Rear derailleurs really take a beating. Exposed and hanging off to one side on the back of the bike they just seem to beg rocks to lean over and give them a kiss at 25 mph. If you have a derailleur that is a little loose and is kissing every rock in town, it's time to kick it to the curb and get a new one. Shimano Deore M591 9-Speed Rear Derailleurs offer low maintenance and reliable performance that won't cost you a pretty penny. The SGS long cage derailleur swings well with wide range cassettes and triple chainrings maintaining good chain tension when you are in the small ring. As one friend speaking to another, you deserve better shifting. Dump that ratty old derailleur and get a tight new Shimano Deore M591 9-Speed Rear Derailleur.
