What information are you looking for?
Ok someone will be with you shortly.
This truck is equipped with a TRS sport package which includes a limited slip rear differential. The gear ratio is 3.727
also you need to know that there is an open recall that number is ***** which is inspection and/or replacement of the rear leaf springs. You need contact your local dealer to have that recall taking care of.
41110-35A70 Is the Rear Diff number. Sorry to hear the dealer is giving you such a hard time it's really not that complicated the look this information up.
41110-35A20 is the part number for the 3.727 diff with the locker mechanism. Theoretically yes this could be done. However it would be extremely difficult to get the locker to engage the proper depth and timing because of the limit switches that are designed into the locker motor. The 4WD ECU controls the engagement of the locking differential and even then it will only allow it up to about 20 mph on the factory configuration. Without knowing what the limit switches are doing and timing it correctly it will be difficult to just put in an on off switch and reverse the polarity to engage the mechanism and disengage it. The limited slip differential will do just about the same thing and a lot less aggravation.
