    Welcome to the fourms! Don't worry, it's normal for some grease to leak out like that. It's coming from inside the diff, and it slowly leaks out threw the bearing. Don't worry, it can't hurt anything. The bearing is fine also, just make sure you wipe the grease off, or else dirt and crud will stick to it. Hope this helps!

    So as long as you keep it clean it is not a problem? What if all the grease eventually comes out?

    Ya, as long as you keep it clean all should be well. Yes, after awhile the grease will get low, and you should clean out the old grease and re fill it with fresh grease.

    Fill it with diff oil, not grease. There is a big difference in performance.

    It should not really leak out and cause a big wet spot though. Check the diff seals, and if there is more oil inside the diff bulkhead, there could be a problem with the diff o-ring.

    You only want diff oil inside the actual diff cup with the spider gears. It shouldn't leak from there. It's sealed with bearings and a gasket.

    You should have grease on the ring/pinion.

    To carry on with the Diff oil/ grease idea... Whats a good all around bashing viscosity for the rear? 10k 100k 500k? And what grease do you like on the ring and pinion, is white lithium ok?

    30k weight in rear, 50k weight if front is the most common suggest viscosity for the diffs on the the P4de. Although tune to your liking. The thicker the oil the less slip in diff. What ever grease you like on the ring and pinion. White lithium is good. I use basic packing grease for 1:1's. Some use marine grease.
