One problem related to ball joint has been reported for the 1999 Ford Windstar. The most recently reported issues are listed below.
The engine carriage is rusted out, and the rear axle is cracked due to rust. The main arm of the ball joint is completely pulled away from the frame because of the rust. I contacted baab Ford in reed city michigan, because I was told by the mechanic I took it to originally that this was a recalled product. Baab Ford told me yes it is a recall issue, but no they wont fix my vehicle because the VIN doesn't come up as one of the vehicles effected by the recall. I contacted Ford motor company as they had advised me, Ford motor company told me, my vehicle isnt on the recall list, regardless of the fact that it has both of the problems that 1998 - 2003 Ford Windstar was recalled for. The vehicle speeds up whenever it hits a bump and also pulls towards the center line especially on slippery roads or where loss of traction occurs. It also wears out tires every 2 weeks.
