However, if you're determined to do it yourself, here's a general outline of the steps involved. This is not a comprehensive guide and may miss specific details for your vehicle. You must consult a repair manual specific to your 1995 Chevrolet Lumina APV to get precise instructions and torque specifications. Improperly performing this repair can be dangerous.
Tools You'll Likely Need:
* Repair manual: Absolutely essential.
* Jack and jack stands: Securely support the vehicle.
* Wheel chocks: For safety.
* Wrench set: Various sizes, including metric and possibly SAE.
* Socket set: Various sizes, including metric and possibly SAE.
* Ratcheting wrenches: Speed up the process.
* Power steering fluid: The correct type for your vehicle.
* Drain pan: To catch old fluid.
* Floor jack (optional but highly recommended): To help maneuver the rack.
* Tie rod separators: To disconnect the tie rods.
* Torque wrench: Crucial for proper tightening.
* Transmission jack (optional but highly recommended): To support the transmission.
* Penetrating oil (PB Blaster or similar): To loosen rusted bolts.
General Steps (Consult your repair manual for precise instructions):
1. Safety First: Disconnect the negative battery terminal. Raise the vehicle securely on jack stands. Chock the wheels.
2. Drain Power Steering Fluid: Locate the power steering fluid reservoir and drain the fluid into a drain pan.
3. Disconnect Components:
* Tie rod ends: Carefully disconnect the tie rod ends from the steering knuckles using a tie rod separator. Mark their position relative to the rack for easier reassembly.
* Power steering lines: Disconnect the high-pressure and low-pressure power steering lines. Have rags ready to absorb any spilled fluid. You may need line wrenches to avoid damaging the lines.
* Steering shaft: Disconnect the steering shaft from the rack. This often involves removing a clamp or coupling.
* Rack mounting bolts: Locate and remove the bolts securing the power steering rack to the vehicle's frame. These bolts can be very stubborn due to rust. Use penetrating oil liberally and allow time for it to work.
4. Remove the Rack: Carefully remove the power steering rack. This might require some maneuvering, possibly using a floor jack to support it. The transmission jack is highly recommended here as the transmission may be in the way.
5. Install the New Rack: Install the new power steering rack, reversing the removal process. Ensure everything is aligned correctly.
6. Reconnect Components: Reconnect all components, including the tie rod ends, steering shaft, and power steering lines. Tighten all bolts to the manufacturer's specifications using a torque wrench.
7. Bleed the Power Steering System: Fill the power steering fluid reservoir with the correct type of fluid. Start the engine and turn the steering wheel lock-to-lock several times to bleed the air from the system. Check the fluid level and add more as needed.
8. Alignment: After reassembly, you must have your vehicle's wheels aligned by a professional. Improper alignment can lead to tire wear and handling problems.
9. Test Drive: Test drive the vehicle carefully to ensure everything is working correctly.
Warnings:
* Consult your repair manual: This outline is a simplified overview. Specific steps and torque specifications vary by vehicle.
* Safety first: Always use proper safety precautions when working under a vehicle.
* Fluid handling: Power steering fluid is harmful to the environment. Dispose of it properly.
* Professional help: If you're not comfortable with this repair, take your vehicle to a qualified mechanic. This job is complex and requires precision.
This process is significantly more involved than this brief summary. Again, you absolutely must obtain and consult a repair manual specific to your 1995 Chevrolet Lumina APV before attempting this repair. Improper installation could lead to serious damage to your vehicle or even injury.
