Solid cast steel front lower control arms were phased into production
during the 1985 model year for 2wd Vanagons and during the 1989 model
year for
Syncros. The earlier stamped arms used a removable solid steel end piece
for mounting the lower ball joint to the hollow arm. The earlier 2 piece
design allows for replacement of the lower ball joint without as much
disassembly of the front suspension. This was perhaps a greater
advantage on Syncros. My guess is that the solid design was intended to
be more resistant to corrosion over time. AFAIK, the steering geometry
remained the same.
