I just reread your post and realized what you were asking. Doh For some reason I though which drop I had used. Sorry, read it first thing after waking up.
On take off I had a bit of a soft banging/knocking noise that consisted of about 4 knocks. Funny thing is that I guess there were more vibes at faster speeds that were subtle that I thought was due to the tires and was not really vibes but tire noise. It didn't feel like any kind of shaking, just noisier. Since one of the POs had put on the lift and this was my first Wrangler, I had nothing to compare it to. Only reason I noticed was that after doing the drop, it drove so much different. The bad news was that I knew that the front driver side never had a bolt and it has been fine up until now. The thing is that right before I bought it, there was some transmission work done by a small garage who obviously knows nothing about jeeps and they had cut (yes cut) two small holes into the inside of the frame to put nuts inside for the middle and rear holes for the skid plate as all of the nuts on the driver side had started spinning. For now, I am keeping it as it is but come spring, I am going to do the nutsert fix as per the following link: http://www.jeepforum.com/forum/f37/nutsert-nut-insert-installation-19850/
What a bunch of boneheads. The one advantage of taking it to a dealer is you wouldn't have seen this been done.
I think getting the holes welded shut as well wouldn't be a big deal.
went wheeling @ rausch creek yesterday( very icey )
im pretty impressed with the smittybilt rear bumper and tire carrier thus far, it took a couple good whacks when i slide down the ice on a hill and smashed into a tree.
also very impressed with the aussie up front, the difference is night and day compared to being open up front, you can really feel this thing pull... or TRYING to pull you on a hilly sheet of ice.
then broke u-joint on front drive shaft while dicking around on the comp course @ the end of the day, pulled front drive shaft for the ride home.
i went wheeling there as well. however, i escaped damage/carnage free. made it up an ice hill with an open dana 30 front and half bald MT's. but did get pulled up a smaller hill. today, emptied the trunk load of tools, and wiring up my reverse fog lights.
