Strange Tire wear on GY 399A Steers

On 7-6-2013 we brought our 2007 FL C120 in due to some irregular tire wear and a slight shack in steering. They said it was the kingpins, so we had the kingpins, tie rod, wheel hub, 3 axle alignment and then put on some new GY 399a 295/75r22.5. About a month later we started to see the tire wear shown in these pics. If you face the tire and look at it like a clock, the wear only goes from 12 - 5 from 5 - 12 the tire is wearing perfectly. We brought it back in and the said the had now idea what would cause this, they redid the alignment, but the wheel would not center due to the Tie rod being installed incorrectly so they redid the tire rod. Not to mention, they then "realized" we needed a whole new brake system, but that is a different story. So has anyone else seem this kind of wear and what could it be from. There only suggestion they had was it could be the rear leaf spring bushings and they wanted to install four new rear springs for 4K, but this is on the steer tires and the drive tires are wearing fine.

 

Yes they were balanced again at the end of Dec.

 

To be honest I am not sure. They balanced them when we put them on, on 7-6-13, then they told use they did it again on 12-29-2013, when we brought it back in. It was done at the TA.

 

Well I talked to GY and they said to call Wingfoot (who handles their stuff in my area), WF told me to bring it up but, from what I described they think this is a known issue that GY's warranty does not cover it. GY's normal position on this is to just live with it, but he said that since this happened so quick that they will see if there is anything they can do.
