POR-15 was used on the a-arms. I had to reuse the original shafts. The shafts I prepared with the suburban arms won't work. The POR is too thick to slide the new bushing over. The picture above displays how I removed the original shafts. I drilled out the rubber bushing on both sides, then slid the shaft out.
So WARNING...use only POR15 on the inner portion of the shaft and nothing else. If you use POR15 on anything like threads or the anthing you need to press, you will have a hard time using the part again. The frame, fenders, firewall, and everything else will have Zero-Rust instead of POR15. ZeroRust is basically the same but it lasts longer.
I'll post a picture of the damaged a-arm. The a-arm was damaged going 70 MPH on some back road. The groves were very deep from semitrucks.

I taped plastic sheets on the concrete floor. The entire truck is sitting over plastic. The kitty litter has helped reduce the mess on the floor. The litter has collected oil, coolant, trasmission oil and even all the water from pressure washing. There is almost no runout of contaminates from the garage. Good thing because the street drain directly in front of my house has a no dumping sign. All the water goes into a pond on the backside of my neighborhood. You can catch small fish and see an occasional turtle.
