So Its been about 3 to 4 weeks and I just cant figure out why my car is shaking so Bad.. My Steering Moves Left to Right and it feel as if the weights in my rims are totally off...
I have done

Road Force Balance
New Tie Rods
New balljoints
Alignment
I have HKS Hypermax Coils
New control Arm Bushings

I have even swapped out my 20s to my 17s in the front to see if that was the problem... Still It vibrates Vigorously... Im FED up.....

When i went to do the alignment my friend looked over everything and said everything was Tight....

Welcome to my hell...

I have a second Gen GS with wheel shimmy that has caused me more greys than my divorce did.

Are your wheels hub centric?

Emil

new steering bushes next i'd say,and tighten up the rack

Debonair

Check your rotors for runout.

whats RUN out... ???

Emil

new brake disc's i believe?

Debonair

This is my simplified explanation: Runout is when the rotor is not the same thickness or flatness all the way around. Its also known as being warped. This, along with out of spec (too thin) rotors can cause vibration as well. Usually you will feel pulsing in the brake pad when there is severe runout.

Did you tired check the front wheel bearings? You can do that by raising the car up and move the wheel up and down see if there is freeplay.

steering rack bushing, adjusted rack, hubrings woud be your last resort.... or maybe an bad knuckle who knows...

gs4004gs

I have to admit, my shaking is only from 55-65mph. Does yours go away if you go fast enough?

I was going to say maybe a bad belt in the tire or an out of round tire but I imagine a road force balance would catch that. Same goes for a rim with a wobble in it.

I've had my front end looked at several times, each time with a "It's tight!" or similar reply. My wheels have been balanced so many times I think they've spent more time off the car than on.

Some guys report tightening up the pre-tension on the rack helps but that's kind of just hiding whatever the real issue is.

this could be it..I resurfaced my rotors at the beg of this year..... but can it make it vibrate really BAD... and my wheel bearings are good from what the guy said when i went to do an alignment...

GS300ToM

rotors being warped only effects when stopping not accelerating...bent wheels, off balance, tired bubble (defective) or suspension cause shakes...

but keep in mind... find the run out or parellelism to see if anything is wrong with your hubs...

thats what i was told by my teacher and try the rack method with someone in the car and steer left and right to see if your rack moves...

Debonair

Although I have not experienced it I have been told about and read cases of elusive rolling vibration caused by runout AND/OR out of spec rotors. It makes sense. If there is more material on one side then the other it will not be balanced and can cause some vibration. Just one more thing for him to check. He already stated he gets braking vibration which is not normal.

OP - you can also try throwing your stock struts and springs back in the front to see if it continues. You basically need to start ruling things out one by one.
