So. I hit a washed out road from flooding and bent the rear end. Had a spare parts truck took rear end off of there tried to drive high revs than shift i guess limp mode? I put a code reader on and said no signal from front tires and rear diff speed sensors. I dont even have speed sensors up front. I replaced rear diff one brand new i replaced the one on the tranny by transfer case with one off part truck still nothing. I need this truck as its a work truck. Any help thanks in advance.
