[Vwdiesel] Are the axle Shaft assemblies different ?

[Photo Bug]

Are the axle shafts on the Caddy diesel different from the axle shafts on the Rabbit diesel?  I replaced the left front wheel bearing, wheel still locks up.  I have another Caddy, starts hard in the winter, so I may use its axle shaft assembly on the right side, so I can have something to drive to school on Monday morning where I teach Math and talk a lot about the advantages of diesel powered vehicles in the spare moments.
 
Thanks!
