my 4wd dont work and im thinking its the front axle actuator, how hard is it to get to and would it be fine just zip tying it open to lock the front axle?

 

We need information on your truck: Year, how many buttons on the switch or is it a lever on the floor. Stuff like that.

Now what makes you think that it is the actuator?

 

he said it all, Aanenson.

if it has a push button system, it could be any # of things. like the TCCM (usually the main issue), encoder motor, wiring.

with either system it could also be the vacuum switch on the t-case.



your lack of info makes it impossible to help properly diagnose the root to your problem.

 

its a 2001 4 door 4.3 liter, ive replaced the actuator at the transfercase, and the buttons do work (2 hi 4 hi 4 lo and auto 4wd) i know that, cause its gone in to 4wd a couple of times and now its not going in at all, the service 4wd light is on and comes on about 10 mins after i start driving it, i was just wondering if it would be ok to zip tie the actuator open to lock the front axle, and thanks for pointing out the problems i made on here, im still getting used to it.

 

If the service 4WD light is on, it isn't the actuator. For that light to be tripped, it is probably the TCCM or something else, but in that case, it is not the actuator

 

ok thanks! ill look into that, how much would it be to replace one?

 

my tccm went and i had no service 4wd light, just sayin'

 

thanks for stating that it's a 4-buttom system. it's another key point in diagnosis.

have you checked all of the wiring @ the plugs (inside & under the trck)? along the length of them for any wear?

question. is this something that is new (the 4WD not working) or was it present when you bought the truck?

 

weve had 4wd problems before but it was the acuator at the transfer case, it was a hand-me-down from my dad, i have not had a chance to look at the buttons yet, but if the lights on it should be in working order right?

 

there is no actuator @ the t-case, it's called an encoder motor.

there's a sticky on how to diagnose the switch, to see if indeed that is what the problem is..


now where is that sticky.........................

you can look HERE to start. look through the transmission section and you see what you're after.
