Do all 1995 or older Jeep have some slack in the steering?

No, not all Jeep vehicles from 1995 or older had steering slack. While some play in the steering is relatively common in older vehicles due to worn components like the steering box, linkages, or bushings, it wasn't a universal characteristic of all Jeeps from that era. The amount of slack would vary greatly depending on the specific model, its condition, and how well it had been maintained. Some Jeeps from that era might have had very little or no noticeable slack at all.
