#6 the center of the vehicle and the plugs are at the rear of the case. These are NOT o’ring plugs like the differentials were. They are tapered plugs with no seal which seal simply by screwing them into the case. Again, remove your fill plug first, then your drain plug and let the fluid drain. Clean out your pump that you used for the differential fluid and fill the unit through the fill plug with the transfer case fluid until it runs out the fill hole. Let the fluid drip until it is done dripping and replace the plug. CRITICAL: This spec for the fill and drain plug is 15 ft/lbs. If you tighten this too much, you will crack the transfer case which becomes extremely expensive. You should be using a 1⁄4” torque wrench and not a 3/8” as the larger torque wrench will not be accurate at that low of a setting. Note: the plugs may sit slightly higher than flush when installed properly, so don’t think you need to get the plugs flush in the case. Again, nothing is under pressure here, you are better off a little loose and if you notice any drips, then carefully snug up the plug. Cracking the case is a bad deal.
