Front vibration through steering

[Cloudsurfer]

Already replaced the control arm and outer tie rod ends (both sides). I find it hard to believe, but I really am leaning to thinking there is damage to the hub/ hub carrier/ bearing.

Yesterday I took the box down to discount tire to have them dynamically balance the wheels and use the Hunter 9700 road force process to insure the heaviest part of the wheel was matched with the lightest part of the tire to get the best fit.

This was done when I bought the wheels and tires, but not done since. My fronts were close enough to correct with weights. My rears, however, had moved 14 inches and had to be knocked off the rim and rotated around more than a foot so they'd line up again. Obviously, the weight of the motor and the force of hard acceleration and braking moved them a fraction of an inch many many times.

I still have some vibration up front though... so bearings are my next issue. I would imagine that your front end vibration is coming from a wheel bearing if you've had your front wheels dynamically balanced and road force balanced.

I doubt it's the wheel carrier itself. I've seen one torn down and everything bolts onto it nice and tight.

Sometimes you just get a bad tire that is slightly out of round or has a delam. internally that no one can see. That should get picked up on a careful wheel balance though.

Swapped a set of factory wheels with factory tires on the car today and went for a drive. Exact same problem. The issue is not with the wheel or the tire.

I think I'm going to replace the hub/ hub carrier as thats really what I'm suspecting to be the culprit here.

OK, I can't even begin to describe the level of frustration I have with this problem. Replaced the entire hub/ hub carrier/ wheel bearing assembly today and the problem has not changed.

So, to recap, we have replaced

1) Front control arms
2) Inner and outer tie rods
3) Springs, dampers, strut tops
4) Sway bars
5) Replaced tires on my wheels (BBS RSIIs, which are about as true as a wheel gets), balanced them 3 times. Problem existed on old tires and new.
6) Tried a set of factory wheels, same exact problem.

The only thing things that have not been replaced or swapped out now are the front thrust arms and the actual steering rack. What gives???????

I have the same problem. I have vibration at 75 MPH plus. I'm going to get the wheels balanced and I'll let you know how it turns out.

Had my wheels balanced this morning and went for a test drive. The vibration problem seems to be fixed, at least for now.
