When I do a sharp left turn (like in runabouts or hairpin turns) I hear a rumbling noise (a grumbling sound, often also like rubber rubbing against metal) from the front of my car, also I can feel a shaking.

  • This only happens when doing a sharp left turn. When driving straight, long stretched left turns or right sharp turns there are no unusual sounds.
  • I need to have a certain minimum velocity for the noise to happen, I think (unsure) that I need to have torque on the wheels.
  • There are no suspicious noises when steering at the extreme left on a stationary vehicle.
  • The sound/shaking happens during the entire left turn (provided I keep steering sharply and maintain speed), not only on the beginning/end.
  • I tried to check the suspension. A first rough check did not reveal something unusual. There is no feel-able play on the joints.
  • On the CV Joints there is also no feel-able play and the rubber boots are intact.

I made a video, the rumbling happens at 00:05. Since the roundabout is a bit larger I could not perform a very sharp turn. The noise happens only once when I was oversteering to reproduce the noise.

Some informations about the car

It is a 2009 Opel Astra H Caravan with about 150 KKm. It is a FWD, manual transmission. I also have a illustration of the suspension.

I am inclined to suspect the CV Joint of the left side, perhaps somebody could point out other candidates or checks?

  • Have you checked the wheel bearings?

  • @SolarMike I tried to rock the wheels while the car was jacked up. I could not feel any play

  • Ok , then , as you pointed out, you need to check the cv jounts inner and outer

    You have to check them for play at all the possible angles that they can move through.

    With wheel bearings, you really need to hear what they are doing. There may not be any lateral movement of the bearing at all, but you'll most likely feel/hear it if it's bad. You may want to use a automotive stethoscope to actually hear it better. Aug 7, 2017 at 16:07

Turns out the stabilizer bar shifted and scratched against the body behind the wheel well.
