I was looking under my van yesterday and noticed shinny rubb marks on both
drive shaft axles where they pass through the trailing arms.  This definitely
is not supposed to be happening!  I have been unable to tell what part of the
trailing arm is making contact.  Has anybody else encountered this?  My
apologies if this has been covered in the archives, but I don't currently have
browser access.  The dirvers side axle has a 1/8" wide score and the passenger
side axle has a 1/2" wide score around it.
  The only unusual thing I've done lately is had the back of the van hike up
about 6 inches while attempting to break free locked up parking brakes.
Btw, I repalced the rear shoes 3 weeks ago and I am still having the parking
brake lock up after it rains (and rain doesn't seem to stop this year).
  Any input re the axles would be appreciated, I don't like the idea of them
breaking!

Thanks,
