2005 Chevy Silverado LS 5.3FF AT w/ manual 4WD: shifting into 4WD is smooth, but transfer case seems to whine and when you shift back to 2WD it shifts smooth but seems like the transfer case doesn’t disengage right away. When it does there is a clunk/bump. Thoughts?
Also, I don’t use 4WD much, just in the winter when the roads are slick and the 400lbs of sand in the back of the truck don’t cut the mustard, and at that just to take off from a stop or to pull someone out of the snow bank. Thanks.
