Here's a general outline of the process. Specifics may vary slightly depending on your exact model and the condition of your vehicle. Always consult a repair manual specific to your 1990 Plymouth Voyager for precise instructions and torque specifications. A Haynes or Chilton manual is a good investment.
Tools You'll Likely Need:
* Jack and jack stands: Essential for safety. Never work under a vehicle supported only by a jack.
* Wheel chocks: To prevent the vehicle from rolling.
* Lug wrench: To remove the wheel.
* Tie rod removal tool: This specialized tool is crucial for removing the tie rod end from the steering knuckle. Trying to do it without one risks damaging the knuckle or the tie rod end.
* Wrench(es) to fit the tie rod end: Probably a combination wrench or a socket.
* Wrench to fit the tie rod adjusting sleeve: Usually a large open-end wrench or a box wrench.
* Socket wrench set: For various fasteners.
* Penetrating oil (PB Blaster, etc.): Helps loosen rusted or seized fasteners.
* Torque wrench: Absolutely necessary to tighten the components to the manufacturer's specifications. Incorrect torque can lead to premature wear or failure.
* Wheel alignment tool: After replacement, you'll *need* a wheel alignment. Don't drive it without one.
Procedure (General Steps):
1. Safety First: Engage the parking brake firmly. Chock the wheels. Raise the vehicle using the jack and secure it on jack stands. Remove the wheel.
2. Locate the Tie Rod: Identify the tie rod end connected to the steering knuckle (the part of the suspension that holds the wheel). It's usually a metal rod with a ball joint at the end.
3. Disconnect the Tie Rod End: Apply penetrating oil to the threads where the tie rod connects to the knuckle. Use the tie rod removal tool to separate the tie rod end from the steering knuckle. This is where the specialized tool is essential.
4. Remove the Tie Rod: Disconnect the tie rod from the steering rack. This usually involves loosening a nut or jam nut on the adjusting sleeve. Note the position of the adjusting sleeve relative to the tie rod threads - this is crucial for reinstalling it correctly. Keep track of how many threads were showing and their orientation. You'll need this information for reinstallation, because this will maintain correct toe alignment *temporarily*.
5. Install the New Tie Rod: Thread the new tie rod onto the steering rack, ensuring it's the correct length according to your earlier measurements. Tighten the jam nut/sleeve, leaving enough thread length for adjustments.
6. Reconnect the Tie Rod End: Install the new tie rod end onto the steering knuckle using the tie rod removal tool.
7. Lower the Vehicle: Carefully lower the vehicle using the jack.
8. Torque Specifications: Tighten all nuts and bolts to the manufacturer's specified torque settings as found in your repair manual. This is critical for safety and component longevity.
9. Wheel Alignment: Do not drive the vehicle until a professional wheel alignment has been performed. Even a slight misalignment can cause premature tire wear and unsafe handling.
Important Considerations:
* Left vs. Right: Tie rods are generally not interchangeable between the left and right sides. Make sure you get the correct part for the side you're replacing.
* Thread Direction: Note the direction of the threads on the tie rod and adjusting sleeve. Incorrect threading can lead to damage.
* Steering Rack: This repair may require careful observation of the steering rack position to ensure proper alignment.
This is a simplified overview. Refer to a repair manual specific to your 1990 Plymouth Voyager for detailed instructions and torque specifications. If you are not comfortable with this repair, seek professional assistance from a qualified mechanic. Incorrect installation can lead to dangerous driving conditions.
