I believe it is clockwise to lock but i have searched this and no one is saying anything
Turn right or clock wise to lock hub and turn left or counter clockwise to unlock hub.
difference between locking and fixed hubs is fixed hubs are driven the whole time this means that the axles and hubs turn as the wheels turn these are engaged at the transmission when needed locking hubs are free wheeling hubs, and when not locked the wheels will turn but the axles are not turning some have a switch inside cab to lock them, some you have to get out of vehicle and manuelly lock the hub at the hub these hubs when unlocked will not drive when transmission is engaged,
put in manual hubs. that is the best way to make sure that they get locked in every time.
If you have manual locking hubs they lock when you turn clockwise. This engages the wheels to the front axles and the front differential. You can then engage the 4wd from the cab lever. If you unlock the hubs (turn couterclockwise) they disengage and "free wheel" This position saves a little fuel since you are not spinning all that heavy steel in the front differential all the time. You should always engge the hubs a few times per year even if you don't use the 4wd. This allows all of the oil seals to turn and get new lubricant.
In most cases just buying a new set of hubs. The automatic hubs are spring loaded and have an internal locking mechanism that works with the axle as to manual which just locks on to the axle when you turn the dial . Very easy swap just make sure the manual hubs are for your vehicle .
a 95 4 runner probably doesn't have locking hubs. it probably has a.d.d. or automatic disconnect differential which means the hubs are always locked. so all you have to do is shift the transfer case lever into 4 wheel drive.
I have a 2005 which does have locking hubs, but that is so you can lock your differential from slipping. If you're stuck on a hill with all 4 wheels spinning, lock the hubs and your gear ratio is far apart, your front wheels won't spin, and the front wheels will actually do the pulling. Whether yours has locking hubs depends on the year of F250. Later F250's, I believe beginning with the 1998 models, do have auto-locking / manual hubs. The later F250 hubs can be activated manually or electronically. When you electronically turn on the 4wd ("shift-on-the-fly"), you engage the transfer case, front drive shaft, and front axle shafts. Also, when you electronically turn on the 4wd you activate a vacuum solenoid, which provides a vacuum source to each of your front hubs to engage them. The front hubs only connect the front wheels to the front axle shafts and has nothing to do with the front axle differential, which is an open differential unless you have a differential other than the factory installed piece.
Twist the center section about a quarter turn. If it does not want to turn it is frozen. They can either be rebuilt or replaced. Since Ford uses plastic and dissimilar metals that cause the frozen issue, aftermarket such as Warn is an option.
Did you lock the hubs on the front wheels? They might turn with just your fingers, but sometimes you need to "help" them with a pair of flat pliers. Turn the arrow to LOCK or ENGAGE. When you are done, just turn the hub back to freewheel. If you have automatic locking hubs ( it will say AUTO on the hub) and you don't have 4 wheel, one or the other hubs may need replacing.
a quarter turn before you strip the nut out
If you have the ESOF (Electronic Shift on the Fly) option, the F250 SD 4x4 comes with auto locking hubs from the factory. They lock and unlock by themselves when you select 4 wheel drive on the dash. This is accomplished by the turning of the axles after they are engaged by the transfer case. The unlocking is also done automatically when the transfer case releases the axles and spring pressure in the hubs return the spindles to free floating. If you have manually locking hubs,... well that speaks for itself. I have replaced my auto locking hubs with Warn manual locks. Superior, trust me. Besides, I'd rather lock my hubs and turn the front diff, knowing that when I need the 4x4 it's gonna be there, instead of wondering whether the auto locks are going to engage after not having been used all summer. If you do not have the ESOF option, it's old school: get out and turn the dials on the wheels then shove the lever into 4x4. If they won't turn, it is because they have seized, which is a common problem on Fords. You will need to remove the assembly and repair or replace. If you have ESOF, you can ignore the problem and assuming the ESOF never fails you, you won't need to turn them. ON ESOF, the manual turning of the dials is only a backup system if the vacuum assist of the ESOF fails.
I have a 2000 tacomaa 4x4 and it has manual locking hubs. I have to physically get out and turn the lock. so I dont think so unless it has been customized.
