i recently replaced both sway bar links on my sons forester he drove about 100 miles no problems then developed an intermittent clunking that i could feel through the floor, steering wheel, etc. no worse when turning. i removed the links and drove it on my road same as had yesterday when i got lots of the noise. no noises at all with links removed. bushings seem good but dry, i did hose them down with wd40 last night but there is no play in them. any help would be greatly appreciated.
