Check the actuator that locks in the front hubs this is probably the problem i had the same thing happen to my truck.

More than likely it is the actuator that locks the front hubs in to four-wheel drive i would check that first.

On my 01 grand vitara i changed the 4wd pump behind the bumper the indicator light for 4wd now comes on but 4wd still does not engage


what does engage mean.? it fails on ICE or DIRT

engaged, means, (mechanically) one tire front and rear have traction

with LSD front and rear all 4 have traction and spin on ice

does it?

part time 4wd dont work on dry pavement so that is my 1st question

why not state, what you are driving on, and what does engage means

by what means did you check engaged.????



this car is not AWD, do you know the difference from AWD and

Part time 4wd? the diff, is there is center differential. on part time

so must be (true test) tested on ice, or dirt.



see the videos here, or a demo.

or on ice. ice you will see front and rear both working,

on dry plave ment all you get is windup... very very bad to do

in traffic, causing you to wreck and other to get , hurt.

if you understand all that, then do say what you mean

ENGAGED.

if you know what windup is and it dont, then you are correct

its not engaged. (jack left front tire up, engage it and feel it? by turning the the tire, it must fight you)

front up, rear down. in 4wd.

here it it is again.

http://www.fixkick.com/part-time-test.html



if it dont engage for real,. may i introduce you to the FSM

its in my hand now.

page 3B-3 . see it?

switch closes in xfr case

ECU sees that and powers up the air pump.

if pressure is good the Ecu is told that, if wrong you get scanned DTC code saying just that (obd2 scan too)

the pump has 2 shut off modes, good pressure. and fails to hold for 10seconds. (prevents pump from running all time)

if all the above works the Lamp glow by PCM command.

if you have full pressure , the lock in the front axle is now locked

no pressure, no lock yes full pressure it must lock or the axle

actuator is bad.

the page 3B6 says pressure is 4.25 to 6.40

page 3b10 is the acutator test. and the TRUE ENGAGE TEST

front wheels off ground.

apply 4.2psi with shop air and reg.at the acutator nipple

1: you spin one tire, the other spins backwards (GOOD test)

kill the 4.2 psi supply air

2: you spin one tire.

and the other tire, does nothing, (remains stationary)

pass. test 2.



test one is locked

test 2 is 2wd.



the other tests are on ice or dirt.

does that help?

4wd not engaging. Check actuator and seems to working properly. Jacked front end up and and when in 4wd the front tires spin freely. Any suggestions?


Does the driveshaft for the front wheels turn when in 4wd? The actuater might work but the diff lock for the front wheels might have broken. If the front driveshaft does not turn when in 4wd, the transfer case might be the problem.

Check the oil in the transfer case. If it has lots of metal in it... time for a new one. They aren't the world's strongest.
Another check: Lift the front of the truck, while keeping the rear wheels on the ground. Engage the 4x4 switch (then turn the truck off) crawl under and try to turn the front driveshaft by hand. If it turns and the wheels turn, the transfer case is the problem if it turns but the front wheels don't... front diff issues. Any grinding, crunching etc is also a clue.

Four wheel drive actuator


I would try taking the right tire and cv axle off there next to the oil pan is a part that the axle slides through.it has a connector that engages the axle or 4x4 but if it is dry it will need to be replaced or checked out.it is kind of hard to take all of that off but check it out

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

Noise in front end 2002 zr2 blazer


Two things maybe your problem:1 .Front axle actuator to engage 4wd is not releasing. 2. Front axle u-joint needs replacing. Lift car on jacks with front end off ground. Then spin tires by hand as fast as you can and see if you hear the noise and where it is coming from ( spin in both directions).

4wd won't work axles turn electronic box engages front tires won't lock in


have you checked to ensure that the actuator is working? if the actuator isn't working then the ring gear wont engage and won't turn the front shafts. try turning your key to accessory and put the truck in 4wd
