84 Voyager Struts

I researched the source of a 500 Hz vibration at idle, mostly in the
cab and I think I've located it as being the exhaust resonator
touching the frame.

The questions a
1. Will replacing the struts increase the clearance between the
resonator and frame.
2. Do the helical springs loose their springiness and collapse, making
the repair above ineffective.
3. How do I tell if struts are "leaking" – everything looks pretty
oily

Notes:
1. I replaced the front motor mount which was chewed up.
2. The other two motor mounts appear intact.
3. Engine size = 2.6L

Thanks for your help.

Are you refering to the catylitic convertor hitting the k frame on accel?
Causing this noise? And does it not do it in reverse?

clean up the struts. Drive around for a while. Then check the strut
again. If it is oil, it is probably leaking.
