Thanks in advance,

THERE IS AN ACTUATOR ON THE FRONT AXLE AN ONE ON THE TRANSFER CASE, THE ONE ON THE TRANSFER CASE LOCKS THE DRIVE SHAFT IN AND OUT OF 4 HI & 4 LOW. THE ACTUATOR ON THE FRONT AXLE LOCKS THE FRONT DRIVE SHAFT IN.
Don't be afraid you will lose grease, it will only drop out a few drops.
IF the actuator is working, it can be the front gears.
lots of luck
I'm new to the forums but I've been reading them for a few days doing a bit of research. I've got a 2003 Silverado 1500 with the electronic switch on the instrument panel to engage the 4 wheel drive. I'm noticing what I would call a grinding noise coming from the drivers side front when I activate either the auto 4WD or 4 hi. Its very noticeable when I make the switch on the move and will persist until I switch back to 2DW. I could not hear it when I engaged the 4WD and drove in reverse up my driveway...its a pretty long driveway so I think I would have heard it but I can't be sure.
From other posts on the board concerning similar problems, I'm leaning in the direction of the wheel bearing on that side but I wanted to pick a few brains here to be sure.
Thanks,
Ken
Could also be a u joint in front drive shaft
I have read thru all of the relevant post in this section and I haven't read anything about the problem I am having.
I was cruising down the freeway at about 65-70mph in 4Hi and I noticed what I can best describe as a clunk from under the truck. It was very intermittent and disappeared when I switched to 2Hi. I had a jeep several years ago and I remember what it feels like when the chain is slipping over the gears....this feels very similar. I checked the fluid and found it was low. I filled the case and went for a test drive. I now noticed the same problem only under acceleration at speeds above 10-15mph. At this point I figure the chain has stretched due to lack of oil.
Yesterday afternoon I tried the 4Hi again and notice there is now no problems, no "clunk" or what feels to be chain slippage. I drove it around for several hours without issues. I drive into work this morning and it does it starts doing it again. I went out for lunch and tried again...this time when I press the 4Hi button I hear a grinding noise under the truck. I am thinking maybe the 4 wheel drive is not engaging fully?? Could a bad encoder on the transfer case be my entire problem? Maybe multiple problems? Any help would be great!
Thanks,
Mike
I tried the 4Lo position and I am having no problems at all. In 4Hi, it mostly makes grinding noises in forwards and reverse. I am leaning towards the TC motor.

Drained the oil and there is no metal.
Is it possible the actuator stuck?
I have a 1995 chevy Silverado 4X4 with the same problem, I was wonderring if you could tell me where you found the shcok mount from the dealer for $102.88
Thanks

go by the tag on the rear of transfer case.
I am from GM Customer Service. Did you take the vehicle back to the dealership and have them look at it again? What is the VIN of the vehicle? Is the vehicle still under warranty? Thank you,
Mariah GM Customer Service

I apologize that you are experiencing a concern with your vehicle. Have you had a dealership look at your vehicle and try to diagnose the concern? Thank you,
Mariah GM Customer Service
I replaced it with a new fuse and it blew as soon as I pressed the button. Any suggestions? I sure would appreciate some help.
I dont know who checked it for you , but they have to have years of experance to perform this test.
If you are not confident in the person that performed the test , then have some one else to check it.
Lots of luck.
