Place vehicle in 4wd (high or low). This will hold the front drive shaft still for the rest of the test. Jack up the front end of the vehicle. Remove the actuator. Have a buddy spin the right front wheel while you use a long punch or screwdriver to try to manually engage the diff. The left front wheel should spin in the other direction if the diff is good. Also before you check the diff you need to grab the front driveshaft and make sure it is locked, If it spins freely when the truck is in park and in 4wd with the front end raised then problem is in transfer case. If you can't make the diff engage manually with punch then the problem is in the diff. If front diff engages manually then the problem is the actuator. Hope this helps..

SOURCE: how to change 4 wd motor(actuator) 1997 s10

Before changing the actuator check the vacuum lines at the vacuum switch on the left side of the transer case if they are wet with transmission fluid the the switch is bad and that will prevent 4wd from engaging.

SOURCE: 4wd not engaging

Is it a two wire actuator or a three wire actuator? The two wire ones are pretty unreliable. that is why Chevrolet converter them to the three wire. Check for power and ground on the two wire in 4wd. For the three is should have one ground wire, one wire that is hot in 4wd, and one wire that is hot in 2wd.

If all the lights are out then the 4wd switch is bad but,if it won't come out of 4wd-low then the 4wd actuator is bad or stuck.The 4wd actuator is what engages the differential from 2wd to 4wd.HOPE THIS HELPS!!!

2005 Trailblazer XT won\'t go into 4WD. Front hubs don\'t engage with switch in cab. It will gear down to 4wd Lo but front wheels won\'t engage. Please help. Can\'t afford the dealer!

i've been told it was the 4wd actuator located on the passenger side near were the cv joint goes in to the front axle a good test is to floor jack it up so both wheels are off the ground and have someone on the other side , put in nutrual turn both wheels one way at same time and the 4wd drive shaft should turn if not its your actuator, costs about $86 for anew actuator and takes about 5 mins to change once you have the tire off

I have a 2002 Chevy Tahoe making a grinding noise in the front drivers side wheel, what could this possibly be?

If 4wd Tahoe, it is the CV joint going out or is out, replace part about 250 bucks, very common in 4wd Tahoe

4x4 went out

My 95 Tahoe 4WD went out. I was the front axle engaging piston located on the front differential. The front driveshaft has power but shifting into 4WD causes the front differential to engage the two front wheels. You can remove it but leave it wired and see if it moves. I'm suspecting yours may be similar. If that's the problem less than $100 to replace yourself.

95 tahoe four wheel drive stopped working/shift light not working

I have a 1996 tahoe that did the same thing to me.

There is no vacuum lines, it is all electric. The motor on the front differental is controled by the actuator switch on the top of the trans case. The motor is controled by 3 wires. 1 is a ground and the other 2 are signal wires. When the truck is in 2wd, the motor will get 12volts to ground on 1 wire all the time to turn the motor out. When you put it in 4wd, the motor will get 12 volts to ground on both signal wire to turn the motor in.

Here is the point!! Check to make sure that none of those wires from the t-case switch to the motor are shorting out on something metal. In my case those wires came out of the wire loom(black tube) and rubed the insulation off. shorting on the t-case.

If your truck ever gets stuck in 4wd, were you have to keep it in 4wd or the front end makes a hell of a noise, the actuator switch on the t-case is none to go out. cheap fix. If that ever happens and you are in a pinch. Unscrew the motor out of the front end and manualy give the motor the signals that it needs with jumper wires and the trucks battery to turn the motor out, screw the motor back in. Don't put the wires back on till you can fix it right.
