Why doesnt the rav or highlander have a t-case? Because they are unibody, front wheel drive, car chassis with a transversely mounted engine. No room for a t-case really.

Reason why a tracker has a t-case is because it has a regular truck body mouted on a frame, rear wheel drive, with a longitudinally mounted engine.
