Get a second diagnosis and estimate. Fix safety & drivability issues. Does your wife like the van enough to put up with a squeak? I'm from Long Island originally...... Jersey roads weren't much different ... only so much you'll get out of any suspension before it starts to complain. Anyone remember the Belt Parkway--mid eighties?
