It is most definately dangerous.
They can go bad.
Most definitely.
bad rear swing arm bushings on some you can tighten
bad trailing arms or bushings,or bad struts!!
Could be a bad shock absorber or shock absorber bushing. Could be bad bushings on the rear sway bar (if equipped).
The trailing arms are what holds the rear end/axel on. The bushings are what allow movement of the arms.
could be the rear strut bushings are bad.
Worn out shocks perhaps. Could be bad suspension bushings too.
Since The Villager is of unibody construction, there are only a couple things that can be considered "subframe bushings". Sway bar bushings (front and rear), rear leaf spring bushings, and the most likely, control arm bushings.
When your rear trailing arm (rear control arm) are bad you will hear a clunking noise when going over bumps and potholes .... This noise is louder and more noticible while you have passengers in the rear seats..... You will also hear your tires squeek a little on turns
