I called my local dealer yesterday as well. Parts guy says just running the VIN # tells him a lot of things but doesn't specifically say ya or na on LSD. But ... when the VIN # is entered and he goes into the part selection for LSD, it should either light up or not light up as a applicable part for that rig.

So what he's saying is, just having a dealer run a VIN # won't help you one bit! The combination of the VIN # and looking into their parts system for a specific part is the only way to determine if LSD was installed from the factory.

So, if any of us are trying to confirm whether a wrecking yard rig has LSD or not, call your local dealer. Ask for the Parts Mgr, have them run the VIN # on that particular rig then look up the rear Diff options to see if LSD lights up on their system.

Of course this is assuming all stealership parts systems are the same so good luck.
