That’s good news then,Looked at that side and the spring looks new?!shiny black paint on there.
Possibly sticky top mount bearing after being stood maybe try lock to lock on the steering & see if it does it , mine does it after heavy rainfall etc.
Check battery age if Varta there should be a date stamp on the terminals
(Mine was 17 years old when it failed)
Been fine since replacement .
