I have an 06 with 54k on it. Running everything stock except for H&R springs and 12mm spacers all around. When the car is cold and sometimes on bumps like comming out of my driveway there is a loud squeak that comes from the rear and sometimes on bumps it happens as well. Have not checked my shocks to see if they are leaking yet but am I right to think that this is the symptom? If this is the case sounds like Im going to just jump on a set of coils like I should have in the first place. Thanks in advance.
