Well I think my CV shafts in my 96 S10 Blazer are going to crap. I back out of my buddys driveway tonight and as i turned my wheels back straight I heard a succession of pops and one more when I started forward. Ive heard a few now and again we i start going forward with the front wheel turned. My blazer hasnt been in 4wd for at least 2 weeks though. Do my CVs free spin when I drive down the road? And does this sound like they are going bad?
