i heard chattering in rear lsd

ok so i did a couple of oil changes on my truck today.
5.5 qts of castrol syntec
new mobil 1 oil filter (m-209)
new afe pro dry s drop in air filter
and lastly a rear lsd oil change using castrol hypoy c (3 qts)80w90 w/ 7oz lsd additive.
I did my round abouts (8 turns left n right) and everything and didnt hear any grinding or chatter however when i had to floor the gas pedal for a lil bit the lsd chattered for a few secs and stoped when i eased off the pedal. when i got off the freeway i floored again to see if it would do it again but good thing it didnt. should i add a half tube more of lsd additive on the safe side or just let it go?

 

the bottle was a 7oz called tran x posi trac. the tube said pour the whole thing in. anyways, its been quiet since. i'll post if something goes up.
