[nanyiru]

Hi there, im from mexico city (sorry about my bad english) ,i have a 1996 4x4 explorer, the transfr case and the tranny where replaced, and every thing works very good, the problem is when i engage the 4wd (high or low) the front wheels steel like a 2wd , every thing works great (driveshaft to front axle, the transfercase and tranny ) i guess the problem is the lock hubs or something like that.

I really need some help guys so if you suspec something just let me know, and if you got some pics or diagrams about the solution i´ll really apreciate it
