I use Paris Racing's "Ronnie" Grease. It's dark green and pretty sticky. My CVD/LCD/RCD joints last a long time between rebuilds. Just gotta clean them out and re-apply grease once in a while. Sadly, one can't find "Ronnie" grease anymore.
Tamiya's AW grease would probably prevent wear better than most but that grease is just too dang sticky. Can't help but think it would slow the car down somehow.
