Hi there just added to this thread. I have a 2015 Sierra Z71 with the 20 inch rims. It is bone stock. Last month when I changed my shocks and struts I noticed wear on my passenger side on the sway bar and on the passenger side inner fender. Changed the struts rubbing is worse. Changed the tires out a month later with stock size and had an alignment still rubs. Got it up in the air checked the front hubs for play and runout no issues. Rims are not bent and problem stays on the passenger side when I rotate the tires. Has anyone found a remedy?
