Do I put any grease on the knuckle wiper? I packed the trunion bearings, birfield, and put some grease on the inside of the knuckle(where the birf spins). Theres not any moving parts in there, but it could help seal out the water.

i never have before,it will get it soon enough...

I didn't, and mine have been just fine for about a year's worth of grime, mud, dust & snow, but I also don't see how it could hurt to put just a thin layer on the rubber wiper part just in case it takes a little while to get some. Probably unneccesary though.

No you don't put it on the wiper, etc.

Just did a rebuild on my FZJ80, no need for it there either.
