Dearborn (see city website, no point in linking as these links change so much over the years): decline in straight-ticket voting for both the two major parties. Decline in votes for both major-party nominees. Increase in third-party vote. Results similar to 2012, though Dems fell more than GOP.

Detroit: this is the one that gave Michigan to Trump. Votes for the GOP nominee were up from 6016 in 2012 to 7662 in 2016. Votes for the Democratic nominee, crucially, were down from 281,382 in 2012 to a mere 234,328 this year.
