Known issues on the 2003 Astro. Three recalls are on the record for this year, and the front suspension carries the most consequential one: the lower ball joint boot can be cut where it interferes with the steering knuckle, and a ball joint that loses its seal can eventually let the knuckle separate from the lower control arm and drop that corner of the van. A replacement fuel filter that leaks at its connection and replacement lamps without amber reflectors are the other two. Suspension shows in nine of the 89 complaints, behind 21 on brakes and 14 on electrical.
