Slashing water noise

[BillLumberg]

I have done research on this form and the Internet and ChatGPT, but none of them seem to have the answer. I have a slashing water noise in the back of my Grenadier. It sounds like I have a cooler half full of water making noise. I have pulled multiple drain plugs fold my floor mats up and I cannot find where I’m retaining water anywhere. Any help or advice would be greatly appreciated. Thank you.

Someone had some water trapped in a chassis rail, from memory. They removed a bunge from the chassis and it drained out. EDIT: Look here:

Not long after I picked up my vehicle in early November I noticed a sloshing sound on the RHS. My Grenadier has a safari roof leak on the opposite side , however there was water under the RHS floor rubber - which I dried , and it's remained dry since. The roof doesn't leak and I don't have the door wash "function".
I've washed the car , it sits outside in the rain and I haven't driven through a river.
Today I decided to pull a rubber plug out under the chassis rail and water poured out - maybe a litre.
I'm not entirely sure how it got in , but now it's out!

Any chance of a...

There's a service action bulletin for rear cross member water ingress - see your dealer.

To allow for the installation of a side roof awning, the roof hand rails were removed and reinserted on the LHS of the vehicle. The following day it rained and I had the sloshing water sound from the rear left of the vehicle. I found the water was located in the compartment under the car jack. I drained the compartment and had the roof hand rails removed and the area resealed, which solved the problem.

I found the chassis rail post and removed the plugs, but no water there. I think the rear cross member might be the issue from where I am hearing the noise. Calling tomorrow. Anyone had this service done? Any details?
