I’ve had a vibration towards the front of the car developing over the past 3 or 4 thousand miles.
Firstly it manifested itself only when braking from around 50 - 70 mph.
My very good local garage correctly diagnosed a front disc issue, found corrosion on the rear face, between it and the hub, cleaned both surfaces and that issue became a lot better, proven with a before and after check on the mot brake machine.
At the weekend I had new tyres fitted and balanced by the same garage, Michelin Latitude Sports. I then towed a heavy trailer on a 400 mile round trip with no issues on Sunday, this would have tested the brakes.
Monday I took the car on the dual carriageway and all was well at 70.
Last night I towed our heavy horse box complete with horse, again with no issues (although we didn’t go faster than 40).
This morning on the dual carriageway a severe and continual vibration, seemingly from the front, started at 55mph and was there until 70 when I slowed right down to stop it. It’s so bad you can’t travel over 55 at the moment.
It’s booked in for the same garage to have a look later, but before that is there any pointers anyone can give?
I was wondering about the prop donut in addition to a buckled wheel, tyre weight coming off etc. I have always wondered if there was a slight low frequency rumble before at around 60, not sure, but I could have been convinced there was something there.
Any help greatly received as the garage is an excellent local outfit but not a specialist in Mercedes.
