Rep Power: 0

I have a 05 civic 2dr coupe lx. I recently put new lower controler arm bushing in new slotted and crossed drilled rotor from ebay on and a brand new set of 18' rims with new tires raptors from ebay on the car. I had the wheels balanced a 2days ago after the intital install to check balance everything ws perfect. I still have a wheel shake at 60+ i brought the car home and put it on the lift took the car up to 62mph while in the air the shaking started at 60mph im on the fence i ruled out wheel baring as it more of a womping sound and goes away when you turn in the opisote wheel direction. Im leaning towards axel shafts, centeric wheel spacers, and sugestions?

Put the old tires/wheels on. See if the problem goes away.

more than likely it will. aftermarket wheels, regardless of size, will almost never be as true as oems. the oem rims are balanced to the honda's hub and are more round compared to the stuff coming from china which could be unbalanced right out of the box.

Well, the wheel is chucked on the balancer and spun. There is a cone inserted into the center hole of the wheel that the wheel is centered on right now.
Spin it up.
One needs to watch the bead areas of the rim as it is spinning to see if they are true and have no runout (wobble).
Then watch the tread of the tire. See that there is no runout or "waddle" as it spins.
Dual-plane balance, not static balance. (If you can do a road force balance, all the better but that isn't everywhere. High dollar machines can measure and make an ideal match between the wheel and the tire.)
Repeat for all tires.

The balance job is only as good as the person doing the job.
It is easy work, but I am constantly amazed at how lazy some people can be.
I strive to do the best work I can do, while others get by with the bare minimum yet still expect the same credit.

You can balance a cube. But it won't be a smooth ride because of all the non-round parts. Same goes for a tire/wheel assembly.

Now, with the new wheels bolted on.....
Were there centering rings?
Umm, you need those. (Metal rings seem better than cheap plastic to me.) The lugs aren't supposed to do the job of centering the wheels on this car. The hubs do that job.
Remember watching the edges of the rim on the balancer while it spun?
Start the car, put it in gear, and watch the edges of the rims again....Do they all still spin true now?

Some people can feel an imbalance of less than 15 grams in a tire.

If the rims are not perfectly centered on the hubs, then you have about four 40 pound weights spinning off center and it WILL shake.
Not only can it shake because of the weight imbalance, it can shake because of not being round. Both can happen when the rims aren't centered on the hubs.
