got a pair of inner gaiters today as the leak is getting worse! Thing is, when I last got some they came with a nylon bush inside them, these havent. Dealer has checked numbers and says that is how they come now so if I fit them as they are it will still leak right? He then said there is a bearing listed and so I said Ill have them, however he said its only shown on one side but lists two... as eper is down I cant check it, any ideas please?
