Jeepcruizerph,
Yoli's LC90 is powered by the 3.4 V6 engine. But the manual should contain all information pertaining to the LC90 (even the optional equipment). Different models have different 4x4 systems. Local LC90's used a part-time system manual locking hubs. Yoli's Mid-East spec version uses a fulltime system with a locking center differential.

I will just PM you regarding the manual ASAP.

What I have at home right now is an LC80 manual. I don't know where the hell it came from. Hehehe. I think it came with our LC77.
