Hello All,
First time here,
I have a 118k Mile 2009 E350 recently I’ve had a noise coming from the rear of the car, this started off very quietly but progressed to a decent volume, I’ve replaced the rear bearings on both sides, this made the noise ALMOST go away … for about 2 days then it returned.
Any other ideas of things that I should check?
Details about the noise :
Changes volume and pitch only based on the speed of the car, putting it into neutral whilst at speed makes no difference to noise at all, there’s no change as it shifts through the gears. Purely related to speed.
For the level of noise reference, at 70 mph it sounds like you’re holding 3500 Rpm or so.
As mentioned I put new wheel bearings on the rear and it came back after only 2 days.
I appreciate any input or suggestions.
Thanks
