My 1994 vintage Shorelander trailer uses an odd grease seal with an ID or 1.75 as opposed to the standard 1.719. I suspect this is due to the stainless replaceable wear sleeve on the spindle's seal surface. Could I use a standard seal in a pinch if I removed the wear sleeve? I sthe sleeve that important? I tend to check the bearings every year and run no more than 1000 miles/yr. I have to order the seals as no one stocks then near me.
