I changed the front factory sway bar links at 40,000 . It happens to all focus. Its a 95.00 fix at The dealer and they will install the same crappy factory parts.
For about the same price you can buy superior parts online and install them yourself. The Moog parts feature grease fittings, which should result in them lasting the life of the car
All you need is a torque wrench and a good jack. Good luck http://www.autopartswarehouse.com/de...QMOK80066.html
