Posts in Sound dampening

I have been aware that the U-bolts that hold the springs to the axle are about an inch too long. I got the grinder out last night and lopped them off. I also installed a new stainless steel split pin on the damper. I have also purchased some sound proofing/dampening stuff. I am going to put it on the large flat surfaces in the cab, i hope it reduces the noise a bit.
