Added some sound proofing in step well Chevy 3500

Had to pull the step well cover on the driver side to run some wire, figured I would add some sound proofing since the road noise is an issue. There was nothing there between the metal and the plastic cover. I cut and fitted a thin yoga mat but anything that would absorb noise would work. Had to remove the seat but only 4 bolts.

  • Leaving Friday for a long weekend, If it made a difference I'll let you know.
  • I do think the soundproofing made some difference. Hard to say how much but I noticed more road noise coming from the battery compartment under the entry steps. Going to try and do something with that area next.
  • What year is this truck? I've never seen a step well like that on the driver's side of any Chevy trucks.

    It's a class C 3500 Express van chassis.
  • I have a 2006/2005 chassis Chevy Based Tioga and never had any problem with road noise,in fact it is very quiet inside. I also have a battery compartment under the entry steps,it is made of a heavy plastic or composite type of material and the lid/top step has a rubber seal that seals it when fastened down.

    You might check underneath,my exhaust/muffler runs just behind it and there is a heat shield attached to the frame there, although my RV is on a Chevy Workhorse Chassis, I have found that ones of the same vintage on non Workhorse Chassis don't have a lot of upgrades that mine has.

    I have the Workhorse. I think some of it is wind noise from thr flat set face of the rv box just behind the cab doors. Now that I soundproofed the step wells I hear more coming from the step area. P.O. used to hang a blanket over the door but the door is not where it’s coming from. I worked construction for 45yrs long before anybody suggested ear protection so my ears are shot. I hear a lot of white noise anyway so that’s probably part of it.
