Wheel Wobble/front vibration Found.............

Hi
all. been having slight consern's as been having slight noise from front of scooter .
But really put it down to scooter normal or loose plastic .
As from previus blogs .and handle bar wobble was normal ??.
having slight noise from front of scooter .
Sounded like plastic mud guard was little loose so check all around mud guard and thought some thing was caught .
nothing seems loose so. after another few months hering this sound on and off
Again. do the same again so thought the front wheel calliper was loose .
no all seems to be ok few months later things are getting worse now getting wheel wobble this morning as i was taking my son on the back to work .
i said to him that this has got to be the wheelbearing and sure enough looking at the front wheel ( the oposite side to the wheel caliper ) the wheelbearing housing
shroud. had come away from inside
wheel and thought that the wheel was burnt black around where the bearing housing is but no its all the black gunk thrown out of the hole grease and was cool to tuch so i have had to limp home help please..............
Has any one had similar problems very / suprised as my vectrix has only done 4750 MILES and
age is aprox 17 months old hope its coverd under warranty..
as i know that the weight of these scooter is alot but suprised the wheel bearing only lasted this long .
kev .
ps i know i was going to loose some weight next year 2010
but didn't expect to down my trainers and walk to work so soon 3 hours each way + 10 hours working days me thinks am gonna be knackerd all time .
or out come the old push bike comments appreciated
thanks kev
