While driving,taking off is fine but when I let off the gas then give it the gas again,I here a clunking noise like there is slop in the trans or Diff.or transfer case or something.any ideas what could causing this?
Yeah, slop in the trans or diff or axles or transfer case. Could be engine mounts, too.
Or worn universal joints in the driveshaft.
I’d say possibly loose bolts or crack on flywheel/ flexplate, also had a ford Taurus that did the same but turned out to be broken baffles in gas tank, the banging sound was just the sound of gasoline bouncing around the tank
