It seems like it would be cheaper to find a transfercase on ebay with the sensors attached and replace them from there. Look for trooper/rodeo/axiom transfer cases and see if the part numbers on the speed sensors match, maybe call Merlin at St. Charles isuzu and ask if you can use the trooper/rodeo/axiom ones on the VX? Those sensors going bad seems like a once in a lifetime deal
What does the 5 hour labor entail?
Welcome to my world and some people think we ask too much? See what you have to pay for one little item. I suggest just purchase from any salvage VX. If we has we would sell to you but we have decided to bring our parts one back from the grave.
