Inspect the bearing (this one is obviously toast!)
The inner part of the bearing should spin freely and smooth. They are fairly inexpensive to replace, so use your judgement whether to clean and reuse or replace.
Reinstallation is the reverse order of removal.
Clean and inspect the frame where the bearing goes, and lightly oil the machined area before reinstalling the bearing. This is also the best time to re-grease your upper stem bushing.
how tight do u tighten the lower stem nut do u go tight to bearing or keep it loose and just let the safety wire hold it on
just a little past snug is how i tighten mine. I'm sure there are torque specs that you can find on it but i have never had any problems using the german method of good-n-tight
