I have a 2002 gmc sierra 4x4, the front wheels will not engage when I put it in 4wd. I have a 2 inch leveling kit on the front thats the only mod. The axles are fully engaged with the front end, and the actuater on the front is engaging when 4x4 is selected what could be wrong inside the front diff thats not letting it lock in? The front shaft spins when in 4x4 but the front will not lock in? Can the plunger on the front axle not be extending enough to lonck it in? HELP! Thanks, Mark
