1998 Safari Conversion Van.......?

To me, that sounds like worn shock absorbers or worn out McPherson Struts, if your model has them instead of shocks.
 
Might be something else, though.

 
       Are the shocks standard or the struts?  Or both?  I'll have someone take a look.  I miss the days I could slide under vehicles to have a look/see.  Mostly looking for drips...I didn't always need to crawl under a car to find a DRIP or a JERK 

 The last time I did that was when I had a "emergency Christian" moment.  I took a coat hanger to wire up the whole exaust system on the Ranger when it fell off going down the road.  All except where it bolted to the engine had dropped.  
     
My prayer was  
If you're up there and paying attention...PLEASE LET ME BE ABLE TO GET UP OFF THIS ROAD"  and I did!
