How do remove the axle out of my 1988 suzuki samurai?

pull drum off and get an axle puller. Although correct this answer assumes you mean the rear axle. If that is the case pull the drum off after removing the wheel and remove four bolts holding the axle bearing to the differential housing (on opposite side of brake backing plate) and then use a reversible hammer (axle puller) to pull the axle out from the differential axle housing.
