Just bought a '99, seems reasonably good shape, and this will be my fourth bull. But I'm not that familiar with the rear suspension. There's a loud clunking coming from the right rear - sounds like a bunch of bricks or big rocks for lack of a better description. It does not necessarily follow bumps and is almost worse at lower speeds or at least I hear it more at those speeds. The rear does sag a little but peeking in the well the springs look good. Spring mounts? Could it actually be the shoes? It almost sounds like that but not to this extent, and the '04 my daughter wrecked had bad stabilizer bushings but they pretty much only rattled on bumps.
