How do you adjust the steering gear box on a 1992 Lincoln Town Car?

You don't "adjust" a 1992 Lincoln Town Car's steering gearbox in the same way you might adjust a simpler, older system. The steering gear on these cars is a rack and pinion system, and it doesn't have easily accessible adjustments like older worm and sector gears. There are no easily accessible screws or nuts to tweak for steering feel or alignment.

Issues with steering feel or play in a 1992 Lincoln Town Car's steering are usually addressed by:

* Replacing the steering gearbox: If there's excessive play, leaks, or internal damage, the entire gearbox needs replacement. This is a significant repair job best left to a qualified mechanic.

* Checking and replacing tie rod ends: Worn tie rod ends can contribute to loose steering feel or poor handling. A mechanic can check their condition and replace them if necessary.

* Inspecting the power steering pump and lines: Leaks or low power steering fluid can lead to poor steering response. The system should be inspected for leaks and the fluid level should be topped up to the correct level (with the correct type of fluid).

* Checking the power steering pressure: Low pressure in the power steering system can be caused by multiple problems and can affect steering feel. A mechanic can test the pressure to determine the source of the problem.

* Checking the steering linkage: The entire linkage from the steering gearbox to the wheels should be inspected for wear, damage, or looseness.

In short: There's no user-adjustable "steering gear box adjustment" on a 1992 Lincoln Town Car. If you're experiencing problems with your steering, it's crucial to have a qualified mechanic diagnose the issue. Attempting to adjust the gearbox yourself could lead to further damage and potentially dangerous driving conditions. The symptoms you are experiencing will help the mechanic pinpoint the source of the problem.
