Mercedes Man,

Tapered roller bearings should be snug without any play, when you rock the bearing with the road wheel attached.

The reason your jeep, or other cars with similar bearings spin longer is probably due to the fact they don't have this ultra cool nut to tighten the bearing. On other cars you have to choose a hole for the cotter pin, and it always is a compromise as to pre load on the bearing.

Hope this makes sense...
