He's probably on about the donut bush in the steering column mate.

The column is joined to the rack by a rubber donut bush. They're like rocking horse crap - I found one by chance unused on ebay. When these perish the steering wanders and is affected more by adverse cambers and tramlines. Had this on mine - the guy that did mine for me said it's a half hour job, if that.

The other one - does he mean track rod ends?
