To Len Alanurm, the owner of the 1980 Toyota Celica with the vibration
problem:

   I have posted the reply to Usenet because the answer to your  prob-
lem may help others.

   You say that you have balanced your tires and swapped them with  no
luck.  You can balance a square block, but it won't ride smoothly!   I
am willing to bet that your Michilin (sp?) tires are out-of-round.   I
have experienced this problem with Michilins and Uniroyal tires.  I am
assuming that you have already checked the other obvious  items,  such
as worn or missing suspension parts.  In my experience, the  vibration
caused by slightly out-of-round tires occurs between 50-60 mph. Find a
good tire shop somewhere that has a machine that will check to see how
round your tires really are.  I suspect that you will find one or more
tires are out of round.  This has been a problem lately, and  I  think
it is caused by a lack of quality control when the tire was made.

   If the tires are indeed out of round, this can be  corrected  on  a
special machine for only $20-30.

   I hope this will help you and others on the net, and good luck! Let
me know if this works out.

                               Dennis
