Can someone help me understand what the purpose of the springs at the rear of the cab are? As much as I seem to jiggle around (trying to talk on the phone is almost impossible on a less than perfect road due to my voice quivering) I'm thinking of going to a solid mount but would like to know what their purpose is before I just throw them out.
