front suspention on 1998 Volvo C70

I changed the whole front strut assembly including the mounts and spring seats ..the ride was somewhat better but started acting up again..any suggestions on solving the problem

When you say acting up, do you mean the car is "bouncy" like the shock/spring doesn't dampen correctly or do you mean you hear a creaking or other such noise?
Change ur control arm they wear out fast I changed the struts too was better an got new tires was better but change the control arm drove like a new car :)
