I used Maxima waterproof grease in there. I feel that with the off roading and wading that I do, it would be easy to wash out normal grease in there. Let's face it, the whole outer hub is about as sealed as a sieve. Water can get in, in all sorts of ways. I grease up the hubs well, including the main bearings of course, but I never cease to be amazed at how much seems to be missing when I come to strip it down a while later. I have been using a higher quality grease recently and it seems to make little difference. So I got some Maxima. It's not cheap but it's what the dirt bikers use in their motocross bikes and what have you. You can't get much into the needle rollers obviously but where the old style bushes were just metal on metal once the grease dissipated, at least here there are moving parts. These rollers are only a sliding interface if I can put it that way, they are not a third wheel bearing. Properly set up, the outer CV probably shouldn't even be touching them. The outer drive flange should be keeping the CV on the level. But if you have to replace tired old phos bushes in there then at least do the upgrade.
