squeaky rear shocks

[oska]

as per title i think my rear shocks are squeaky unless it's something else

i remember reading something about a certain brand but i can't find it, anyone know anything about it ?

suspension works great it's just i get squeaks when driving over undulating roads

it's driving nuts in an otherwise very quite vx

if it's any help the car was originally fitted with air shockers the nipple is inside the petrol cap must of been some sort of towing package/upgrade

the rear shockers were changed at some point as the nipple is no longer connected

the car was only serviced at holden dealers (have log book) at the time i bought it
