I recently put a BB on my '99 XJ (AW4, 231, HP30, Chry 8.25). The front is up 2"(spacer) and the rear is up 3.5"(full length AAL). I now have a droning sound at 34 mph - it sounds like I have an aggressive MT tire, but I don't. At first I figured it was a DS vibe, but I drove around and don't feel a thing in the t-case handle. Also, I get the noise no matter what RPM range I'm in. It's a total guess, but could I just be hearing wind noise off the front skid or something - since the body sits up higher now? Any help would be appreciated.
