I purchased a 2109 Silverado about a month ago with 60,000 miles. I noticed the outside edges of the tires were worn so I took it for an alignment and it was toed in quite a bit, after the alignment the results show it was back to normal. After driving for a few weeks I’ve been keeping an eye on the tires and I really think they are still wearing. Every now and again when backing up and turning to the right I notice a slight pop that sounds like it’s coming from the front drivers side. All of the bushings and everything look normal, what else could be causing this?
