I don't know about Chrysler, but I know GM issued a tech service bulletin a couple of years ago strongly advising dealers to not do any Bilstein or similar type flushes, since the chemicals used for the flush may be incompatible with bearings and seals. Of course most of their dealers have these in place for reasons listed in the above article. If you change the oil every 3-5k miles like you do I can't imagine there would be any sludge buildup to worry about. Also, one of the first things I was taught in auto mechanics class is that if there is sludge in an engine, do not disturb it, unless you are doing a complete top to bottom engine overhaul. The reason for this is you may not get all of it out and then some residual sludge ends up finding its way into the bearings and wipes out the engine.
