4 wheel drive issue
2005 Chevy Silverado 5.3FF AT w/ manual 4 wheel.
Shifting into and out of 4 wheel drive is smooth, but when
in 4 wheel the truck seems resistive and there is a whirring
sound. Shift out of 4 wheel drive and the transfer case
seems stuck even though shifter is back to 2WD. After a
few minutes there is a clunk and a bump when the
transfer case finally disengages. Thoughts? Thanks.
