Did you try rotating the tires maybe front to back to see if noise disappears or moves with the tire? Otherwise maybe a wheel bearing.

Front wheel s making humming noise


sounds like a wheel bearing assembly to me. i would have the clearance checked at a jeep dealer. if you can rock the wheel gently while moving forward and the sound fades and comes back, definitely a wheel bearing assembly.

1996 ford contour loud humming noise and vibration from front wheels


You have a defective wheel bearing most likely, the noise sounds correct for that problem. have a shop drive it before you replace anything to confirm my guess.

humming could be wheel bearings - jack car up and spin wheels - they should feel and sound smooth. Grab top and bottom of tyre and try and move backwards and forwards, if it does - whell bearing shot or needs tightening.

Transmission noise could be a driveshaft or gearbox mount being worn / broken. Jack up and move all these bits about and llok / hear for movement and you'll find the mount.

They now have a bearing assembly, you replace the unit as one. The humming sounds like a Blazer I did last week. Same noise/humming over 25MPH..? Sounds just like road/tire noise. Hope this helps.

If the noise changes when you turn side to side while driving you have bad wheel bearing. (Hub Assy)

Steering creeks when turning left or right. front wheel noise.


My advise is when u get a humming noise when banking left or right. Its beter to change both left and right wheel bearing and ball joints. Cause if u think about it those parts are put on at the same time . So if u think about it they have the same where in Terre . left or right hope this helps you.

2004 GMC Yukon Denali Awd humming sound in front of truck


The Denali's are really susceptible to front dif. wear and failure. Because it is AWD, the front dif is always working unlike a 4WD. GM, in order to lighten up the front end built the front dif in aluminum. If it was the same as the rear, it would be bullet proof, but much heavier. After about 80,000 miles it is common to have bearings failing. Remove the drain plug which happens to be magnetic. You may see more than just the normal fine filings. You will likely see larger chunks of metal some of which is not even magnetic but will drain out with the oil. You are likely looking at a $1500 rebuild. It will get much louder and run for a long time before it really goes south.
