    OK, I've installed my new OME suspension. (See http://www.tacomaworld.com/forum/su...talls-full-ome-kit-rear-brake-lines-pics.html)

    I've got a fairly loud ka-thunk when going over bumps. I can rattle it pretty good at low speed on some parking lot speed bumps.;)

    I'm pretty good at diagnostics, usually.

    So, what are the questions I should be asking myself in order to narrow down what the problem might be?

    for example:

    front or rear?
    left or right?
    noise on compression or rebound? (though actually, I'm not sure I can tell that one)

    Then, what are some likely causes, and how can I test for them?
