2004 Ford Expedition 4.6L 2wd Eddie Bauer 165k miles
This is a stumper.
Ever since the car was new practically, there is a low roar in the drivers side wheel. It is super annoying over time.
I remember my Father talking about how he asked the dealership if it was a lemon and they looked it over and said it is exactly like all other Expeditions that year.
Over the years, I occasionally try to solve it and nothing works. It is not tire noise, it is not wheel hub assembly /wheel bearing (that has been changed twice), it is not Ford leaving out the wheel well insulation (according to the dealership).
It doesn’t happen on the passenger side.
It doesn’t get worse, it just roars.
It appears most loudly around 40 to 50 mph.
Help – my mechanic is stumped and the dealership just want to replace everything but has no clear plan.
