I can hear my rear just a little. I have 4:30's with a Spool. A little bit is expected on mine now because the shocks are tied to the cage and the ladder bars are solid mounted to the chassis with SOLID Bushings. It is very minimal at best. I can also hear the chassis more. It makes noises through the cage and I can hear the shocks clicking etc. All is expected though because the cage runs throughout the car from front to back. Sounds travel through the tubes.
