Front CVD's grease or no grease ?

[andys]

Just building my 410 and noticed there are no cvd boots for the front, wheel side CVD's.

My 410R didnt have any boots and the front outdrives wore very quickly, I've seem others look very worn too so I guess it's normal in Durango land.....

Question is, do people bother greasing them as surely it just attracts muck into the CVD, or is it a good idea to get some more CVD rubber boots for the front or run them with no grease ?
