killcrap, how do you manually put the necessary 330 foot pounds of torque on the axle nut? I've found it difficult to get much above 200 foot pounds without some serious air tools...

amacman, my loebro inner boot seems to be a less flexible blend of rubber/plastic than the outer boot but it is still quite pliable. Flexibility is not as important with the inner boot because it isn't twisted when turning the wheel like the outer boot.
