, it's a good idea to have your front end alignment checked by a professional to ensure optimal handling and tire wear.
This is a general guide. Consult a repair manual specific to your 1998 Ford Explorer for detailed instructions and diagrams. If you're unsure about any step, it's always best to seek professional help. Improperly installed shocks can lead to dangerous driving conditions.
