Mike what do you mean by prepping the hubs ? i did clean them when i fitted the discs just to make sure there was no crap in under the disc.The first hundred miles or so there was no wobble and i was told to do 200miles bedding them in which i did.The problem occurred at about 140miles.What problems can the pipes or flexi hoses cause ? or what symptoms ?.I have got to go out in about half hour so i will see at what speed is more noticeable.
