**Help Needed – Mysterious Vibration After Repairs**

Hey everyone,

I’d really appreciate any advice or suggestions on an issue I’ve been dealing with.

About two months ago, I was driving on a country road in Oxfordshire late at night when I hit two dislodged curb stones in the middle of the road. The impact caused significant damage—snapped my front left wishbone, broke the spring and damper, cracked a couple of wheels, and damaged several tyres.

After spending £2,000 on repairs at my trusted local garage (who I’ve used for 15 years), there’s one lingering problem:

On the motorway, I’m experiencing a rhythmic vibration that’s very noticeable at **60 mph**. It gets worse when I turn right but **completely disappears when I turn left**.

We’ve checked and rechecked:
✅ Wheel balancing
✅ Brand new tyres
✅ No obvious damage to other components

My mechanic is stumped, and so am I. Has anyone experienced something similar? Could it be a driveshaft, a hub issue, or something else entirely?

Any input would be hugely appreciated—this is driving me mad!

Thanks in advance.

RPM based
Disappears on turning left
Rythmic

Front wheel bearing, probably left going by damage?

Take a good look at the engine mounts. On the E9X M3, bad or broken engine mounts cause the engine to sit up to one inch lower in the engine bay. Consequently, the oil pan (sump) can touch the sump guard, steering rack and anti roll bar (if I recall correctly). It's possible the same thing could be happening on your 2013 F body 4 series. There are other threads out there on the E9X m3 forum about the issue. Vibration (and or noise) when turning in one direction is typically thought to be a wheel bearing BUT you are also mentioning a rhythmical resonance type vibration which suggests engine mounts to me. When were they last replaced? They have a service life or about 65K miles on an E9X M3 - or less with use of launch control.
