Here's a breakdown of what could cause loose steering and how to address it:
Possible Causes and Solutions:
* Steering Gear Box: This is the most likely culprit. Worn-out internal components within the gear box itself cause excessive play or looseness. This usually requires a replacement of the steering gear box, a relatively complex and potentially expensive repair best left to a qualified mechanic. There's no simple tightening involved.
* Steering Linkage: The linkage consists of tie rods, idler arm, pitman arm, and connecting components. Excessive play or worn-out ball joints in any of these parts can contribute to loose steering. A mechanic will need to inspect each component for wear. Worn parts need to be replaced, not tightened.
* Power Steering Pump/Fluid: Low power steering fluid or a failing power steering pump will lead to loose or difficult steering. Check the fluid level (it should be between the minimum and maximum lines on the reservoir). If low, add the correct type of power steering fluid. If the fluid is dirty or brown, it needs to be flushed and replaced. A failing pump may need to be replaced.
* Steering Column: While less common, excessive play in the steering column itself could be a factor. This usually requires professional diagnosis and repair, often involving replacement parts.
* Bushings: Worn bushings in the steering linkage can lead to looseness. These are usually replaceable components.
What NOT to do:
* Do not attempt to tighten any components without proper knowledge and tools. Improper tightening can damage parts and create even more serious issues. You could strip threads, break components, or create unsafe driving conditions.
Recommendation:
Take your 1992 Chevy G20 to a qualified mechanic for a proper steering system inspection. They will be able to pinpoint the source of the looseness and perform the necessary repairs or replacements safely and correctly. Attempting DIY repairs on this system is strongly discouraged due to the potential for safety hazards.
