3/16" pin punch or 3/16" roll pin punch is needed to drive out the roll pin. Finding a long pin punch is a ****er these days, same on the long roll pin punch. If you can't find one, grab a 2" long piece of 3/16" tool steel from a machinist, and use it as a punch extension. It's hillbilly, but it's all I use for now. Use the roll-pin punch to drive until it bottoms, then use the extension. It's better then the $30 Snap On wants for a long roll pin punch.
Best way is to pull your shafts, you shouldn't have c-clips in a Dana 44 axle. Then mark your bearing caps, remove bearing caps, and pull out the carrier. Drive out the roll pin, drive out the cross pin. Rotate the spiders together, and remove spiders. Remove sidegears. Wash and inspect sidegears, spiders, and all 4 thrust washers.
Replace *****ed parts as needed, lube with new 80W90. Installation is reverse of removal. Torque bearing caps with blue loc-tite.
