is the a site that can give me help with my 4 wheel drive truck. I have
replace the sensors and was told that it was an actuator. I see that it is
busted and need help locating the part on a diagram. I am looking on a site
with gm parts but don't see it on the diagram. Any help would be
appreciated.

If you are talking about the electric actuator that goes on the front
Axle, there are aftermarket companies that make these like Rancho
Suspension.

The factory stock part is said to be crap, as I believe it works by heat
melting a wax ball, or something like that inside the actuator, and in
cold weather conditions, the switch to 4x4 is not instantaneous. I
believe the Rancho Actuator works mechanically when voltage is applied
to it.
Hope this helps, Mark

Around 97 GM changed to a motor driven one and it will retrofit on the
older ones

I see Snoman. Thank you for the clarification.
I don't know much about these, but remember reading something to this
effect. Mark
