I think this is the crux of it. In my youth dealerships employed mechanics who learned through training and extensive apprenticeship, with a strong emphasis on understanding how things actually worked. Now the process is heavily automated and driven by if-this-then-that procedures, without really needing to understand, for example, what too much or too little caster actually does and how to correct it. Sometimes you just need a mechanic. A real mechanic.This!
The "steering issue" did not impact all JLs off the factory line. Only some of us had the joy of managing our own resolution with dealerships that had no idea what to do.
Mine went from 1" of slop originally when the steering wheel was centered to rock solid now. In my case, the fix was a new track bar, steering box, software update and longer mopar LCAs.
Love the steering now!
Twelve years ago we bought a new Class C RV that was built on a Ford E350. One morning, about 350 miles from home, the RV would not go into Drive, so it had to be towed to the dealership. It took two full weeks to fix the problem, because the automated service manual and Ford’s remote technical advisors kept requiring the replacement of various “modules”, each of which had to be shipped to the dealership. In the end, the problem turned out to be a single faulty wire that was shorting out on the frame, but nobody thought to consider that possibility — because nobody at the dealership knew that a short was capable of producing that failure.
