To slow the gears down quickly when shifting and to prevent leaking. The rear doest need to slow down because there is constant mesh. On your steering box, you'll note two bolts, one is a pipe threaded filler plug. The other is an adjustment for the bearings in your steering box. Do n't tighten this one too much, just snug it. No tightening it! It snugs a race up against a bearing and too tight cracks it and you'll have a click in your steering wheel as you turn it. Remove the drain plug and check the fluid. Normally, this also takes 600. However some of us have found that John Deere , Cornhead Grease works very well. It's cheap ($3-4 a tube) and it's pretty available and it doesn't leak out. So there, you have plenty to work with. Good Luck!

I could have written the above. We use 50/50 mix STP and 600w oil from MAC’S in transmission and rear end. Cornhead grease In steering box and u-joint.

Enjoy.
