Every time I start my car, I get a strange rubber-on-rubber sounding squeak from the vibration of the engine. From what I have heard, the mounts are hydraulic. Is that correct? If so, I should be able to see fluid leaking from it, right? If I have diagnosed the issue correctly, how difficult is it to swap in a new motor mount on my own? Thanks! Note- The car has just over 75k miles on it now, and that means I have unfortunately surpassed my extended warranty. Not sure it would have been covered anyways though.
