Replacing input flange seal on diff for BMW F3x.

Perfectly video for input flange seal 👍

Cool, one thing I didn’t do in this video is mark the set nut/input flange. Make sure you do that, that nut is was sets the backlash on the diff

I have slight play on this shaft and vibrations at 120 km/h. Is it safe to tighten it slightly? Few mils.

I would not tighten the input nut anymore than it supposed to be. If you tighten it more it will change your backlash/wear pattern and ruin the diff.
