Sorry to hear about your KJ drowning....
For my own KJ I've had the usual front brake discs warp problem and lower ball joints recall ( 2 times ).
I still have something else: when I steer to the left ( turn the wheel till it doesn't go any further ) when parking or doin a U turn at coming back to center position at times I hear a very loud 'CLOING' sound. I've checked suspension myself and don't see anything. Complained about it every time I took it into the dealership for it's regular maintanance, they say they cannot find anything wrong with it... Can it be the spring rubbing against the top suspension arm?
