Now I turn attention to the trailing arms.
After burning out the old worn bushings, I flap wheel the inside surface with a dremel.
Wire wheel the surface of the trailing arm to prep for paint:
And then acid etch with phosphoric acid:
I also etched parts of the undercarriage:
After some POR-15 on the trailing arms, they turn out fantastic. The surface is very durable. I can strike with a hammer and it bounces off the POR with no damage.
Subframe looks great as well:
Now it is time to work on the Subframe's trailing arm boxes. I ordered Ireland Engineering's "Positive Lock" Camber and Toe adjusters. Honestly I am not too impressed with Ireland Engineering's customer service. These were on backorder for a long time. However, these are well made pieces but are very costly. Here is what your receive:
Now I level the subframe:
And I start the mockup process:
Now I use cardboard engineering and make templates that will reinforce the camber and toe plates:
Transfer the templates to good old
American Steel! I use white out and lay out where I need to grind in preparation for welding:
