Brian,
Even though we carry AEV products, I would have to agree with you on the instructions for this kit. I think that they could use some refining and a QC check to boot. At one point in the instructions they tell you to drill a 3/6" hole, which should really be a 3/8", big difference. Also instructions should not have "Amendments". This was surprising to me because other AEV parts I have installed provide great directions.
But in the end, the finished product is worth the effort. I am really enjoying the ride quality. No driveline vibration issues on my end, but I am driving a 2009, so that could explain it. Looking forward to getting it out on the trail.
Best of luck with your rig!
