Just thought I would share some notes.
I have the corp 235 anti spin rear axle, 215 front axle, and borg warner 44 transfer case. Just reached 40k miles and thought it was time to change all the fluids.
1) Front axle - remove drain and fill plug using 3/8 socket wrench. Drain fluid. Using a hand pump, fill back up with syn 75w-90 to bottom of fill hole, a little over 1 quart. Reinstall drain and fill plug.
2) borg warner 44 transfer case - remove drain and fill plug using 3/8 socket wrench. Drain fluid. Using a hand pump, fill back up with Mopar Borg Warner 44 transfer case fluid to the bottom of fill hole, about 1.5 quarts. As of right now, there is no other compatible fluid on the market for this BW 44 transfer case. Must get it from the dealership at $27 bucks a quart. So try your best to minimize any spillage or waste of this liquid gold. After fill up, reinstall plugs to about 20-25 ft lbs.
3) Rear axle - No need to remove diff cover for this procedure as there is a drain plug. Remove drain plug using 14mm hex. Remove rubber fill plug. Drain fluid. Refill with syn 75w-140. If you have anti spin, also fill with 4 oz of limited slip additive. Fill to bottom of fill plug, about 2.2 quarts. Reinstall rubber fill plug, reinstall drain plug.
