To remove the front driveaxle, follow these steps: a) Loosen the wheel lug nuts and raise the vehicle on jackstands. b) Remove the wheel and the driveaxle/hub nut from the axle, then separate the lower control arm from the steering knuckle. c) Swing the knuckle/hub assembly out until the end of the driveaxle is free of the hub. If the driveaxle splines stick in the hub, tap on the end of the driveaxle with a plastic hammer. d) Support the outer end of the driveaxle with a piece of wire to avoid unnecessary strain on the inner CV joint. e) If removing the right driveaxle, carefully pry the inner CV joint off the intermediate shaft using a large screwdriver or prybar. If removing the left driveaxle, pry the inner CV joint out of the transaxle using a large screwdriver or prybar, being careful not to damage the differential seal. f) Support the CV joints and carefully remove the driveaxle from the vehicle.
