I had this happen on my 97 Jimmy. Somebody on here (Davo I think) told me to disconnect my battery for a few minutes. Then hook it back up. It's worked great every sense. Good Luck!

Possible front axle actuator

Hi Kenny,

The front axle came from the factory with a gas filled actuator. There is a bulletin issued in 1998 (#76-43-01) on this from G.M. They have addressed the problem with a new type of actuator it is no longer gas filled, it is now electric. You need to install a new harness and actuator this will allow the front axle to engage immediately. No more waiting for the gas to expand and engage the front axle. Time to complete the repair about 1 hour.
