probably correct about bearings.Whole tub has to be removed from cabinet and split.bearings have to be removed from carbon tub and possibly a new spider/shaft will be required.2 bearings and one seal plus possible shaft.Half cost of new one.if you get away with bearings only then under £30 but a big diy job.The choice is yours!!
