So. I hit a washed out road from flooding and bent the rear end. i have a spare parts truck its a 98 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 transmission by transfer case with one off part truck still nothing. I need this truck as its a work truck. Any help thanks in advance.

I replaced the wiring harness going back there to the tail light gas tank and speedo all one harness and i replaced the cluster already.

Replaced cluster and sensor on rear axle and one at tail end of transmission.
