Go to a garage that can balance the tires while they are still attached
to the car. This should cure your problem.
<<<<Okay, I have a 2001 Hyundai Accent and just had the alignment and
balancing completed after the garage said that would fix the problem.
This has been an on-going problem since mile 80,000 and it's still here
at mile 102,000. Here's what's going on, as I accelerate all is good
until speeds around 65-75 then it will shimmy something fierce the
harder I push down on the accelerator. If I'm below or above and
accelerating I have no problems. Also if I let off the gas around 80
and let it coast down there's no vibration. The dealer was not helpful
with this at all. Any input appreciated, as my warranty is now null
and void, so time for me to play and stop paying $75/hr. Thanks in
