We report the detection of outflowing molecular gas at center nearby radio galaxy NGC6328 (z=0.014), which has a gigahertz-peaked spectrum core and compact (2 pc) young double lobe tracing jet. Utilizing Atacama Large Millimeter/submillimeter Array (ALMA) CO(2-1) CO(3-2) observations, as well novel code developed to fit 3D distribution kinematics, study we find that bulk is situated within highly warped disk structure, most likely result past merger event. Our analysis further uncovers, inner regions (R<300 position angle aligning with jet (150 degrees), existence two anti-diametric structures kinematically detached from main disk. These trace jet-induced cold outflow total lower limit mass $2\times 10^6\,\mathrm{M_\odot}$ mass, corresponding an rate $2\,\mathrm{M_\odot\,yr^{-1}}$ kinetic power $2.7\times 10^{40}\,\mathrm{erg\,s^{-1}}$. The energy required maintain such aligned mechanical
