Upper and lower balljoints are a requirement for any of these cars, if they haven't been done.
The way to tell is to look at the rubber boots; if the boots are bad, the joint either is or soon will be.
All these cars are at a minimum 13 years old; the rubber is disintegrating, so the joints will wear quickly after that.
Vacuum lines, bushings, pretty much everything rubber will need to be replaced if it's stock in the next five years at the longest. Do ALL the vacuum lines and evaporation tubing now, and save yourself some diagnosis time...
I have 2 96 Cougars, and both have had to have this stuff replaced; it's more due to age than wear at this point... One has 240k, one has 140k, but both have had the same issues.
Check the toe compensators on the rear suspension arms; their bushings seem to be my latest issue, lol.
Glad no one was hurt!
