Looking for Maintenance info on a 2006 Jeep Grnad Cherokee

[Batphreak]

My in-laws have a 2006 GC with the 4. 7L and quadratrac all wheel drive. It's time to change the driveline fluids in the transfer case and axles. I know the axles take 75W-140 synthetic and the transfer case is ATF+4, I'm guessing 4qts for each axle and 4qts for the transfer case (if anyone has actual capacities that'd be great). The real trick is I'm going to have to do this at their garage, so I won't have my whole toolbox there. Does anyone know what size socket I'll need for the front and rear pumpkin covers? Also, I'm assuming the plugs in the transfer case take a big allen key, anyone have that size, or what type of plugs they are? Just figured I'd see if anyone has the info so I don't have to take half my toolbox along, hopefully I'll just need a small set of sockets, allen keys, hammer, and putty knife for tools, then some RTV and pipe selaer to seal it all back up. Done this job plenty on trucks, but not on a little Jeep. Thanks a lot!
