What Ricky Bobby sez. I didn't note your mileage, but shops like this, in my experience, tend to assume replacement of shocks/struts [which on bmws, generally, are a very long life item] when the issue is more often ball joints and control arm bushings. Can't speak to availability of reputable indy bimmer shops in scenic Minot, but a good suspension shop, with you providing the key parts, might be the most cost-effective step [including lowering] if you [like me ....] aren't equipped and sufficiently skilled to do the work yourself. Good luck!
