I honestly don’t know - auto engineering isn’t my field and I’d be BS’ing to pretend it is. I know why it’s there and I wish I still had access to the Opel I used to help a friend work on - they’re such interesting cars. What did whoever told you that say was wrong with it, exactly?
The donut gasket and bushings are worn out, so the u joint whachs the bottom of the car when I break inertia or shift hard
