Ball Joint Torque????

Guys I'm replacing the upper control arm and balljoint in my 90 Civic sedan. Do you tightend the nut on the balljoint down tight and if the hole lines up with the castel nut, put the cotter key in or do you tighen it down and then back it off to the next place on the castle nut and then put the cotter pin in? I have totally forgotten. Thanks guys.

backing up crown nut is usually not that bad, as they have plenty of openings for cotter pin in it. now, considering that you have fine thread in the nut, it is very easy to strip it. so don't over crank it.

Thanks. Got it. :)
