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.
