Answers :

On the front axle of your Suburban there is a thermally (an internal heater) activated devise that pushes on a lever to engage the axle. There is a technical service bulletin ( #76-43-01A) on this problem but the repair isn't cheap.It involves installing an updated devise with a DC motor from General Motors which also requires a new wire harness.
I have found that installing an aftermarket one (available at your local autoparts store) that just bolts on will work just as well.
It just threads in to a housing and is very easy to replace.
