Mein Auto: 2014 535d x drive
Front End Crunching Sound/ drive train rumble

I am sorry if this is redundant but I did a search and came up empty, although I remember a similar thread.

My 2011 535i x-drive has two problems which are somewhat chronic and one is getting worse.

First, there is a crunching noise in the front end, particularly noticeable on turns out of my driveway, but occasionally constant, especially driving over expansion joints on the highway. I thought someone said there was a control arm issue but I could be mistaken.

Second, I have a constant "hum" or low frequency vibration in the drivetrain above about 65-70 mph. It creates a resonance in the cabin. I had the car back at 2000 miles for this, they told me they drove another car which did the same thing, but now at 36K it's getting annoying. I am waiting for an appointment but trying to do my due diligence in advance so the session with service goes easier.

Any guidance would be greatly appreciated.

If it happens more during turns and the sound changes with speed then I would suspect CV joints. Take it in.
