this was my first time doing this and thus a great learning experience.
i discovered that driving the inner bearing seal (2wd front rotor) was much trickier than i thought. i do not have a bearing driver or a large diameter socket so i used a square block of wood. no matter how square i tried to hit the block or how careful i was i could not prevent the seal from starting crooked and ultimately seating with a slight ripple. i went through 4 seals before i finally got it right by using this method....
i cut 3 strands of solid copper wire, enough to go around the perimeter or the seal.
12 gauge with the skin
14 gauge with the skin
14 gauge bare
starting with the larger wire and working down, driving each to it's limit with the wood block, the wire acted as a guide to prevent the seal from tilting, driving it down even in small increments. by the time i was finished with the 14 gauge bare it just took one good hit to finish driving the seal to it's even seated position.
worked great
