Here's a usable vid and some notes for the lower leg service:

__________________________
PREP
•Need a good quality syringe (rubber sealed plunger) for putting in oil. Small diameter hose.
•Not necessary to remove fork or clamp bike in stand. Hang by saddle when removing lowers, flip bike over when putting in oil.
•Remove brake caliper and secure it as far away as possible. Small amounts of oil will get everywhere.
•Wear glasses, oil can spray out under residual pressure. Even with valve core removed.
______________________________
REMOVAL
•Do not remove any bolts completely at first. Tap both bottom bolts first. (Gently, with plastic hammer).
•Clean inside of lowers with dowel and rag, there's dirt in there. Special attention to channel behind foam rings. Take some time.
•Replace old foam rings with new ones. They're cheap. Old rings swell when cleaned and tend to not reinstall perfectly.
(YMMV. Rockshox foam rings are available in bulk and cost less than <$2 a change. Fox rings come in a $30 kit, so maybe try and make do with alcohol on those gold nuggets).

REASSEMBLY
•Reassemby checklist: Travel indicator O ring on stanchion, foam rings installed, Slick Honey on seal.
Remove seal springs, slide lowers on, reinstall springs.
•Slide lowers all the way on, then back 1 cm to leave space for oil.
•10ml 0W30 each side. (Or whatever your fork specific requires).
•Don't fully compress (till bottom out) fork before reinstalling bolts.
•Torque bolts to 7.3Nm. (Rebound torque is 1.1Nm).
