I recently acquired a 1994 Caravan (3.3L 3spd auto w/O.D.). It behaved very
badly on bumps, sounding like it is bottoming out on what seem like small bumps,
producing a very loud "thunk" from whichever front tires that hits the bump. My
previous van (1987 Nissan) never behaved this way.

The records I have show the following:

Current mileage 128,600
Struts replaced @ 93245
Motor mounts - Cntr Eng, replaced @ 120,093
Sway bar bushings replaced @ 120,093
Outer motor mounts appear to have been replaced also

It seems like struts with 35,000 miles should be still good. No leakage is
visable.

Can anyone offer any suggestions to solve this problem? New struts? stiffer
struts? Anything?
