I have a 1997 Jimmy and when it is in 2wd and I get up to about 80 km there is a loud buzzing coming from what seems like the front passenger side( general tire area, and will continue to buzz until I slow down to abbot 15km. Then I hear a *click* and it will go away until the Next time I drive faster. Also, this noise will go away if I put it into 4wd... Does anyone have any ideas what this could be? Wheel bearing maybe? Thanks
