Bottom Bracket Problem on Trek 4900

[goldzzz14]

I am going to completely rebuild my 2003 trek 4900 because I just destroyed all of the components on it. the only things I will not replace are the frame, stem, and handle bars

also watch plenty of your tube videos on bike repair.. a few are pretty helpful...

for example

I like the vid by leonardmlee on rear derailleur tuning.. its perfectly explained and the derailleur on my trek 4900 working perfectly...

you need to replace bottom bracket dude.. you might even want to get a whole new crankset or upgrade to nicer 2 piece one...Get a book on bike repair from a store or library, then get the few necessary tools to replace bottom bracket.. Its cheaper than goin to a mechanic and then you'll always have the tools.. and know how..
