However, I can outline the general procedure and highlight crucial points. You should consult a repair manual specific to your 1991 Chevy Corsica before attempting this repair. A Haynes or Chilton manual will provide detailed instructions, diagrams, and torque specifications.
General Steps (Consult your repair manual for precise details):
1. Safety First: Disconnect the negative battery terminal. Support the vehicle securely on jack stands.
2. Fluid Drainage: Drain the power steering fluid. Use a catch pan to avoid spills.
3. Component Removal: This is the most labor-intensive part. You'll likely need to:
* Disconnect the steering linkage.
* Remove the tie rod ends.
* Disconnect the pressure and return power steering lines. Be prepared for fluid leakage.
* Remove any brackets or components obstructing access to the rack and pinion.
* Unbolt the rack and pinion from the vehicle's frame. This will likely require removing various bolts and possibly other suspension components.
4. Installation of the New Rack and Pinion:
* Carefully install the new rack and pinion, ensuring proper alignment and seating.
* Reinstall all removed components in reverse order of removal.
* Tighten all bolts to the manufacturer's specified torque settings (found in your repair manual).
5. Bleeding the System: After installation, you'll need to bleed the power steering system to remove any air bubbles. This is typically done by turning the steering wheel lock-to-lock while someone adds power steering fluid.
6. Alignment: After the repair, a wheel alignment is absolutely necessary to ensure safe and proper handling.
Important Considerations:
* Specialized Tools: You'll likely need a variety of tools, including various sockets, wrenches, a pickle fork (potentially dangerous, use caution), a power steering fluid pump, and possibly a steering wheel puller.
* Torque Specifications: Incorrect torque settings can damage components or lead to failure. Use your repair manual to ensure proper tightening.
* Fluid Type: Use the correct type and amount of power steering fluid specified for your vehicle.
* Safety: Working under a vehicle can be dangerous. Use jack stands and always follow safety precautions.
Recommendation: Unless you have significant experience working on automotive steering systems, it's strongly recommended you take your vehicle to a qualified mechanic to have the rack and pinion replaced. This is a complex repair with potential safety consequences if done incorrectly. The cost of professional repair will be far less than the potential cost of an accident caused by a poorly installed rack and pinion.
