I recently was run off the road and sustained some damage to the steering rack and a slight bend in my frame. The frame was corrected and the passenger side underside damage repaired. Since the accident I have had some minor problems, some of which I was savy enough to diagnose and repair. Seemed like an inexperienced mechanic may have rushed through the job. A few problems remain: the yoke snapped in the front differential and I am without 4wd. Pretty sure I will have to dismantle it to replace the front drive shaft, and I lost a great deal of turning radius to the left, driver's side.
Not long ago I slid underneath to find the cause of a thumping sound that was heard going over bumps. I found that the drag link was slightly loose against the steering gear. It sparked further investigation and I saw that when I turned the wheel left it seemed to stop before hitting the stops, maybe 7-10 degrees. Is it possible that the Pittman arm was slid on just one spline too far right on the gear? Would this account for the loss of radius?

I am planning on replacing the hub and knuckle this winter, used a non ABS replacement leaving me without the feature and thought with the whole side off I might as well try to get the truck back to the tough and glorious condition it once enjoyed. I love my Loch Ness and have sent enough fixing it that I want to take care of my investment and keep my ride safe. Any help?
