Those pistons could be considered wear items what happens at the dealer will depend on how the two of you get along. They start to wear out as debris gets into seals and cold just makes it worse. For the record the ones on my old wagon went 10 years before I had to change.

Good news is they aren't stupid expensive and are an off the shelf item at places like Crappy Tire. I's an easy DIY job and the trick is to change one at a time not both at once. ;)

I have to say I am shocked to hear your wing is 40lbs! Is that true?
