suspension squeak after thorough underbody wash 2015 RRS L494

[Oz Fish]

Hi all,
Gave the RRS a good under body wash, now the suspension squeaks when going over any bumps or undulations at any speed.
Has any one had this issue, and how to fix. Thank you.
PS, has air suspension, SDV6 HSE, with Dynamic.

Likely you’ve forced grit into the pivot bolts on the arms.

Tip for next time - never high pressure blast anything underneath near bushes or seals.
