Because I ride a lot gravel roads and offroad, I was tired to change bearings for rear suspension
I decided for small modification.
Original there is one 20x26x20 needle bearing and 4,5mm sealings, but there is enough space left. So my solution: 2x 14x26x20 bearings and 4mm sealings. I don't know if it works and helps, will they hold longer... But after first ride on gravel, annoying noise is gone and feels more stable.
It will be interesting for me had someone the same experience
