I am new to community and would like to give my greetings to all of you. I have a 2006 Chevrolet Colorado Extended Cab 4x4 Z71. While in 4 wheel drive, you can steer fairly sharp to the left and the passenger side rear wheel will lock and scoot/slide the tire like the brake is engaged. When the 4 wheel drive is off, everything works as intended. I took the inspection plate off and the rear-end looked fine. I am uncertain as to what the issue is. Thank you for your help.
