Does the factory '94 land cruiser actually have a locking differential. the dash light indicators says it 'locks' in four low but it sometimes feels like it slips? is it limited slip?
91-97 Land Cruisers had a factory option for front and rear locking differentials. This is a seperate switch and is usually located to the left of US model Land Cruisers. The center dash button locks your transfer case differential changing your Land Cruiser from all wheel drive to four wheel drive depending if you have ABS or not this button either says ECT or Center Dif Lock. If you do not have the Front/Rear locking differential option then your Land Cruiser has open Front and Rear. Hope this answers your question.
The ECT button has nothing to to with differential locks in either the center or axles. It switches modes in the transmission (ECT = Electronically Controlled Transmission). The "PWR" mode shifts later, letting you get the RPM up higher.
The stock US model 94 Land Cruiser does not have the center dash diff-lock switch - only 91 and 92 models did. Your center diff lock is locked in low range and unlocked in high range. You can buy a factory toyota switch and modify your wiring harness to change this behavior (search for "pin 7 mod" on ih8mud.com)
