Thanks, Dennis. I suspect the front, and am prepared to deal with it today, but just wanted to check. The rears are mainly suspect because of the high mileage on them (as much as 355,000 if they are original).

I was going to amend my opinion on the rears anyway. I went back out and checked; they have no play in the horizontal axis but a little in the vertical axis, if I grab the top and bottom, that is.
