1995 Chevy 2500 4x4 Not Working

Unread post by chevydiesel » Thu Sep 09, 2010 3:37 pm

I have a 95 2500 silverado and the 4 wheel drive stopped working. I replaced the actuator and checked wires and all was fine. The transfer case engaged and the drive shaft was spinning, but no front wheel movement.
Now today I heard some grinding coming from the front axle when I was driving to work (not in 4 wheel drive)
but it didn't last long. What could the problem be? Thanks.

If the drive shaft is turning but the wheels are not, then you have a front differntial internal problem. This would also explain the grinding.

You can check the fluid in the front differential, and if there is none, or if it metal colored you know you have a problem internally. If you replaced the actuator, you could have mis-aligned it while reinstalling and that would cause grinding while it is trying to engage and no 4WD.
