I so I've never driver my car with no radio, no ac before. But the other day I was just taking a short ride down the street and had everything off and i noticed the smallest tiniest creaking in the front suspension. Remember i just did lowering springs, So of course I Got it up on stands, rechecked everything and it was all good. When I lowered the car with the jack in the front, (creeeaak). So i googled it, and found A TSB for front lower control arms producing a creaking sound when suspension travels. Could I just lube these bushings? Its not loud at all but i would prefer that there was absolutely no noise. Or do I need to just go aftermarket? tubular, poly bushings?
I found the TSB and its only a 1.6hr job.
