[6pack] Strange vibration

[Glenn Rattmann]

Sloane,
I can't comment on your specific vibration, but you did mention the 
tire situation.

Echoing John C. here; I put a set of Yoko Avid Touring-S  tires on my 
original steel wheels a while back, and it made a huge 
difference.   It eliminated the vast majority of vibrations, shimmy, 
thumping, and generally improved the handling too.  Ok-- the latter 
we might expect, merely due to new treads anyway... but I was amazed 
how much smoother and quieter the car was especially in the region of 
45-60 mph. My hubs and front suspension and u-joints are pretty much 
original, too.

If nothing else, you might more easily detect some other more subtle 
problems if you do the new tires first-- which you will do sooner or 
later, anyway.  I know there are other similar comments by listers in 
the archives.  Good luck,

--Glenn / San Diego
