    What is the difference between a Full floater and a Semi floater 14 bolt? As I understand it the FF is better, But I'm not sure why......is it true that in order to replace the rear brake drum (or pads) on a FF you have to pull the axel shafts??
    Thanks for any info.

    FF are easy to change axles. Pull the bolts on the hub and pull the axle out. The FF is stronger because the axles just transfer power, where as a SF axles hold the weight of the vehicle and transfers power. That and when you break an axle in a SF the axle comes out and leaves you stranded.

    yep to do bakes on a FF you have to pull the shafts and the hub assy.
    Or convert to a disk setup.

    <font color=blue>The FF is also stronger since all the parts are larger. The SF has a 9.5" ring gear and 1.31" shafts, and the FF has a 10.5" ring gear and 1.5" shafts. They're two tottally different axles

    And you can pull the axle out without taking the wheel off on a 14ff. They don't have c clips so if you do brake an axle on one the wheel won't fall off.

    my 14b SF is an eight lug. it's fine for now but once i break it i want like a dana 70 or 80. EVERYBODY and their mom has a 14bff and a d60, so when i upgrade, i'm gettin a dana 80, hopefully. is a dana70 stronger than my 14b sf?

    people that get good mileage aren't having any fun!

    Probably the SF since its alot lighter, but if you start wheel hopping and break an axle, dont expect to drive home. The FF gives lets you get home if the axle breaks.

    Only if you have a way of keeping the broken axle shaft from leaving the housing. You might be able to do drive it with a broken shaft if you have disc brakes but not likely with the stock drums.

    There is a Dana 80 Hybrid out there which consists of a Dana 80 center section and Dana 70 axle tubes and axleshafts.... They can be found in some Cummins powered Dodges....

    As like Forest says, " Thats all I have to say about that!"

    From what I've seen, the 8-lug 14SF is very common. It was the standard axle found under 3/4 ton pickups and Suburbans starting sometime in the early to mid-80's and I think may still be used in the new Silverado trucks also. The 6-lug versions are fairly scarce since they seemed to only have been used in some light duty 3/4 tons and a few 1/2 tons (with various comibinations of towing package) starting in '88 when the new body style with IFS was introduced. It also seems as if they maybe stopped using the 6-lug 14SF in the 3/4 tons at some time as I haven't seen any trucks newer than maybe the mid 90's that were 3/4 tons with 6-lugs (though they could very well be out there).
