Hi Mark,

There will always be fluid in the rack boots so it is necessary that the convolute covers or boots be free of puncures or tears and the large and small bands on each end be tight.

If you have lost a lot of fluid then you will have to refill the rack. It holds 1/2 pint. According to the manual, the rack must be removed from the car to fill it. I have been able to fill it through the damper pad cover. You can add oil but you will not know how much oil is in the unit.
