Operational Check, 96 Ford F250
Source: by Jim G at alldata.com

Operational Test; Remember to block the wheels. This would work for testing manual hubs too, just lock them 1st; "...Place transfercase in 2HI or Neutrall. 2. Lying under vehicle, turn front drive shaft (one direction only). 3. Automatic hubs should lock after 1 to 5 turns of driveshaft (one direction only). After step 3 the hubs should lock, youll know they are locked becouse you will hear a click from both hubs and you will no longer be able to turn the front drive shaft (in the same direction). If this is not the case then continue to step 4. If you can no longer turn the drive shaft (in the same direction) then skip to step 7. 4. If you can still turn the drive shaft (one direction only) then one or more of your Auto hubs is not working. 5. Continuing to turn the Drive shaft (one direction only). 6. Look at the u-joints for the front stub axles, if both are turning then both front hubs are malfunctioning, if only one is turning then the one that is not turning is locked and the one turning is malfuctioning. Replace as necosary (preferably with manual hubs, Auto hubs have Yams in them) 7. To unlock the hubs, turn drive shaft in opisat direction untill you hear a click from the hubs. To check for transfercase engagement. 1. Place pushbutton transfercase in either 4 HI or 4LO. 2. lie under vehicle. 3. You should not be able to turn front drive-shaft in either direction. 4. If you can turn the front drive shaft then your transfer case is not shifting properly..."

Wheel Bearing Locknut Torque Settings for 80-96 MANUAL HUBS, NOT Factory Auto Hubs; Ford Pickups and Bronco; "...Using a lockout spanner (Ford # T59T-1197-B or equivalent) and a torque wrench, tighten the inner bearing adjusting nut to 50 foot pounds while rotating the wheel back and forth and seating the bearing. Back off the adjusting nut approximately 45 degrees. Assemble the lock washer by turning the inner lockout to align the pin with the nearest hole in the lock washer. To lock it, install the outer lock nut and tighten it to 150 foot pounds. Grab the top of the tire with one hand and the bottom of the tire with the other. Move the tire in and out on the spindle. End play should be less than .006 – inch.).." Thanks to 90beater (Topher, Chris)!!!!
