Replaced the UCAs on the Mark (again) - last time was 2018 and ~90,000 ago. One side was rattling and the other was OK but I figured "replace them both."
Should have only taken 20 minutes or so a side, but the darned air solenoid boss was in the way of the bolt so I had to remove the shocks from their upper mounts to get them out.
But hey, now that the entire front end has been refreshed I better be good past 300,000 miles!
