After a good year I finally have a droopy driver's side door. Of course the cooler weather doesn't help. Now, someone told me that the torsion bars should never be adjusted and that new struts alone should help. What's the deal and how do I give my door a good test to see which it really needs? I don't know the age of the current struts but how long should a good pair last anyway? Tired of looking uncool at the gas station... Fil Vigil.
