About a week ago I pulled the front end apart because I had a poping sound in my front end. Thought it would be my cvs but found out my knuckle bearings were toast. I replaced the seals and bearings and put it back together and for a moment I thought it stoped the poping but its still doing it. I'm about to pull the axels out again and go thrue the cvs. When I'm going on level ground strait or turning right it doesn't pop. But when I turn left it pops like crazy. Does this narrow it down to one of the cvs? The poping sounds like it's coming from the left but I could be wrong. When I get these axels out how can I tell if a cv joint is bad or not? Thanks
