2013 Western star 4900 FA really rough ride. Went to the shop and checked the springs airbags shocks and u bolts. They said all look good. Loaded bobtail or empty trailer whenever I'm going over rough patches in the road truck feels like it doesn't even have air ride. Very stiff. It is a car carrier unit I checked the frame also and the headrack where they connect with eachother. Cab bags and bushings also checked.
Very noticeable on small bumps of any kind and pot holes. Feels like its coming from the drives and cab is bouncing alot as well
Had a trans job and motor mounts done recently rode fine for about 2 weeks until I noticed. Any ideas? Thank you
