HELP!!! NO 4WD!!
ok, i have a 94 k1500 5.7 tbi with a 2.5 skyjacker and 33x1250 general grabber mts. my bro in law just put some 285 swamper trxus mts on his 92 3/4 ton with a 6.5L diesel and he had been wanting to hook our trucks up because he thought he could pull me. anyways yesterday i finally got tired of his mouth and we hooked em up in my driveway. we both his the gas and neither of us moved an inch, we just dug straight down about a foot. anyways the 4wd worked fine then, but after we unhooked em my 4wd was gone, i could barely get out of the holes i dug. i just put a new electric actuator in it 2 weeks ago. the light was coming on in the floorboard but no 4wd. today we unhooked the actuator and let it hang down while i engaged the 4wd, and the actuator works fine. so what do i need to look for here, i want my 4wd back and im scared this time it isnt gonna be as cheap to fix. any help is greatly appreciated, thanks in advance.
