I replaced my lfx with MRT 2.0 and I get a sound at 42-45 mph that sounds like a heart shield vibration. Everything seems solid underneath. If my stock mufflers are removed then where the heck is the vibration? I assume it would be worthless taking it in for service since the tsb wouldn't apply to me with an aftermarket axle back.
