Volvo XC60 2008/2017 steering rack cap replacement This cap is to replace the plastic cap that holds the spring on the steering rack which is a common problem on these cars causing play in the steering Easy to fit. Just unscrew the old one and fit this new one. It has a 12mm hex so that access is slightly easier when refitting into the tight space. Takes the play out of the steering rack rather than refurb or replacing the rack
