I just placed my order for the Monroe Quick Strut's for the rear of my '03 Explorer. $255.75 for two quick struts and shipping. Of course they say it will ship between the 21st and 22nd, but they won't be delivered until next week.
Hopefully it will be sooner. Though if they do come this week, it's supposed to rain every day and I don't have a garage to put the truck in to work on it.
Will let you know what they're like, and how hard they'll be to replace.
Thanks for all the great info so far, glad I found the forum otherwise I'd be looking at going to a shop or worse the dealer to get these replaced.
