However, if you're determined to tackle this yourself, here's a general overview of the process. This is not a comprehensive guide and may not cover all variations or potential issues. Consult a repair manual specific to your 1995 Oldsmobile Achieva for detailed instructions, torque specifications, and safety precautions.
Tools and Materials You'll Need (at a minimum):
* Repair Manual: Absolutely essential for specific details to your vehicle.
* Jack and Jack Stands: Securely support the vehicle.
* Wheel Chocks: For safety.
* Wrench Set: Various sizes, including metric.
* Socket Set: Various sizes, including metric.
* Ratcheting Wrenches: Speed up the process.
* Tie Rod Separator: To remove tie rod ends.
* Rack and Pinion Puller: May be necessary to remove the rack.
* New Rack and Pinion Assembly: Ensure you get the correct part number for your vehicle.
* New Tie Rod Ends: Usually replaced during rack and pinion replacement.
* New Power Steering Fluid: The correct type for your vehicle.
* New Rack Boots: These protect the rack from dirt and debris.
* Torque Wrench: Essential for proper tightening of bolts.
* Drain Pan: To catch power steering fluid.
* Penetrating Oil (PB Blaster, etc.): To loosen rusted bolts.
* Gloves and Safety Glasses: Always wear safety gear.
General Steps (Again, refer to your repair manual for specifics):
1. Disconnect the Battery: This is crucial to prevent electrical shorts.
2. Raise and Secure the Vehicle: Use jack stands to securely lift and support the vehicle.
3. Drain the Power Steering Fluid: Locate the power steering fluid reservoir and drain the fluid into a suitable container.
4. Disconnect the Tie Rod Ends: Use a tie rod separator to carefully separate the tie rod ends from the steering knuckles. Mark the position of the tie rods relative to the rack before disconnecting; this is critical for proper alignment later.
5. Disconnect Power Steering Lines: Carefully disconnect the high-pressure and low-pressure power steering lines from the rack and pinion. Be prepared for some fluid spillage. Plug the lines to prevent fluid loss.
6. Disconnect the Steering Shaft: Disconnect the steering shaft from the rack and pinion.
7. Remove the Rack and Pinion: This step often requires a rack and pinion puller and may involve removing other components depending on your vehicle's design. Consult your repair manual for specific instructions.
8. Install the New Rack and Pinion: Install the new rack and pinion, ensuring proper alignment and seating.
9. Reconnect Everything: Reconnect the steering shaft, power steering lines, tie rod ends (using your markings as a guide), and other components in the reverse order of removal.
10. Bleed the Power Steering System: Carefully bleed the air from the power steering system to remove any trapped air bubbles.
11. Lower the Vehicle: Lower the vehicle from the jack stands.
12. Fill with Power Steering Fluid: Fill the power steering fluid reservoir with the correct type of fluid to the recommended level.
13. Check for Leaks: Carefully inspect all connections for leaks.
14. Have an Alignment Done: A wheel alignment is absolutely necessary after replacing the rack and pinion to ensure proper handling and tire wear.
Warnings:
* Power steering fluid is under pressure. Release pressure before disconnecting lines.
* Incorrect tightening torques can damage components. Use a torque wrench and consult your repair manual.
* Working under a vehicle is dangerous. Always use jack stands and follow safety procedures.
* Improper installation can lead to serious driving problems and accidents.
This is a simplified overview. The actual process is significantly more complex and potentially dangerous. If you lack the experience or proper tools, hire a professional mechanic. The cost of repair versus the potential for injury and vehicle damage makes professional service a much safer and often more economical option in the long run.
