Fishinguy40 Posted February 3, 2014 Share Posted February 3, 2014 Saturday I put the truck in Auto 4WD, as some of the streets and my daughter's driveway still had snow. As I left the subdivision where my daughter lives there was a couple loud clunks. It felt like the 4WD engaging/disengaging. When I looked down at the 4WD button it was in 2HI. I am positive I left it in Auto 4WD. Truck seemed okay rest of the day.This morning on my way to work, truck was still in 2HI (per the indicator light). I made a left turn on dry pavement and it sure felt like it was in 4WD. I switched from 2HI to Auto 4WD back and forth a couple times and it seemed to function (per the lights on the buttons) but I could never really tell if it was or was not. I am concerned because the clunks on Saturday were loud. You could hear them and feel them. There were no flashing lights or anything on the dash or 4WD button. I know that these 4WD buttons can be the cause of issues. Any thoughts? Quote Link to comment Share on other sites More sharing options...
Stcloudangler Posted February 18, 2014 Share Posted February 18, 2014 I have the same model as you, and had to replace the actuator chip in the transfer case. It got stuck in 4 low and the switch went out. A common problem, I was told. He also said that the auto 4wd feature was something to avoid. It puts added stress on the transfer case, just use 4 hi and 2 hi. Quote Link to comment Share on other sites More sharing options...
