    4wd not working. AUTO 4wd works

    I agree that locker/limited slip G80 should of grabbed. I jacked up the rear and spun the wheel with my hands and that bad boy locked up. Not sure if it is warm and doesn’t operate under heavy load. Not sure if the G80 needs rebuilding at some time. Thanks friend. :-)

    4wd not working. AUTO 4wd works

    I am seriously thinking about replacing the entire encoder motor like you did Rather than paying for the computer checker. It just seems like that is the problem. And the cost of it doesn’t break the bank. Worst case I would have paid for a new encoder motor for nothing

    The part you spoke of last is not in the encoder motor correct that is the part that the encoder motor turns inside to transfer case I believe is that right

    4wd not working. AUTO 4wd works

    Thanks for that. Sounds like same situation mine has. So you only had to replace encoder motor. That sounds cheaper than cracking the Transfer case open. I do need to find someone with a Tech 2

    4wd not working. AUTO 4wd works

    I think I hear both actuators. I am not sure how to turn off the traction control. Sorry. I took her to Chevy Dealer who told me I needed a new transfer case $3,000 plus. I then took it to Cottman Transmission. They were really honest and didn’t know. I have not jacked it up myself and...

    4wd not working. AUTO 4wd works

    My 2 Wheel Dr and auto four-wheel-drive work fine. Thr 4low and 4hi do not work. I am on a flat level surface in neutral when I press the button and the indicator light indicates a good shift. No warning lights. I hear the actuator shift when I go into four low and four high and 2 Wheel Dr...
