Possible transfer case noise

[Douglas Friedberg]

So is the chain relied on even in 2 WD as well ??
Rear end was done awhile back.

Thanks for the info people.

The other thought I was thinking aware of this noise is it sounds similar to when you are moving in neutral at Agee mph when changing to 4 wheel drive manually.
Could this be Servo motor screwing up trying to change mode on its own? Only happens when you start to move forward ???

It will eventually rip through the case body and destroy it without prejudice. My wife's 2003 did that and I had to find a core and rebuild it. The infamous pump rub leaked all the fluid out over time and thats all she wrote.

I drained the transfer case oil and refilled it. Nothing seemed out of place.

Just like a bicycle chain derailer chain skipping the sprocket during gear changes on a bike. Yes jerking and slight hesitations then goes away. Doesn’t happen all the time. Domes traction code flashes on dash panel then goes away. Was afraid of this outcome. So there’s a chain in transfer case. Like old olds front wheel drive trans shit out of luck time i guess.
Bad part about 250,000 miles I guess.

I just read this, and your response today about the oil change. You may just have a malfunction in the traction control. Bad sensor for wheel or shaft speed.

Are you familiar with the feeling from traction control activation? It can cut engine power; use the ABS to apply brakes to individual wheels, and make a jerky feel in the vehicle, along with the attendant noises from the brakes and pump.

Yes something is going on there because along with this comes traction message and gas pedal not responding to foot control pressure. I think that seems to me pedal control is removed by system when it sences traction problems but this all happens only on take off or starting out from a stop.

Traction message only appears for a few seconds then goes away. I am not formilure with this computer system. Just old world 4 wheel drive. I tried pushing button on dash to disingage system to see if that helps but have not concurred results test Happens cold or hot doesn’t mstter

To my ears and feel it seems like system is in the middle of going between changes from 2 wheel and 4 wheel or thinks it’s on ice.

Other then that vehicle drives normally with no sounds of anything is wrong
