to follow up on this i spoke with a guy at argo. There are more reasons for the argo to leak water and for the axle to have movement ...its not always the bearing. Over time you will see two wear marks where the outer seals rub grooves in the axle, this will cause a leak. Secondly over time the bouncing over bumps...the bearing will actually wear down the axle. So if you install a new bearing with a worn down axle there will always be play and the bearing will wear out in no time. You can swap axles from the front with the axle extensions and use these in the back but eventually these axles will have to be replaced.

I talked to argo too. That is why I,m building mine with duuble sealed bearings with double extended inner races on the outer bearings, which accomadates a outer seal that rides on that extened inner race instead of the soft axel. As for the bearing wearing out the axel. sounds like the bearing collars should be tightened down more. There is no excuse for the bearings inner race to wear the axel down. Any macheinists out there that would like to comment on this?

I agree with you on the axel problem. The bearing should act as a bearing; not as a sleeve. The inner race should fit tight on the axel.

I have just bought a used 2001 Bigfoot and am reading the bearing stuff. As a machinist with 37 years experience in the trade, I will have to wait and see when the bearings become an issue. The last post that bearings should be tight on the shaft is absolutly correct and anything else is just ruining new bearing shaft seat diameters. There is a "range" of acceptable diameters for any given bering. This range is usually just a few tenths of a thousadth of an inch. Thats .0001 of an inch. If the shaft is to big the bearing will wear out the rollers from the inside. If the shaft diameter is to small, the shaft seat of the bearing will "work" on the shaft and further damage the shaft and also the shaftseat diameter of the bearing will be ruined so even if you do get "correct" replacement shafts, you won't be able to use those bearings because they will be too loose on a correct shaft and will ruin the new shafts. Ya gotta have everything right at the same time. I hope I made this clear enough for a non machinist to grasp.
