I know this topic has been a pain for many T-100 owners out there, and at least for me, I've found the fix.

For those that haven't experienced it, some T-100's have a vibration that gets worse around 65 mph. People have tried different tires, wheel, shocks, just about everything. A few years ago, I read on this site about using a Haweka adapter when the tires are balanced. My local COSTCO was the only place that had one, so I bought tires from there. It seemed to help, but as I moved away, I was unable to keep getting my tires balanced at COSTCO. I just moved back and the truck was shimmying like mad. I wondered if it was the balance, so I brought it in to COSTCO and had them use the Haweka adapter. I was disapointed when I picked it up because the techs said the balance was just a little off. However, when I drove away...

25-35-45-55-65-85.....

No Shimmy!

Hope this helps some of those out there that are deailing with this pain.
