Best Answer

On part time 4 wheel drive vehicles, there are quick turn locking mechanisms on the front axles that either egage or disengage the wheels to the front drive shafts coming out of the front differentials. Unlocking them helps save on gas as well as wear and tear on mechanicle parts by letting the front wheels spin freely when not using four wheel drive. The transfer case diengages the other end of the drive train from the front end.

How do lock out hubs on a 4 wheel drive work?

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.


Why does your 1994 gmc four wheel drive not lock in?

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.


How do you reverse the front hubs on a 2001 Kia Sportage?

You cannot do it. The anti lock brakes get their coding information from the hubs. So, if you reverse them your anti-lock brake light will keep coming on. Just get the hubs from Autozone and do it correctly.


What is the difference in locking hubs and fixed?

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,

How do you lock front hubs?

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.
