I am getting a knocking car from under my car. It seems to be under the clutch and on the left of it(note we use right hand drive).
The knocking sound is noticeable when you drive slowly e.g. moving off and under 30 mph but you can't hear anything when going fast.
Mechanic 1 says anti roll bar or ball joints. Mechanic 2 says nothing wrong with roll bar or ball joints but rather its the driveshaft by exclusion since the sound only comes when driving. A friend of mine said he had exactly the same thing i.e. the sound is only under 30mph but then goes, they diagnosed him as a wheel bearing and fixed it.
What might be potental causes for my issue, since its the same as my friend had, are these the symptoms of a faulty wheel bearing?
