MX5100 Front axle pivot zerks

[crystallake]

Last weekend I did some grease and lube work around the tractor. Greased the front pivot, taking out the relief plug and pumping grease in until it came out the relief and then a little more to get good clean grease inside. Then moved on to the next zerk to the rear of the front one, on the drive shaft. The thought came to me...where is this grease going?? There is no relief port, I do not see any coming from a seal. Just learning and wondering. I looked up the parts diagram and it looks just like the front bushing but with no exit hole. Anyone know the answer?

When you get some hours on it and the pivot loosens up a bit, you'll see the grease oozing out around the axle boss. I only give mine a couple strokes, it don't need a lot, not much movement there.
