Creaking M900 frame

I have an old Cannondale M900 Hardtail which I love. However it creaks when I’m going uphill and the frame sounds as if its about to fall apart at any moment. I pretty sure it's not coming from the components as I've tried ching most things.

I think its perhaps coming from the inserts at the seatpost and/or the bottom bracket that are creaking. Does anyone know if you can get these replaced?

    What do you mean by inserts? You could remove seat and pedal uphill to see if creaking goes- or more easily see if you can rock the crank arms by pushing and pulling the crank arm(either) towards the frame and away again, a worn bottom bracket should flex when you do this, when new they don't. Must admit never tried to replace a BB, but Park Tools guide say that it is sometimes necessary to 'face' the frame where the BB sits, this is to ensure a perfect parallel fit for the BB- they make it sound a nightmare to be fair and don't recommend doing it yourself, easy to buy though- Chain Reaction Cycles and Merlin are ace for parts, worth asking a bike shop what they charge for fitting- if you supply parts or if they can do free fitting if you buy there (may end up costing about the same). Good riding!
