I think the main pivot bearing needs replacing on the bike, is it a big job, or best done at the local shop ?

if its the one behind the bb i believe its a dealer only tool as its a bitch to get out, call your local spesh dealer and ask
i've got a 2007 sj and i think after this winter ill prolly need to look at getting it done so post up how you get on
I used to have an 07 stumpjumper (now have 08) and had several bearing replacements, I've just replaced them on a giant anthem (fairly similar) and with a few blocks of wood, a hammer and a bit of time it was dead easy to do. The chainstay bearings (near the rear axle) are definately a shop job though.
It is worth prising off the bearing covers every now and then and purging the grease through, should prolong the life of the bearings a bit.
