Folks, Another newbie thread, pardon my intrusion... I need work on my Xterra. It's been making a grinding sound when I am driving. It gets worse when I steer to the right. In the old days, it was a CV joint on my Sentra or Stanza. But this is a truck, so I don't know. It's been bad for about two weeks now. Last night it started getting much louder. Along with the grinding sound, it also started "clacking". It was particularly noticeable last night when I was parking in a parking garage (low speed) Any suggestions?
