Take your old seal to NAPA or O'Reilly and match it up with a good National

new seals. After you set the play and put the cotter pin in, install the zirt and
pump grease until it comes out. Then hand pack the Vault cap and tap it on.
Done! Use any good wheel bearing grease. I use red n' tacky. Advantage of
regular grease is, if you lose a seal, you will still be able to limp in without losing
ALL your lube.
