For about the last year or so, my Sedona has had a clunking in the rear suspension. It doesn't happen at higher speeds or on bigger bumps, but at lower speeds and on smaller bumps. Basically, I go over a bump, and there is almost a resonant 'rattle' for a second or two. Logically I would think sway bar end links, but I completely disconnected the sway bar, and the noise was still there. Seeing that the van is getting older, has some miles on it, and carries a decent load every day, I've been freshening up some parts lately:
-The main rear control arms had cracks in the bushings (not too bad), so I decided to replace those since they're easy and pretty cheap.
-The rear shock absorbers looked fine, but are even cheaper and easier than the control arms, so I put on 2 new KYB Excel-G shocks.
-Sway bar links are even cheaper and easier yet, so I did those too.
Long story short, the noise is still there! Everything on the underside looks fine. The rear trailing arm bushings are good, no cracks. The toe links look fine, secondary control arms look fine, sway bar mounting bushings are fine. All heat shields are in place, exhaust hangers are intact, etc. Everything on the inside of the van is held down tight, rear seats are removed so those can't make noise. The rear hatch and latch assembly are tight, the rear condenser unit for the A/C is securely fastened, etc...
Whatever is making the noise sounds substantial, either in weight/size. Could one of the toe link arm ball joints be bad? The boots look fine, but maybe there is play within the joint that I cant see. Any ideas? Van rides great otherwise, and is nice and tight after the new parts I put on.
