bloody hell - clutch shudder

[Maj]

Those 6 studs should be locktighted in , common prob for them to come loose , no need to remove the centre nut unless you want to get to the gps , few tricks to know if going in deeper , a service manual would help from there

Check the inner hub , will be loose if the back torque limiter is std ,and solid if its been welded , given your shudder it can't be welded, as that fixes the shudder but looses the extra tensioning on the clutch pack the btl gives
