Hello, George. I've tried that too, but it doesn't make any difference. I'm going to lift it tomorrow and check for a defective tie rod, although I have a hard time believing that would be speed dependent.

It's good to hear from you, though. Are you still cranking out those shifters? I still say that's the best mod for the money on the L99.

If it does it in neutral as well I wouldn't think it's drivetrain related although it is possible.

I still sell the shifters, it seems most like the pistolgrip although I still have some who dragrace who like the original shifter as it can be fitted with various switches for linelock, nitrous etc. I still use my original one myself.

PROBLEM SOLVED!



Well, it turns out JusticePete and I were both correct.

The wheel/tire package was in balance (verified again on two different Hunter road force machines), but apparently the hub/rotor assembly was not. I finally solved the problem by rebalancing the wheels while they were mounted on the car to compensate for the problem in what turned out to be the front left hub assembly.

Using the current weights on the wheels as the 12 O'clock position, I added a 1/4-ounce weight to the already-balanced wheel at that position and moved it around the clock. I road-tested the car after each movement until the vibration finally improved at the 8 O'clock position. Then I added another 1/4-ounce weight at that position, and the vibration disappeared completely.

Thanks to everyone for your suggestions, and if there are other people out there with the same problem, you might want to give this a try.

I forgot to mention that if you do end up balancing the wheel while it is on the car, you'll need to mark a stud and hole if you remove the wheel. This way, you can remount the wheel properly on the hub assembly again.

I'm experiencing the exact same issue. Had the tires balanced countless times to no avail. But re-alignment seems to have made the vibration less noticeable. I'm right above 23k miles

My car vibrates consistently above 60 mph and I have had them road force balance twice now, last one being today and I still have the vibrations in the steering wheel. would you suggest getting them balanced while still on the car as well?

I've gone through 3 sets of tires and 2 sets of wheels to no avail. I've tried road-force balancing, and it doesn't make a bit of difference. It's not the drive shaft because the vibration is completely speed dependent, regardless of RPM. And it's not the rotors. The brakes are smooth as silk.

It has to be in the steering or suspension. I welcome any and all theories at this point.
Hello I have the same issue, had balancing done 4 times and new set of tires and rims and front end check by tuffy but I didnt give up , have a friend 30yr mechanic found my problem and it is passenger front control arm, the bushing was shot, ORDER a new one will install on saturday

Kevin,
Your story reminds me of an old balance shop that was at Long Beach airport long ago. While getting ready to assemble my Pitts IO-360, I had him balance all the rotating and reciprocating parts.

But back to your issue, I still think you may have a slightly out of spec runout of that front hub, which causes you to get better results when balanced as an assembly. Change that hub and I’ll bet you’ll not have to balance as an assembly.
