Well, after flushing the system this weekend I also installed a set of 'Sulastic Rubber Springs'  https://www.sulastic.com
on My '05 3500, and I replaced the coupler on my GN trailer Cushioned Gooseneck Coupler 
I have to say, the combination of creamy steering and a feathered cushion ride has my dually riding and driving like an Escalade!
