I had this when I bought an old XX4 and ran it before converting to the X5. I bodged it by super gluing a peice of card onto the top deck(?) bearing face to remove some of the play. It really was a pain and I wasn't happy with the bodge but it was either the chassis or top deck, or both which is big £££. It did work though I only ever ran it for 3 meetings before converting so not sure how long it would last.
