Hi all, I'm selling my 2000 limited and this happened. Potential buyer took it for a test drive, came back with it stuck in 4wd. I asked him what he did and his reply made me a bit upset. He said they pulled into parking lot, put truck in park, shifted into 4lo, put in drive and made several circles on pavement. He couldn't get it back into 2wd so just drove it the 2 miles back. I swear every drivetrain light on the dash was lit, and nothing I tried would get truck out of 4wd. What kind of damage could this idiot have done? Any ideas how to get 4wd freed up?
