So just got my truck back a few weeks back after it was stolen. Been running into issues from modifications made while the thief had it. First off the OBDII port is not working anymore. Been chasing that down, then found an aftermarket tuner half a$$ installed that killed the truck. New fuel pump and she’s back on the road. 100 miles later the rear end is out. Now trying to find out what it is exactly. Looks like it might have been swapped. “4.10 VYC35 BA V606263 2 LS.” Looks like a 4.10 LS but I cannot tell if it’s a Dana 80 or not. Cover is “DANA, 47717 1, 271 9, REV C, 04 23 98. The truck is a 2000 model. Going to need some help or I’ll be towing back to the shop again...... thanks.
