PeteB Posted August 20, 2018 Share Posted August 20, 2018 We drove over to the coast from North Nottinghamshire to Mablethorpe yesterday. On a few occasions while rolling along in slow traffic, their was a rythmic clunk! I would liken this to rolling over a joint in a concrete road with one axle only! This clunk disappeared if you eased on the throttle. Yet it didn't feel like a shaft was bad or appeared if you coaster at a higher speed. Should I be worried? My automatic Ranger doesn't do this..... Quote Link to comment Share on other sites More sharing options...

PeteB Posted August 20, 2018 Author Share Posted August 20, 2018 Morning Gareth, it is an auto. I had crawl underneath, albeit briefly, and could see no wrong. Will gave it a better viewing later. Cheers Quote Link to comment Share on other sites More sharing options...
fraser d Posted September 21, 2018 Share Posted September 21, 2018 Hi pete. I had similar clunk on my q7. Clunk when pulling away( left right and straight line). Changed front drive shafts and front lower wishbone bushes and made no difference. Even took it to a guy who used to be an audi technician and he no idea what it might be, but said it could be something to do with the drivetrain. Changed the front and rear diff oil, still no difference. Put my gopro underneath the car in several places and the noise seemed to come from the transfer case. Changed the oil and added a bit of molyslip in and this cured it. Seems that the oil after 150000 miles wasn't lubricating the torson diff inside the transfer case. Hope this helps fraser Quote Link to comment Share on other sites More sharing options...
