Did a search and not too sure if my question has been answered yet.
I have a 2001 jimmy 4wd, 115kms.
Above 40km I can hear a high frequency humming noise comming from the front. The noise is dependant on vehicle speed not engine. It gets louder the faster I go. The noise is progressively getting worse. I can feel the high freq vibration in the stearing wheel.
I have jacked the front and the wheels/hubs feel secure. (no wobble ) Tire pressures are ok as well.
I don't think my 4wd is engaged, - back end slides around when I gun it on gravel.
Is this a bearing?
Thanks for the help.
