I had the same problem with my trek 4300 that I bought used...I replaced the derailure and that didnt fix it...turns out the cassette was worn out because the guy who rode it before me apparently got a lot of use out of it before he sold it....wound up replacing the cassette aswell and the chain (because everyone says when you replace the cassette you have to replace the chain) and it runs smooth an quiet now. I think if you replace your chain and cassette everything will be fine. You can also find some pretty good cassettes for a reasonable price if you shop around.
Funny thing. Not a week after I replaced the chain, derailure and, cassette, my cranks started to work loose and I had to replace those too. So essentially I have put an entirely new drive system on this bike. It was worth it though because I got the bike for $120 anyway and even the parts and labor I have put into it dont equal what a new mtn bike of similar quality would cost.
