Washboard Rattling (1 Viewer)

When driving washboard roads there is a rattling sound coming from the engine compartment. Sounds like the ABS/booster/Master cylinder area ... right behind and left of the steering wheel.

Only occurs when driving washboard roads. Normally, tires aired down to -20psi.

Can anyone point me in the direction where the subject has been discussed?

Is your engine cover still on?

Yes

It's likely that, easy to remove and check if that's your sound.

I had a weird vibration at various times and thought it was under the hood. It was the roof rack cross bars they were slightly loosened, fwiw...
