Hello, I’m supposed to repair the Omega for a well-known…. The track rod heads are completely in the egg (while driving the tires from right to left nd steering wheel has 5cm game) a new endpot should be under, and above all what’s wrong with the diff and or the drive shafts…. at the beginning I noticed that the car in very narrow curves that you drive slowly strongly vibrates and a rear tire is significantly more worn out than the other… Now when driving is permanently such a beating noise to hear.. If you drive quickly, then something cracks really loud… now I wanted to ask how long it takes diff and drive shafts to repair… and what do the parts need to cost the grotti? mfg
