    I'm a total newbie on drivetrain so I figured I'd ask the experts. The pinion bearing is starting to go out on my 10 bolt so instead of messing with it i want to upgrade. Van axles are plentiful here and i like the matching width factor they will provide. I'm wanting to stay six lug as a FF is overkill for what I use this /forums/images/graemlins/k5.gif for. Just mud and snow, no rocks so I'm looking at the 14SF. My /forums/images/graemlins/k5.gif is a 90 so it has the ABS on it. Do I need to find a newer one with the ABS or what? My yard here handy has a 88, 94, and 95 right now. I'm sure I will have to move the perches around but what would be the least difficult swap. Also what about the yokes? Will I need a conversion? By the way, my height and everything is currently stock but I am looking at going around 4" soon. Any suggestions you can throw at me will be great.

    Don't worry about ABS. Your K5 uses the speed sensor in the t-case for this. There are no sensors in the rear end.

    Find out what overall width you need. 2wd and 4wd versions of the 6-lug 14SF differ by about 3-4". (4wd is wider)

    A conversion u-joint will probably be necessary. the 14SF pinion is only 1/2" longer. Your driveshaft slip-joint can probably accomodate this. If not, the 4" lift will.

    One problem you will run into.
    No Van came with 6 lug /forums/images/graemlins/frown.gif

    I had a van and was converting it to 4wd and did all the research to find a 6lug van width to no avail, so I switched to 8lug.
    They only come in 5lug and 8 lug.
    I haven't seen what the 2000 and up have but I wouldn't be looking at those axles anyway since they still are too expensive. /forums/images/graemlins/grin.gif

    What about an axle off a 4x4 van? I know FedEx uses 4x4 Savannas. I always forget to look to see if they're 8 lug or not. They probably are. Since FedEx vans are independently owned they do go up for sale once in a while. They usually go in cycles of 3-4 years where you'll see a bunch of them for sale for cheap.

    Well if there's no six lug van (I'm going to call the yard tomorrow and check on theirs they had listed to make sure) what would have a 14sf six lug under it? I could always run spacers I guess.

    88up high GVW half ton pickups. Some 3/4 tons. You'll be moving spring perches and shock mounts. It'll also have 14mm lugnuts instead of 7/16".
