Tires have sufficient meat, new upper ball joints and tie rod ends, and
it's coming from the rear somewhere, anyway. Seems to be below about
where the rear bench seat's kickpanel hits the floor. I've recently
replaced the rear outer wheel bearings and repacked the rear axles... it
was making this noise before any repairs.
It sounds... well, if you've ever dropped a dry 2x4 on concrete and had
it vibrate before settling down, then speed up that noise and raise the
pitch slightly. Sorry, but that's the only thing that reminds me of this
noise.
Should I have replaced the lower ball joints as well? The boots seem
fine, and there wasn't any play.
