Suspension squeaking

So, about a year ago, I noticed my suspension was squeaking when I would go over a bump or even if I got on the back bumper and made the suspension move at all. I took it to the dealer and they said "There is a recall" on it, so they fixed it. About 5 months later, it started squeaking again. I haven't taken it back yet because it's been winter and I haven't had the windows down and haven't noticed it as much. But since it warmed up a little I've been riding with the windows down and I notice it when going down a dirt road. Would this be covered in the TSB? What about if I'm at 57K miles?

Thanks.

 

There was a TSB for squeaking from the rear. The fix was to put grease between the leaf springs at the ends where they rub against each other as the suspension goes up and down. I think it was 3yrs or 36k for the warranty.
