2002 models have either a 198RBI or 8-1/4 rear
Differential, while 2003 and later models have the 8-1/4. Also, the 198RBI is identified by four bolts and an axle plate. To remove it, loosen the lug nuts, raise the vehicle, remove the brake drum, release the axle retaining plate, and use a slide hammer to pull the axle. Also, installation includes cleaning, driving in the new bearing, applying grease, and refilling the differential with lubricant.
