Vibration when turning.

[theIrish]

My girlfriends 91 ford explorer vibrates or almost feels like a chug when she turns to a sharp left. This only seems to happen when she has on her 4wd. Does anyone know what this could be? If so does anyone know how much this is going to cost me to fix? Besides that the Explorer drives good but the alignment is off a little. It drifts to the right.

...i would be guessing but it might be your spindle nut has come loose and maybe a bearing problem...since you say it pulls to the right, check that side...here's alink to look at...i hope it helps..
