Just bought an 05 LLY 4x4, had pump rub evidence on the t-case but was repaired and no major damage inside. Was working great in 4x4 but then yesterday pulling a trailer through my field, moving easily no crazy spinning or anything it felt like something bound up and I heard a load pop. No noise at all in 2x4 but when in 4x4 now it pops every couple turns of the driveshaft and shakes the whole truck, feel like something's binding and letting go but it never stops pulling the front wheels, any ideas or similar issues anyone has had? I'm thinking its the front diff but not sure yet
