Honestly- this type of repair can quickly turn into a major suspension overhaul. The rust in the photo doesn't look too bad, so unless you want to remove the a-arms (which MIGHT mean replacing the bushings, sway-bar bushings, drop-ling bushings, maybe shocks, etc.), I would just sand them down a little to see how deep the rust is. If then you decide to repaint/powdercoat- then they will need to come off to do it right. The job is not too difficult, just takes time- and the part cost can add up quickly if you start replacing things because you are there and they are already 20 years old. I'm not versed on the 512 (I wish I was!), my experience is with the 308 series, but I assume the basics are the same.Boxer said:Recently I noticed a bit of surface rust on the lower arms of the rear suspension on the 512BB. Any suggestion on the best way to get rid of this ?
