Remove rear axles 99 montero sport - 1999 Mitsubishi Montero Sport

This is like every other rear axle they are all built close to the same, you need to pull the wheels, remove the pumkin housing in the center of the axle, inside you will find 2 ring gears with a shaft that goes from top to bottom, on one end there is a cross bolt remove it, then the shaft will slide out and the gears can be removed, not push one axle at a time twords the middle, you will find a horseshoe clip on the end
remove it and that alxe will slide out the end
repeat on the other side, and there you go axles out...
