I installed my AAD/Direct connection rear anti wheel hop suspension in my charger this weekend and could not get the last bolt into the cradle. After 2 hours of frustration I gave up and figure I would let the dealer do it when they do the alignment.
So they found the problem all right....the front and rear bolts are different length and I put them in backwards! I felt like an idiot. But they got it all set up and aligned and said the stuff aligned dead nuts and were very impressed with it.
I had watched the videos of just cutting the front bolts, but preferred to do things right and drop the cradle to get to them. That decision cost me an extra $200 at the dealership.....
