92 cherokee possible flywheel noise?

when regularly driving seems to be no problem with vehicle, but when hitting a bump (especially speed bumbs, even at very slow speed), there is a metalic skreach, (simialar to belt slipping) it has fairly new belt and just replaced an idler pully (because thought this could be the problem, but no.) it seems to be worse when starting out driving then lessens thru the day. it also happened once when starting the car in park. ck’d all pulleys, no rub marks anywhere, not shock problem,(all new on all four wheels). am thinking possible flywheel or clutch problems? any suggestions appriciated thanks very much for your time. 4.0 liter with auto trans.
