I just ordered '00 F250 SC 4x4 SWB XLT with the factory standard manual hubs. The hubs show up on the vehicle order confirmation as code "21M MAN LOCKING HUB". I can't find this code in the ordering guides anywhere but kbb.com shows this code as "Manual hubs delete. Required with 213 shift-on-the-fly". I want the manual hubs. I think ##### is incorrect. For my piece of mind, could someone who has also ordered the factory standard manual hubs verify that the code is indeed 21M. And for those who ordered shift-on-the-fly, could you verify that 21M does NOT show up on your order confirmation (I don't want to leave anyone out of this little exercise). Thanks.
The code for my '99 250 4x4 V10 with SOF is also 213. I've looked on my order confirmation sheet and also on the list of available options (a photocopy from the dealer book) and that code 21M doesn't show up anywhere. Maybe it's a new code for the '00 model year?
I have (had) the auto lock hubs. Bought a set of Warn manual hubs, removed the vacuum lines, auto hubs, and the screw in vacuum nipple on the back of the knuckle. Filled that hole with a 1/8" NPT pipe plug and capped the vacuum solenoid output on the right side of the radiator. I then installed the Warn manual hubs. Now can use 4 low in 2 wheel drive (2 low) and get awesome torque with bind freesteering with the simple turn of the lazy ****. I love it like this.
