I have noticed that on the rear axle some have the wheel bearing's inner seal removed, others run with the bearing "sealed".
Anyone have any thoughts?

Adger,

Sealed axle bearings are used in many applications. FWD cars and late model cars with struts have sealed bearings that last for a long time. Non sealed bearings require additional lubrication just like in rear axles. What I have done in the past with sealed bearings is to pop out the seals, wash out the grease and replace the the original grease with a high end synthetic grease and put back the seals.
