The 4x4 solenoid went on my 97 3rz. I had to switch vac lines in order to engage. Searched everywhere for the solenoid and could only find complete assy ($618). So I ended up grabbing one off a totaled 95 w/ man locking hubs hoping it would work. Turns out the part is interchangeable and it works perfect. Only cost me $9. Sure most of y'all already knew this but I was clueless.
