Original KICKR squeaking / removing arms

Hi

I have an original KICKR that has been flawless for the 4+ years ive had it.

Last week it started making a terrible 'squeal' noise only when the watts were up and I am standing up. Sitting down is fine.

I have checked everything on the bike, lubricated the chain, dropouts, quick release and anything else that moves and also tried on a different floor surfce. But the noise is still there.

I believe that the noise is coming from the main legs (supports) as I can replicate the noise if I move the bike side to side.

Has anyone had this issue?

Does anyone know if these can be removed for me to try and lubriacte them?

Thanks
