I have a 2008 120 diesel GX manual. Under hard acceleration the steering wheel starts to buzz, i.e. it has a high frequency vibration coming up the steering column.
I have rebalanced the wheels, the wheel bearings are good as are all the bearings on the diff etc etc.
I have had a look at the "backlash" on the front diff. The bolts on the input flange rotate approx 11mm, the rear diff rotates approx. 4mm. I have asked Toyota if the backlash on the front diff is a) normal and b) if not, would cause the vibration. No answer so far! Any thoughts?
I have checked all the undertrays and they are secure.
I have recently changed the front diff oil.
I would appreciate any thoughts / similar experiences.
