i have a 1988 sliverado 350 5 speed 4x4 1500 single cab short wheel base with automatic hubs and the front wheels wont pull and no popping or grinding noise at all and the transfer case will let you put in all 4wdL 4wdH N 2wd put the wheels wont pull and the light doesn't come on
A stuck/frozen e-brake cable could do that.
take it to the dealer........
2001 kia sportage will not lock into four wheel say it in four wheel drive but front wheels dont pull or lock in
check the shift linkage from the dogleg to the transfer case.the bolt on the linkage may have come out causeing it not to lock it
A friend of mine had the same problem and he just had to jump out and lock the hubs manually to get his 4x4 working.
What is the n onthe 4 wheel knod
Yes, assuming the car has four wheels, four-wheel-drive is the same thing as all-wheel-drive. Not always, four wheel drive provides a positive lock between the front and rear axles. All wheel drive has a differential between them most of the time.
You'd have to remove the trim from the door. The lock tumbler is typically held in by some sort of clip... you remove that, and the lock tumbler should pop right out.
Probley have a bad 4x4 Actuator in the front left side of the differential HOUSING. It is towards the center of the housing on the left when standing in the front of the truck.
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.
With a hanger
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.
