I recently started to hear creaking noises coming from the front and rear, like when I go over a bump or slow down to a stop. Would it be the spindle nuts that I hear about? I only seen people post bout it on the rear but not the front. I'm bringing my car in tomorrow to change my softtop, what should I ask the dealer guys to do? Is there like a service bulletin or something?

Also I've always heard a lot of noises coming from the softtop, some how I feel it's louder now, am I just paranoid or is it getting loose or something?
