Most likely whenever the clamp was damaged - so was the stabilizer and now is short on travel so cant make both left and right extremes - and when suspension travels (like turning into a driveway and going through bump omn one side and rebound on the other) it needs more that just ain't there!
The stock clamp is okay - until you hang it or bend it after which it will be very unpredictable. You are headed in the right direction replacing. Keep in mind some of that unpredictability and coming loose is from the gouges put on the tie rod - make sure to address that with either a mill file or replacement with a chromemoly tie - replacing the tie is a good idea - if you dragged the clamp you may easily have bent the tie. Will still work but once bent it gets "spongy" on the obstacles..
When you put it all together attach the tie rod end last. Center the steering, pull the stabilizer all the way out (full extension) and mark the tie rod where the eye is. Then push it all the way in (full compression) and mark the tie rod again. Then simply mount the clamp with the stabilizer eye bolt dead center between the two marks. Leaving the marks aids in future checks to make sure nothing has moved.
Does your high mount kit come with the tie end clamp? Many use the stock turned over. Link
to the clamp I prefer - it does not hang harshly on rocks and the clamp is centered to the eye bolt - not offset like stock design.
