2019 Toyota Prius AWD-e Liftgate Support Strut Replacement Cost

Since the liftgate support strut is attached to the liftgate and the chassis of the vehicle, the support struts must be able to extend and retract without bending or breaking away from the mounts. Also, due to the weight of the liftgate, they must be able to hold weight, yet be balanced enough to allow the average person to pull the liftgate down. For these purposes. the part was designed as a very small shock absorber. Filled with inert gas or hydraulic fluid, this strut (or shock) is always attempting to extend itself. Internal pressures push two rods against each other, and one is mounted inside the other one. This causes the liftgate to be very easy to lift, as the support struts are doing most of the work. however, the liftgate struts cannot be too strong. They must only have enough force to push the liftgate open, with the addition of a few additional pounds amount of pushing force. This prevents the liftgate from falling when the wind blows, or if someone bumps it while it is open. When the liftgate is closed, one half of the strut will slide back into the other half, being forced by the user placing constant pressure on the liftgate until it is closed.
