Q: Diffference between driver side and passanger side cv axle - 2001 ford escort zx2?

The drivers side axle will have a male end on the CV joint with a retainer clip that goes into the transaxle. The passenger side has a female end on the inner CV joint. Both axles outer CV joints have male ends. In order to remove the passenger side axle you will need to remove the three center axle bearing support shaft and remove the entire axle and inner shaft. Separate the inner shaft and the inner CV joint by clamping the inner shaft in a vice and driving off inner CV joint. You can then install the new CV axle to the inner shaft and reinstall complete axle into the vehicle and secure three carrier bearing bolts. Just a note to only remove one axle at a time from the transaxle or damage internal to transaxle carrier bearings.
