Explorer XLT 4 WD SOHC 126M miles.
Experiencing and getting worse, a vibration, whirring, cyclical, almost ticking noise and feel thru the floorboard and steering wheel. Seems to be coming from left front wheel area. But I know that noise/vibration can be telegraphed from another area.
Noise increase and decreases with speed and doesn't change when coasting in natural. Moving to 4WD has no impact on noise. Nor does turning left to right. The noise/vibration Stays the same.
It is more pronounced on different road surfaces and driving on snow covered road has no effect on the "noise." Tire rotation seemed to reduce the intensity of the abnormality, but still exists. Tires checked out OK. Although I'm not certain the shop manager who rode with me and heard the noise was very interested in helping to properly diagnose the condition.
So, I'm on a quest to get an idea of what the possibilities may be. Brakes were changed less than two years ago and noise was evident prior although not as "loud" as it is now.
If you are close with shop manager safley lift vehicle on hoist spin all tires and listen to backingplates with stethescope if unable to find safley in air put in drive lift foot off brake do not accelerate let vehicle accelerate and see if noise is present does the noise frequency increase with speed?
