    thump, and vibration from the rear....?

    so ive had a constant thumping noise and vibration in the rear in hard acceleration...it can be felt on the rear passenger side...i just replaced the shock mounts with brand crispy new ones...the thumping is still there..i know the shocks are blown and need new ones asap...and the car is sitting in the springs...could a blown shock, riding on the spring cause that? and the vibration?
    i checked the axles and they look ok theres a new diff mount so it cant be that..i also changed the guibo (flex disc)..

    it only happens when hard acceleration, usually starts at around 4.5k rpm and on on first and second on third i cant feel it anymore...
    ill try to record the sound but id have to somehow mount the camera....

    oh one more thing i can hear the thump when i let go of the clutch...
    im suspecting driveshaft?
    any way to check that?

      well theres a little bit of vibration on the shifter but i think it would be normal its been there since i bought the car...
      but the thumping started like a month ago i always thought it was the shock mounts but its not although my car feels a lot more stable on the ground with the shock mounts...
