A joint arrangement for a vehicle, the joint arrangement comprising:

• a joint comprising a joint housing having a radial shoulder portion and an axial pin, said radial shoulder portion having a front side surface, said joint comprising a pivot pin mounted in said housing for pivotal movement, said axial pin having a surface defining an axially extending groove;
• a rod having a cavity and an annular exterior surface, said rod being connected to said joint, said front side surface extending in a radial direction with respect to a longitudinal axis of said rod;
• a sealing bellows defining an interior space, said joint being arranged at least partially in said interior space;
• and
• a gas flow connection connecting said cavity of said rod to an interior space of said sealing bellows, said gas flow connection comprising said axially extending groove and at least one groove, an axial front side front side surface defining said at least one groove on said front side of said joint housing, said front side surface facing said rod, and said at least one groove opening in said axial front side of said joint housing into said interior space and said at least one groove ending with a radially outer end at a spaced location from an outer circumferential contour of said front side of said joint housing, said at least one groove extending in said radial direction, said at least one groove having an outer end, said outer end being located at a radial position outside of said annular exterior surface, said axially extending groove being in communication with said at least one groove, said cavity and said interior space to define a fluid flow path.
