Lots of noise in front end--bumps etc.
Need to know if bushing only can be replaced and not complete control arm w bushings. Where is best place to purchase bushings if so.

obviously at high mileages, however the rear bushing of the front control arm were worn out at probably 130k or so, and the front bushing of the front control arm just gave out at 172k. replacement is about $300 per side that is affected for just the bushings. My mechanic got the part from volvo. The control arm itself is solid.
