Our 2015 with 55k miles is really unpleasant to drive on washboard dirt or gravel roads. I’m well aware of the LCA bushing issue and the fact that we are well past the 40k where it begins to show. It bothers me that I cannot pry the LCA back and forth enough to see much wear or use the full-lock steering wheel wiggle technique to reproduce the knocking sound. Any suggestions how to confirm this wear? Is there anything in the engine compartment that could be loose and knocking heavily?
