grabbing on acceleration
i have a 1999 expo 5.4l 4wd w/70110 miles and i am having a problem with it that i cant quite figure out
after about 10 to 12 mi crusing and i stop at a stop sign and take off again i am getting like a grabbing feel ( feels kind of like somthing is slipping ) then i will have a growling sound and cruise acceleration and a slight vibration ( speeding up , going up a slight up grade ) i have changed almost every part i can think of ( wheel bearings , brakes , rotors , brake lines , front and rear calipers , front diff fluid used mobile 1 80w90 syn, clutch fan , )
what do i look at next or should i just take it to my frindly ford dealer
thanks
