Hello,
the problem concerns the Opel Astra, but it may also apply to many other cars with this type of suspension.
At a speed of 25 km / h you can hear quiet vibrations 2x / s (probably near the left side, near the wheel), at this time no vibrations on the steering wheel. These vibrations resemble the runout of an unbalanced wheel.
At speeds above 100 km / h, strong vibrations are transferred to the steering wheel, with increasing speed they are slightly larger, but generally at a similar level. Of course, then the vibrations can no longer be heard, but they can simply be drowned out.
With quick and short movements of the left-right steering wheel, you can hear a slight knock on the turned off and on the engine. (However, this knocking was also before the appearance of the above mentioned vibrations and vibrations)
Discs + pads new. Suspension checked in two stations, rods, connectors, pins, etc., no defects found. The steering gear has no oil leaks, no visible defects cover. Wheels balanced 3 times, perfect condition. Also transferred from another car, the problem does not occur. When starting on twisted wheels, I did not notice a symptom of worn joints, although I always have a habit to move gently in such a wheel position.
When shifted into idle gear, the vibrations do not subside. Do not feel any bastards or knocks when moving off. When braking heavy vibrations, the car brakes smoothly.
My initial diagnosis is the driveshaft, more precisely the inner joint.
Please help what you think, maybe someone had a similar problem.
The mechanic is any other version, and after the last three repairs and money thrown down the drain for replacing the working parts, I find that it is better to discuss on the forum than ask "experts".
I am asking for answers related only to the topic and not to deviate from it, because surely many other people who have such a problem will use your help.
Let us not end the discussion that begins with the topic of transmission of vibrations to the steering wheel in a polemic about fuel quality at various stations.
