Lower Control Arm position?

98, 5.0 AWD Limited, 212k miles

I had my lower Control Arms done and since then, I have a horrid vibration intermittently. Usually from 45 -50mph than again at 65 +. It feels like a U-joint, but I think it may be the Lower Control Arm hitting on the rubber bumper.

It feels like the whole car shakes, and I feel it through the floor.

So far, in the last 6 months, I have changed, Upper CA, Lower CA, Drive shafts, end links.

I checked the bearings when I pulled the shafts and there appears to be no play. I also had the rear drive shaft checked and was told the u-joints were fine.

The LCA when sitting level, actually is hitting the damper pad, and it appears that no upward play is possible. I don't have a diagram of the front suspension, but I suspect that isn't right. The torsion bars were removed to replace the LCA, but he insisted that they are in there correctly, and in fact can only go in one way.

Here is a picture of the driver side with emphasis on the clearance between the LCA and rubber stopper.

Do you have a torsion bar front end? If so, tighten them up - that looks WAY to close.

Yes, I do. I have been afraid to adjust them, but I will try this weekend. I also know that the ARC doesn't come on anymore, so I thought that would be an issue as well.

If that doesn't work, off to the drive train specialists in Las Vegas.

Thanks.
