Like the title says ...
I recently installed Yoko Avids that were force balanced and a complete alignment was performed by a reputable alignment shop (White Wheel Alignment in Cleveland). I called the shop right away and they told me that it could be the rotors or the wheel bearings. They are going to road balance them again, but the numbers on all tires were extremely good.
I had a similar shimmy issue on my 04' GTO that was cured after I replaced the front rotors.
Any suggestions??

Loose tie rod ends might be a cause of this.

They completely checked the suspension and found that my stabilizer links (I think ... don't have the receipt with me here) were worn. I had them replace them with OEM ones. I also had my rear shocks and my front struts replaced with Monroes, but all the mounting hardware was AC Delco.

mine did that too. Around 70mph it shaked pretty bad until about 90mph. It was the tires all around and one rim was bent which didn't help. I replaced the stock tires with a set of Falken ZE329, a very nice tire. The shop also said I needed rear shocks and the compressor for the shocks was bad. So, I got those and it's smooth driving ever since.

I had all that work done because I'm trying to catch up with the maintenance and I still have the shimmy ...

Jack the car up, grab each wheel at 6 and 12 o'clock and see if there is any play. Also, make sure both stabilizer links are tightened all the way. I had put new ones on a week ago and didn't know how far to tighten them. We went about 40 miles to the drive-in that night and I had the shimmy at and over 70mph. I tightened them all the way down until I ran out of threads this morning. The car didn't shake at all today going about 20 miles to a party. Almost all of it was between 70-75mph, so it's worth double checking those.

My shimmy is exactly at 70-75mph and the stabilizer links were recently replaced ... I will have my mechanic go over the suspension in a few days.

The alignment shop told me that one of my tires is out of round. The road force balance numbers on the bad tire was 29. The other three tires were 4, 6, and 14. They placed the two tires with the lowest numbers in the front and the worst tires in the back. I drove the car to Detroit yesterday and I could still feel the shimmy, but it was more of the entire car shaking rather than my steering wheel. Called Tire Rack and they are sending me a new tire.
This is the second time I have had an issue with a out-of-round tire ever since I've been force balancing my tires. I wonder how many bad tires I have had in the past ...

Just got back the car again from the shop.
My shimmy is not completely gone, but it's 90% better and the entire car doesn't shake like before. My mechanic went over everything and found these two things ...
1. One new tire was somewhat out-of-round
2. One rear rotor was out-of balance ... this contributed to most of my shimmy.
I'm gonna try to tighten the stabilizer links more to see what happens ... are these supposed to be tightened to a specific torque or can they be bottomed out like someone mentioned in a previous post??
Thanks,
G

Good to know its fixed, but another possibility for someone else in the future is: bent rim.

My shimmy seemed to be almost gone, but it came back like before. The weird thing is that I was washing the rora yesterday and cleaned my rims with a pressure washer. I cleaned the inside of the rims really well with the washer. I noticed that my vibration has decreased since this wash ...
Is it possible that my rotors are somewhat rusty and the pressure washer took the "extra" rust out making the shake less noticeable? Or maybe my hubs are going bad?
I kinda feel my shake is not constant, but it might be because the different types of roads around here.
Any comments?

funny you should say that b/c as silly as it sounds it happened to me once in my mustang. i drove down a freshly repaved/graveled road. the sticky gravel collected up in spots on the back side of my wheels and made the whole car shake. i jacked it up, took a putty knife and knocked off the oil stuck gravel and the shimmy went away. drove down any freshly repaved roads lately?
