Swapping Starter
 

Does anyone here know how to swap the starter? Is it something that can easily be done at home or should I take it to a garage?

It's not too hard on the 3400... It's held in with two bolts and has two wires bolted to it as well.

is it fairly accessible?

its actually 3 bolts if i remember correctly, just follow the line off of the battery that goes to the starter to find it, once you find it, its pretty easy to do, the only problem that i had was putting the new one in cause my hands are big and its in an awkward spot, good luck
