Gmc Binding When Taking Sharp Turns

Hello.
I Have A 1999 Awd Gmc Safari. When It Is Warmed Up And You Take Sharp Turns It Feels Like It Is Binding. It Usually Will Not Do This When You First Start Off Your Day But Within A Short Time It Starts. It Seems To Get Worst. I Have Brought It To The Mechanics And They Have It..it Is The Serpentine Belt Or This Is How Awd Are. This Is My Second And My First Never Did This. It Is Scaring Me And I Feel Unsafe In This Vehicle. Anyone Have Any Idea What The Heck It Might Be. Or Do You Have The Same Problemw Ith Yours

Mine (a 95 safari and hence not awd) did that right before a number of other problems arose. I think it was a fuel delivery issue. I got stuck in a turn when it died one time and now my wife does not feel safe in it. I'll let you know when the problem is over with, so far I have replaced fuel filter, sending unit and pump/wiring harness. Still dies when I get on it or turn for any length of time.
