Tools You'll Likely Need:
* Jack and jack stands: Essential for safety. Never work under a vehicle supported only by a jack.
* Lug wrench: To remove the wheels.
* Socket wrench set: You'll need sockets of various sizes, likely including a 15mm or 18mm (check your repair manual).
* Wrench: Possibly a combination wrench or open-end wrench to help break loose stubborn bolts.
* Penetrating oil (like PB Blaster): Spray this on the bolts several hours or overnight before attempting removal to loosen rust and corrosion.
* Ratchet: Makes the job much easier.
* Torque wrench: Crucial for tightening the new bolts to the correct specification. Over-tightening can strip the threads.
* New lower shock bolts: Get the correct grade and size from a parts store; providing your VIN will ensure you get the correct parts.
* Safety Glasses and Gloves: Protect yourself!
Procedure (General Steps - Consult Your Repair Manual for Precise Details):
1. Safety First: Park on a level surface, engage the parking brake, and chock the wheels. Raise the van securely using the jack and place it on jack stands under the frame near the shock absorber you're working on. Remember, safety is paramount.
2. Remove the Wheel: Remove the lug nuts and take off the wheel.
3. Access the Lower Shock Bolt: You'll need to locate the lower shock mount. This is usually bolted to the axle or the control arm. The bolt(s) will connect the shock absorber to this mount.
4. Apply Penetrating Oil: Generously spray penetrating oil onto the bolt(s). Let it soak for as long as possible (ideally overnight).
5. Remove the Lower Shock Bolt(s): Use the appropriate socket and ratchet to carefully remove the bolt(s). They may be quite stubborn due to rust and corrosion. A breaker bar might be necessary. If the bolt head starts to round off, try using a different socket or a wrench to grip it.
6. Install the New Bolt(s): Clean the bolt holes thoroughly. Install the new bolts, making sure they are correctly aligned.
7. Tighten the Bolt(s): This is crucial. Use your torque wrench and tighten the bolts to the manufacturer's specified torque. You'll find this specification in your repair manual. Over-tightening can damage threads and components.
8. Reassemble: Reinstall the wheel, making sure the lug nuts are tightened properly. Lower the van carefully.
9. Repeat: Repeat the process for the other side if necessary.
Important Considerations:
* Suspension Component Wear: While you're working on the shocks, inspect the other suspension components (bushings, ball joints, etc.) for wear and tear. Replacing worn parts now can prevent future problems.
* Repair Manual: This is not a substitute for a repair manual specific to your 1999 Ford E150. Always consult your manual for detailed diagrams, torque specifications, and specific instructions.
* Professional Help: If you're not comfortable performing this repair yourself, take your van to a qualified mechanic. Improper repair can compromise your safety and vehicle handling.
Remember, safety is the utmost priority. If you're unsure about any step, seek professional assistance.
