Hello, I have recently changed all of the bushes on the front of my Mk2 Fiesta XR2 as i was having trouble with the front tie bar knocking against the chassis every time i changed gear. I also had a loud rubbery squeeking and squarking from the front end as i turned the steering. I thought that changing all the bushes would cure this. The squeeking only seems to occur when the car has warmed up. After changing the bushes the knocking has stopped and the front end feels nice and tight as it should but as before the squeeking and squarking from the front still occurs after i have drove 10 - 15 miles can anyone tell me exactly what this could be?
