Lock out hubs release a tensioned spring that holds a splined gear over the outter end of the front drive axle. These cogs are splined to the axle on their inside,and geared to the hubs on their outside perimeter , making the connection between the two when locked in. These are located on each outter axle end ,in the hubs, at the center of the front wheels. When unlocked the front axles and front driveshaft are no longer forced to turn with the tire.
check the ft. hubs, see if there is a dial to lock them. If theres no way to lock hubs or no dash switch than its a 2 whl dr. vehicle
i believe its a automatic friction lock if u don't have manual locking hubs
If You have Manual Locking Front Hubs, Then the 4 wheel drive will not work/drive the front 2 wheels at all without, Locking-Them-In . Do Not Lock and use the 4 wheel drive on Dry Pavement.
If you have lock outs or free spinning front hubs, you turn the center of each front hub to lock them in. If you don't have lock outs, they lock in when you put it in four wheel drive. To unlock them, take it out of four wheel and slowly back up 3 to 5 feet.
The best way to repair an auto locking hub is to throw it away and get manual hubs. You will get better mileage and when you lock them in you know the hubs are locked in.
you change the settings Turn the knob Pull the lever Lock in the hubs
Need more specifics on this question. What isn't locking in? does the transfer case lock in? Do you have aftermarket hubs? Sometimes you need to make a full tire rotation backwards for the hubs to lock. The hubs could be broken inside.
NO... There's no way to install manual lock-outs because of the way Chevy designed the drivetrain / axels. After 1987.
The hubs lock the axel to the hub, which drives the wheel. With the transfer case in 2WD, the rear driveshaft drives the rear wheels. Without front hubs, in 2WD, as the front tires roll, they spin the axles and the front driveshaft. With lock out hubs, in 2WD and the hubs unlocked only the tires spin. However, in 4WD if you forget to lock the hubs, only the driveshafts and axles spin. When I lived in MI, in the winter I always kept my hubs "locked", this way I could shift into 4WD whenever I needed to without getting out in the cold to "lock" the hubs.
did you get out of your vehicle and physically lock the hubs on the front wheels? there automatic locking hubs.
It means that you do not have to get out and lock your hubs when you engage 4 wheel drive, most all vehicles use this method now.
your front hubs are still locked.make sure it is in 2 wheel drive,and try backing up to release them.
