4wd problems
I have a 2006 GMC Sierra 1500 with 141k on it. About 10 days ago I was headed to work on icy roads, so I decided to put it in 4 hi. I first noticed that there was a terrible howling noise after 20mph ( I know it's not uncommon for there to be some noise like this, but this was terribly loud). Then I realized that even though it was showing 4x4, my front wheels weren't spinning. I replaced the front actuator on the transfer case, I can hear the transfer case engage but my front wheels dont spin in high or low. I have the auto 4 option, and the 4wd works when in that option, but I'm just perplexed why it wouldnt engage in his or low but it will in auto. Any suggestions?
