Review on Dorman 419 610 Idler Pulley by Marco Habersham

This pulley is the correct size 76mm for the upper left idler pulley on a 1997/1998 Grand Cherokee 4.0. The lower right idler pulley is technically an idler pulley and is slightly larger at 90mm and the Dorman part number for this pulley is 419-602. I'm not sure if the pulleys are the same size on the 93-96 Jeep Grand Cherokees because I know the 4.0 has changed quite a bit since those years, check to be sure.
