So I drove the truck for a bit today. It's only about 10 miles total to work and back, but I didn't have any squeaking. So I guess that's a plus. I'll keep an eye out for extra brake dust.
That's not why they changed. They went to a floating two piston caliper and larger rotor that provides better stopping power because the older set up was barely adequate for the weight of these trucks. Especially if used for towing. Had nothing to do with the worn slides on older models.Dodge must have made the change in the spindle design to address the problem with the notched caliper slide rails on high mile Daks.
As far as I know they are forgings.I have a MIG welder and I've thought of doing that myself. But since the slide rails are cast steel (I assume) wouldn't I have to preheat the area before welding so it doing create a brittle area on the slide rails.
