Squeaky rear suspension GP2?

[tomaskriv]

Hello all,

I have some issues withbrear suspension on our C4GP 2014... Sound like squeaky metal parts rubbing, noise is high pitched. The rear shocks were replaced. But I cant tell if the noise started after this repair.
Found information online about noisy rear axle. There is some PU foam fix available.
Maybe someone had this issue?

Thank you all for any information.
