Очистка крестовины рулевого вала Audi A4 B8 если тяжело крутится или закусывает руль

A temporary solution if there is a problem with the steering wheel jamming. On the Audi A6 C7 I ran into this problem, it felt like the steering wheel was spinning hard at speed, as if it was resting on something, and then everything was fine again. But before changing the steering shaft crosspiece, I decided to clean and lubricate, as a result, 6 months have passed and the steering wheel turns easily. For cleaning, I used: engine cleaner, brake cleaner, liquid wrench grease and copper grease. My blog on DRIVE2 https://www.drive2.com/users/mark47/
