I need to have the suspension on my '95 850 turbo checked out for a peculiar rattling/noise that is present when going over bumps. I'm pretty sure it's coming from outside and underneath the car so I've ruled out interior panels or pieces rattling. Of note, I had my car serviced recently and while I was in, I had them lube the steering stops which seemed to cure the problem....for about a week. The noise is back and just as loud as it was before the lubing. My car is riding on a modified suspension: Bilstein shocks, Eibach lowering springs, IPD sway bars and 17-inch, 40-series tires. Can anyone offer me some info. regarding my problem? What are '95 850s susceptible to in terms of suspension problems in general that I should look out for?

Thanks for any info, it's always appreciated.
