The long story: Got a 89 s10 blazer that we just picked up a while back with a busted rear end. We convinced them to let us on base with it, even though the out of state registration was expired, cause afterall it was disabled and couldn't be driven. We told them it would be fixed as soon as it can and we would immediatly get it emission tested and registered (and we will). Well we've been looking for a set of axles for it, so we can swap the rear and do a solid front axle conversion at the same time. It takes a while to do things like this, but we are trying. So anyway, we see the Security Forces snooping around and looking at it here in the dormitory parking lot, writing stuff down on a piece of paper and all . So obviously that makes us a little nervous, who knows how long till we walk outside and it's just gone. Trying to avoid that. The basics: So we can't drive it to emissions testing with the rear end hooked up, so can I pull the drive shaft? Wouldn't the rear t-case come with it? I can't spill oil in the parking lot, so how high it the level? Can I pull the slip yoke without it gushing out? Or is there something in that posi diff(diff is already drained) I can quickly pull out to disengage it? How far could I/should I drive without a yoke?
