I removed the 'OEM' Warns and installed solid axle minitruck Aisin hubs on my '78 FJ40 and I have been running them without the snap ring. I don't wheel is super hard - any likely problems from this? I presume the birfield rubs on the inside of the axle 'bell', right? Any other wear or strength issues?
