Clois - I've threaten'd to cut them myself down through the years, but never done it, always sent them out. Of couse if you do that it assumes you have enough spline lenth on the ends to just chop em off. To continue RE; the original post, the wheel bearing itself has a exterior
oil seal and it is all you will need on a street car regarding a dust shield. That is of course unless you are going off roading into rivers. If it were me I'd also lose the housing axle
oil seals forever too, let the housing
oil get freely to the wheel bearings. This could help your wheel bearings with mild road race work. The backside of this is later the seal could get weak and and you could possibly get a leak that would oil down your prized mag wheels.Your call. Another thing, this might also be a good time to weld up a oil drain bung on/to the housing if it does not have one. And I can't stress enough,,,,,, make sure the housing vent is clear and open. Good Luck........
