the order to install is
the bracket is very likely needed by Rivets and Bolts to replace them to spreed out clamping force.
Otherwise the three rivets etc have Point Loads just under the heads on the arm metal. Worse if rivets bolts flange and arm itself isn't machine perfectly flat.
Then many rivets and bolts don't like joining thin CA metal because how there made. New bolts are likely running out of threads w/o thickness of all parts.
New hardware is likely Class 10.9 or better too. Softer bolts etc can fail.
Limiting steering travel is a side benefit, likely just try to limit steering if other parts fail.
Dr. Ian Malcolm: Yeah, but your scientists were so preoccupied with whether or not they could, they didn't stop to think if they should.
