Hi guys

For a while iv'e been having problems with gearbox
its making a weird sound and heavy vibration round 120kmphand higher.
When i engage the clutch the vibration and weird sound is gone disengage clutch vibration and weird sound comes back.
Now i know it could be the release bearing but iv'e change the clutch,flywheel and release bearing all brand new problem seems to be inside gearbox differential bearing etc
what you guys think
