Another weird problem......I was tightening my rear diff screws and theoutdrives would only move freely if I loosened each screw 1/4 of a turn. Would I lose too much oil or is there something else wrong with the internal gears? Also noticed that if I move the rear hexes slowly there is this kind of binding noise, or maybe 2 gears are not connected to each other like they are suppose to? This is coming from the rear of the car. Can't decispher (sp?) whether it is the cvd or the gear that connects to the rear diff gear.
