O.K. I'll try that first but untill then I have one more question for you. I'm sitting here at the computer while I am rebuilding my surpass 91 which ate the rear bearing. Question is when I put these bearings back in should I use both the seals supplied with bearings one or none. May be a dumb question but I'm wondering about lubrication. And by the way, what did we do befor we could ask these questions of all of the experts on the Universe?
