Chevy Malibu humming sound increases with road speed?
Have a 2004 Chevy Malibu. Just got the axle seals and transmission seals replaced
because of significant leaking. After the replacement the transmission issues (sluggish,
slow shifting) disappeared. However, a new symptom has appeared. As road speed
increases, a humming/roaring sound is heard under the car. Any thoughts as to what this
did you have the tires rotated? the shop should swap them back free to find out if thats the problem
I did not have the tires rotated. I have had tire issues on a different car. The noise sounds more centrally located.
Sounds like the cv axles were either damaged or not seated correctly.
wheel bearings could be worn.. bad hub(s)
is it the bearings that go into the trans??
Hub Bearings on the wheels themselves
