IRT steering box adjustment; I do not have the same model as you but .... The majority of loose-feeling steering issues (beyond the one inch) can generally be traced to steering component wear such as tie rod or ball joint. Be wary of adjusting the steering box play. It seldom needs attention so long as the lubricant level is maintained. Many people try to take the easy way out of front end problems by adjusting the steering box. The results are often disappointing and result in a damaged steering box PLUS the original front end component problem.
