Just started noticing it occasionally maybe a few months ago. Starting to become more pronounced. Happens when going from say drive to reverse and it will click (can feel it in the steering wheel) when I first start to backup after having gone forward. Also happens if I inch really slowly over a speed bump but it doesn't happen if I drive faster over the speed bump. I noticed that the new service check and inspect items have some items related to torquing steering components. Wonder if this is related?
