Ford Repair: 02 ford explorer, v6, auto 4wd, power steering fluid, differential fluid

Question
I puchased this vehicle used last November. After the vehicle is warmed up making a left or right hand turn, from a stop, on pavement, the vehicle shudders.  I have changed the transmission and transfer case oils. What do I need to do?  I think I need to change the rear differential fluid.

Answer
hey there, i highly dought that any kind of oil is going to cause your problem, there are two things i can think of of the top of my head right, try turning the wheel at a comlete stop, from lock to lock, if there is a shudder then, then it must be in the power steering system, possible a lose hose or bad power steering fluid, beleive it or not.   Or the second this is that the 4/4 is not disengaing. i beleive they run on " air hub locks" so the that system will have to be tested for proper operation.
