So my 05 Silverado developed a slight rubbing noise from in the front end that gets worse when I turn left and better when I turn right. Also, twice in the last week or two while turning left in 4wd there has been a loud popping noise with a little bit of a buck that I tentatively diagnosed as a binding CV joint. The axles look ok, no torn boots or anything, but they're old and both front hubs are brand new. I ordered a pair of new axles for the front but now I'm questioning things. Another symptom is that sometimes when I'm stopped at a stoplight and I put it in 4wd, as I pull away there will be a metal on metal clicking noise and the truck acts like it's in 2wd until the clicking stops. Once the clicking stops, 4wd works normally.
Two questions:
1) Do you guys agree that it seems like it's the axles or do you have other ideas?
2) Bad 4wd actuator? Could the binding CV have caused that?
