99 tahoe, completely stock.....went out today to do a small crank to bring up the front a little and ran into what could be an issue but i'm not really sure. when i got underneath the truck, i quickly realized that the bolt on the drivers side appears like it may have already been cranked??? theres only about 3/4", maybe less, sticking down BUT on the passenger side the bolt is much farther down, like another inch. i then measured the ground to fender at each corner, the rears were at 37.25", left front was at 37", and the right front was at 35". WTF is going on? then when i went to adjust them i couldnt get them to budge at all. i think i'll try tomorrow after letting some penetrating oil soak in but i'm stumped as to why they are different side to side.
