Steering wheel shake at idle

Friends I have 307 2002 xs. I put the car in periodic maintenance today. I did not go myself, my father took me. The cartel casing was broken, they boiled it, and the axle heads were extra. The car came from a maintenance point, I run it at the wheel while idling, and there is a humming in the style of snoring snoring. In the exhaust, it makes pööölü sound in the same sync. The possibilities that come to my mind
1) can engine chocks cause steering vibration
2) The engine of the car takes air from the binder, while the exhaust makes the paste.

I would be glad if he knows or has an idea. By the way, the car does not have gasoline cylinders.
Thanks for your valuable ideas in advance ..

If the cartel housing is in contact with the engine, idling may also cause vibration. Other possibility, if the ears of the engine have changed, the direction of the lower axle ear may be different, some masters may also be the problem.

I just took it. The sound of working like diesel comes entirely from the exhaust.

If there is no abnormality in misfire vs gas in engine operation, catalyst or muffler is dispersed.
