new wheel bearing STILL CLICKING?

[dmartin1]

driver side front wheel began clicking on my 82 stepside. i jacked the truck up spun the wheel no clicking. no play back and forth bearing was tight and good.

no clicking while turning and moving either.just straight and it would go up and down faster and slower i went in the truck.

i pulled the wheel and took it all apart. it has newer timken bearings and races all greased well.
i tapped the old races out and installed new with new timken bearings that are ridiculously packed with grease.
reinstalled everything, about 50 miles later its clicking AGAIN.same thing.

did i not tighten the nut that holds the spindle/hub on tight enough?
i tightened it until it started to grab then backed off barely a hair to get the cotter pin in. is this wrong?

any help will be appreciated
