I am on my second pair for both my '03 and my wife's '04. In both cases, the struts started failing when the weather turned cold. In fact the second set on both trucks is starting to show the same signs. I bought Strong Arms for my truck (from an aftermarket source, don't remember who though) and MOPAR replacements (from moparpartsamerica.com) for my wife's truck. They look like the exact same thing, but the odd thing is that both the factory and replacement struts seemed to last longer on my truck than hers. We both have the same grille insert too. It is irritating because when they stop working as they should, they give no warning. Both my wife and I have nearly been hit on the head several times by the hood falling back down on its own. I wrote an e-mail to D/C to complain about it and they were going to send a rep out to look at problem till they found out that I had already replaced them and thrown the old ones away. Silly me for not wanting to get a concussion from trying to plug in my engine block heater!
