One of the front ball joints on our 2010 E350 has worn after 90k miles. Have ordered four Lemforder arms which just come with the nut for the ball joint. Ordered four new bolt sets and cups. They are described as A0003330971 camber/caster correction bolts. The last time it went in for an alignment they didn’t want to touch the camber or caster as their system said it wasn’t adjustable. With these new bolts will it be possible for them to set the camber and caster correctly or am I missing something?
