4x4 K1500 Chevy Truck, 4 wheel drive repair instructions
There are a number of different hub systems so this may not work but it has worked for me on both auto and manual locking hubs. On a flat surface without traffic. Put the trans into neutral, shift the transfer case into 4x4, shift the trans into reverse and back the truck up 15-20 feet. Completely stop and shift trans into drive. See if this has locked the hubs in. If not, you can also try following the same instructions except shifting into 4wd low. Sometimes the hubs need a "bump" to get them to slip into place. Keep In mind that if the 4 wd low select works, you need to shift it back into 4 wd high before continuing! When taking the truck out of 4wd to 2wd, I recommend the same, shift to neutral, select 2wd, back truck up, shift back to drive and check. Its entirely possible that your hubs need maintenance (they're often overlooked) but hopefully this will get you going. Please let me know if thus worked or if I can offer other suggestions. Good luck!
