Rattle under Expy

[Rcalvin]

I seem to have a rattle under my 2017 Expy. Sounds like something is loose. I’ve been under it and I don’t find anything loose. Anybody experiencing this? 3rd Gen.

When does said rattle generally occur? Parked, in gear, or under way?

 

[Rcalvin]

Underway driving down my driveway slowly. Backing out or the garage. It’s not the exhaust. Expy has 50,000 miles on it. Spare is type. Just had it aligned and guy never said anything was loose or wore out. Puzzling.

Heat shields, brakes? You have to get outside and listen while someone backs it out, or get under it while someone jounces it.

I got under the rear while my family pushed up and down on the rear and the noise is coming from the top of the rear shock tower. Nut is tight on both left and right Shocks.

Shock mount bad or possibly that shock.
