I hear Superwinch makes a good replacement for the 5 bolt, don't know about Warn. I have heard of people swapping the front rotors with a '78-'79 CJ to get the stronger 6 bolt hubs, but I swapped out the whole axle to get them (added benefit). I used to have probelms with my hub bolts loosening, so I removed the bolts and replaced them with studs, a huge difference. They never loosened and never broke. I grenaded an axle and ripped shackles in half, no problems with the 5-bolts, but I think I was just lucky.
