Hello All. Just had my F type out for a little exercise as we are finally slipping out of winter's icy grip. I've only put about 200 miles on it since purchase purchasing in December (best time to buy convertibles, but, horrible time to do test drives). This car has just over 12,000 miles on it, so, pretty new mileage - wise. It is a 2014 convertible. Is CPO covered for two more years, fwiw. Anyway, I notice quite a lot of noise coming from the rear wheel (driver side only) suspension area. At low speeds, it is sort of a knocking noise, or thumping. It does smooth out at highway speeds. When I did a hard acceleration I really heard a loud knocking that then went away. Dropped by the dealer, said, not too surprisingly, has no knowledge of issues. I had a '16 F Type coupe that would occasionally thump when coming out of slow turns on steep inclines, but, this car sounds like something is broken or worn, way worse. Any thoughts before I schedule a dealer visit? My dealer said to drive it harder to hide the noise! Thanks for any ideas.

 

There was a service campaign for low-speed rear-end thunks for MY14. Will take some searching, but it's on here. Mine was never bad enough to have it fixed.

 

yes, service bulletin to address this does exists. check the sticky on the main F-type page for known issues, its talked about a few times with in.

 

look for JTB00306 .
Rear springs need some isolator sleeves to be installed .

I thought mine just needed the isolator sleeves too...turned out being the differential

 

I've seen quite a few of the diff lock motors fail, causing noises while turning.
