theres no noises at higher speeds, as I stated I just drove to Ocean City MD and back, over 650 miles. The car rides smooth, that's why I dont think its the axle. still steers fine and handles good. Possible Sway bar or strut mounts

 

I've got some front end clunking on my X too lol. I think my SPC ball joints have already gone bad even though they are only like 7 months old.
