Everybody has already mentioned the bolts where the strut is connected to the knuckle.
If your guy doesn't know that, then take it somewhere else. If he finds that there is not enough there after loosening both bolts then I agree that something is bent. There may be sleeves installed in the bolt holes that would limit the adjustment range. In that case, the manual will tell you how much adjustment in degrees is possible with either one or both of these sleeves removed. The bolt hole is larger than the bolt by a considerable amount.
