We see hundred's of Mk7 Fiesta through our workshop every year and the majority show signs of deterioration of the rear upper spring isolator bush.
This can lead to squeaks and creaks, as well as a less satisfactory ride-quality due to the deterioration of the OE material.
mountune have address this via a bespoke shore hardness replacement polyurethane bush, that securely locates the rear spring and thanks to the uprated material, reduces unwanted noises at the same time.
Arrived insanely fast. High quality and packaged very nicely. These bushes are super easy to fit yourself. It took me around half an hour. Now I have peace of mind knowing how poor the standard Fiesta rear bushes are. I am very happy with my purchase and overall experience.
