It was the TRD package that had the locking differential which was electronically actuated, right? But that’s entirely separate from the “true” 4x4 with the barrel drive shaft synchronizing the front and year diffs. Did you have a pre-runner? Some of those were sold with funky combinations that have the locking diff but a crippled 4x4 that disengages when you hit 10 mph.
