My delivery got delayed, but I got the new Cardone box swapped out with my previous Bluetop box today.
Arrived from RA just as should be. 6 bolt. Everything bolted right into place. Just did a quick trip down the road, but seems like a significant change in the reaction and smoothness of the steering. I also added a inline filter and went with Amsoil PS fluid. Flushed the system with what I had left of some Prestone PS fluid first, then did a flush with the Amsoil.
Two notes. It seemed the pitman arm got "snug" on the shaft quicker than previous boxes. Also seems that there's a slight height difference from where the pitman rests compared to before. But I can't be certain. I'll get an alignment done and that should tell the story if my toe in/out is off.
