I have a growing issue with my 21 3500 Laramie.

When I hit bumps/go over railroad crossings, my brake pedal rattles.

It's not affecting use, thankfully; just more of an annoyance.

I took it to one dealer, and they said it was "fine" and blamed my lift on making the rattle more amplified.

I remember hearing that there might have been a recall or TSB on this, but I can't find any documentation to back this up.

Anyone else experience this?
