Indesit WIL163 drum removal

Hi

My Indesit WIL163 washing machine started making a lot of noise on the spin cycle. I found some movement between the inner and outer drums and suspected the bearings needed replacing. I removed the spider at the rear of the machine and found that the bearings did have signs of corrosion, so I replaced them and reassembled everything. However, the machine still made a lot of noise on the spin cycle and there is still movement between the inner and outer drums. I’m now wondering if the shaft attached to the inner drum has come loose as if I wobble the inner drum, the shaft seems tight in the bearings and does not move (it turns ok).

Does anyone know how the shaft is attached to the inner drum and if it can come loose? If it can, how easy it is to remove the inner drum and fix it? I assume the outer drum opens at the front, but can’t figure out how.

Any advice on whether this can be fixed gratefully received.

Thanks
Adam
