It's good to know that there is some one else experiencing this very frustrating and annoying issue as well. On an irregular road the van sounds like a 'beater' with it's clunking sounds. Sad to say I've pretty much given up and thrown in the towel. I've had the left front strut replaced twice to no avail. The lower control arm has been replaced. The rack and pinion replaced, and most recently the left half shaft replaced. The servicing tech has been very understanding of my frustration, and he too seems genuinely frustrated. He's stumped and honestly doesn't know what to do next. My vehicle is a lease with another 13 months to go and I'm doing my best to try and ignore it. I really like the Pacifica (my second one, plus 4 Town & Country ) and was hoping for a third, but that may not happen since this has definitely soured me.
