I opened up the water pump on my 99 WR to change a leaky seal and found the impeller had sheared from it's nut to leave it free behind the nut ! :)
It's obviously still been turning as I haven't overheated and also by the marks......
Has anyone else had this prob, if so did you use Yam parts again of is there an aftermarket alternative ???
