^ Welcome to [FJ].
If your
SVT Focus's suspension is all original with 6 years of use, you may want to think about replacing the dampers (struts and shocks) with a fresh set if the car has 85,000 miles...
You can buy factory-fresh
SVT dampers in a damper kit (no springs) that includes everything one needs to freshen up the suspension except bushings (which you prolly don't quite need).
You get new strut top mounts, new strut bearings (that support the weight of the front of the car while allowing the front MacPherson struts to turn with the steering), new strut top clinchnuts, new urethane foam jounce bumpers (bumpstops mounted coaxially on each damper shaft), etc...
All for prolly less than $195... Here's the
SVT Focus Damper Kit which one can purchase through either
LCRacing or
Tousley Ford (Steve at Tousley sells all OEM Ford parts at 10% over cost).
