Mrhawx Posted November 10, 2017 Share Posted November 10, 2017 Bought a B7 3.0tdi Quattro few months ago, in 4-5-6 gear under heavy acceleration before 3000rpm i get a huge vibration thudering coming from under the car. I thought it was my propshaft bushing, replaced it but no diffrence. If i go over 60mph the car starts shuddering slightly. Any Ideas?

Steve Q Posted November 11, 2017 Share Posted November 11, 2017 Welcome to the forum Calum :) You'll find the members on here are a friendly and helpful bunch :) I'm assuming when you've had the prop bush replaced , do you mean the propshaft bearing? If so and you've changed this then I'm wondering if it's the prop itself or your rear diff? Sorry I can't help more. Cheers Steve :) Quote Link to comment Share on other sites More sharing options...
Mrhawx Posted November 13, 2017 Author Share Posted November 13, 2017 Hi Steve, It was the carrier bearing and bushing i replaced on the Propshaft but didnt make any differance. I checked the drive shafts today but no play in them either. Do you think it could be a diff going bad or a bushing somewhere?
