After having car on a lift for a week while we fixed the engine issues, when we dropped it down and drove it noticed an annoying squeak at every bump. Checked the shocks and suspension, no failures or issues. Had my child ride in the back seat to see if we could isolate the sound.

Replaced the door pistons/ arms but this did not help. Found that it is a known issue where the body and doors are misaligned over time and the fix is to take the back of the car off and reassemble with sealer.
