Having problems with your 2000 Jeep Grand Cherokee ?
When i engage in 4 wheel drive,the jeep jerks when i turn and i hear a cracking noise,can it be my bad rotors an brakes?
I think what you are hearing is the CV joints complaining about the Differential being locked. Check to see if the Diff lock lamp is on or if the button has been pressed. When you trun a corner, the wheel on the outside of the turn has to travel further then the inner wheel, because of this, the outer wheel rotates faster and this is made possible by the differential. If the differential is locked then usually the inner wheel has to skip along or the CV joints start to jump over the balls (which is NOT good) Locking the differential means that the gears that allow one wheel to rotate faster then the other one are locked together and the wheels MUST turn together. This prevents loss of drive through the differential as it forces both wheels to rotate together, handy if you get bogged or are driving over sand or soft ground. But not recommended if you are driving on sealed roads..
