I installed a 2" toytec AAL over the weekend. I am noticing that at driving at speeds over 45 its pretty loud back there. Almost sounds like I am driving with a window down (its not a squeak or anything). I noticed that I accidentally put the leafs in backwards, but I saw in a another post according to chris4x4 that this shouldn't be a problem but may cause axle wrap.
I am not noticing any serious vibrations other than the 20-25 mph range.
Any thoughts on what might be causing excessive noise?
