Rear wheel bearings

Seeking peoples wisdom please.
Having recently had cause to remove a halfshaft from my '72 145 I am finding it difficult to understand the thinking behind the design of the outer bearings. I am familiar with the need for shims to adjust end-play on an Amazon axle, but there is no method of adjustment on the 145. When the halfshaft is installed the securing plate pushes against the outer oil seal which in turn pushes the inner part of the bearing(retained on the halfshaft) into the outer part(loose fit into the axle tube). The bearing is a taper roller bearing that usually requires a 'pre-load' like the side bearings of the differential, and as such any end-play will also create lateral play. Does the outer oil seal have the ability to deform under compression and retain a degree of force on the bearing to eliminate end-play? On the other hand, have I missed something?
