why do you have the upper rubber seal in the lower dust cap to C ?
here ya go order of install.
lower =
empty "c"
r=tin dust cover dome up . I like little rtv to seal it to "c"
race cone section down . press up in .
bearing
seal is stepped so bigger half will go flush or just inside the "c" .
lower pin once knuckle is on .
-------------------
upper is king pin 500-600ft lb spec
black rubber seal gm/dodge or ford
knuckle on / lower king pin in and floor jack to hold all up/tight
upper bushing . new there cheep or upgrade to bronze/ampco metal ones .
upper spring index washer then spring . or upgrade to crane off road spring eliminator kit . big urethane bushing and shims in kit ( if needed I didn't ) .
then gasket on top and arm /cap and bolt all down .
