"Thanks for the kind words. The Internet is overflowing with videos on how to pack trailer bearings. My only advice is to buy high quality seals (Timkin or SKS)  from a bearing supply house, not the cheap @#$&amp;* Chinese ones from Pep Boys.

I can’t help here. \n  \n\nJohn Davies \n  \n\nSpokane WA \n"
