The noise sounds a bit like a moped and starts arround 15 mph and gets louder the faster i drive. Also as you turn it sometimes will make a metal on metal grinding noise. Its hard to repeat this noise it seems to hapen under specific circumstances. Could this be a CV joint? Recently a shop replaced shocks struts sway bar links and one wheel bearing. The car has 70 thousand miles on it. And is nearly all highway miles. I am a little afraid to take it back to the same shop, since they keep replacing parts and not fixing problems. Id appreciate any info anyone can give me.

only one bearing was replaced?take it back and have the other checked.the shop should have told you if it had any c/v issues when they changed out the struts.
