Wanted to follow up with this thread as a way to notify other members with dynaloc hubs.
We just rebuilt the wheel hubs on a 2006 front prorock 60 that has the dynaloc locking hubs.
New bearings + races + seals + locking spindle nut + grease.
Taking the drivers hub apart showed wear to the dynaloc outer lock (it was and is difficult to transition from 'O' to 'X').
Ordered a new outer lock and two bronze pilot bushings.
Anyone with an older prorock 60 might want to check their dynaloc hubs and if there are no bushings between the inner and outer lock, contact dynaloc to purchase the pilot bushings ($10-each) as they help to minimize movement and wear to the outer and inner locks.
The following pdf instructions and youtube video both highlight the pilot bushing...brass in color in the video.

Also, upgrading to stage 8 spindle nuts is an excellent way to ensure wheel bearings remain seated...cheap insurance. and the stage 8 uses a 4-pin spindle socket to install, which seems to provide more stability during install/removal than the 6-pin spindle socket.

Lastly, this is a worthwhile tool for any DIY'rs who repack bearings... Lisle 34550 or other
