My questions are:
1. Are the 31/28 spline axles the same diameter??? ( I thought the 31's were larger )
2. Do all BB housings use tapered bearings?? ( I thought some do and some you need to remove the seal to get tapered bearings to fit??)
3. So Can I get the 31 spline axles and use them in both my SM/BB housings with just changing the bearings??? ( I belive some BB axles use Non-tapered bearings.)

1: No they are not the same diameter. The 31 spline are quite a bit larger.
2: No. Either bearing can be used however I think most if not all used a sealed roller bearing stock. To use the tapered bearing the seal in the housing needs to be removed.
3: Not sure how they do the seals on the conversion bearings. The side gears in the carrier also need to be changed.
For those that are considering this it may be worth noting that you are beefing up the axle and in exchange for doing so you are running an even weaker bearing than the small bearing housing uses. (Larger ID with same OD equals smaller rollers and or thinner races) If you search the site here you can find a number of people that have had the stock bearings fail on the highway and then the axle walks out. I know some people have used them without problem but I personally don't like sacrificing strength in one area to beef it up elsewhere. (I would rather an axle break than have it walk out going down the highway)
