Thanks for all who replied, and yes I will be changing dealers in the future. The notch you speak of has me puzzled? According to the mechanic, he took the bottom axle side lower control arm bolts out and slid the cam bolts in? They are still in there at this moment, but I don`t see any grinder marks? And I asked him straight up if he drilled anything out and he said no.
The mount holes on your axles are square in shape and there are tabs on either side of them that can be knocked out in the event cam bolts are installed. This would allow for the square holes to become rectangular slots that will allow an adjustment in the axles position. You would NOT be able to see any of this as the cam washers would hide the slots. You would only be able to see them if the washers are removed. Did they remove the washers?
