Dang dude.... you might want to wait till you have somebody there that knows what they are doing to help you. Im not trying to be mean but the bearing caps are pretty basic, and other than taking off the diff cover its probably the most straight forward part of the install. To answer your question the bearing caps are part of what the carrier bearings ride on and what holds the carrier into the housing other than the axle shafts. The bearing caps are literally cut out of the housing after the housing is cast and machined for the bearings, so it is extreamly important that they go back on the same way they came out. There will be one of these on either side of the carrier, held on by two bolts per side. To do this install you will have to pull the axle shafts, take off the cover, take off the caps, remove the carrier, remove the cross shaft from the carrier, remove the ring gear, remove the spider gears, install the locker correctly, then put it all back together making sure you torque everything back to spec. Im sure there is somebody on this board that lives close enough to you that would be willing to lend you a hand. Check your local chapter, there are alot of good people on here!
