Midea washing Machine, loosing its mind when on spin

We have a Midea washing machine, just under 4 years old, it's an 8kg top loader. And when on spin cycle is just banging against the side, makes a massive racket and then just starts to wobble and cuts out, returning to the start of the spin cycle again. Would it be a bearing? No idea but need it looked at as at the moment I am putting my back out as the only way I can get it to complete a cycle is to brace it so it doesn't wobble.
