The 175MM FIA (Front Independent Aluminum) is an independent assembly with an aluminum housing and cast iron differential. The 175MM FIA uses an open differential which is supported by two tapered roller bearings located on either side of the case. Differential bearing preload and ring gear backlash are controlled with select shims located on the outside of the differential bearing cups. Pinion height is set with a select shim sandwiched between the pinion housing assembly and the axle housing.
