Hi,
   Saw a recent post mentioning Wurth  saBesto HHS 2000 as a fix for a noisy
speedo head.  I ordered some from Amazon.com.  Yesterday I was under my
vanagon, doing my pre-journey inspection and maintence and I took the HHS
2000 under there with me while I was checking and changing oil, etc.  I
sprayed it onto my shift linkage and all the front moving parts I could find
like sway bar bushings, etc...   My shifting is now wonderful!   Not long
ago, I replaced all the parts in the linkage and have kept them greased and
lubed, but they've never been what I would call 'buttery smooth" because, I
suppose, of all the bushings, rods, distance and angles involved...Now, it's
shifting like a dream!

  And the front end seems to function smoother as well.  I understand this
stuff is often used by race teams on suspensions, and I can see why.  A bit
more expensive than WD or silicone...but an order of magnitude more
effective in making things slide...
