It's M&K branch in IL, they got dealerships all over.loudtom Thanks this.

I order as many of my parts from them as possible and I don't even bother going to my local dealer for parts info. Just shoot them a email with your VIN number and what parts you're looking for. A lot of the times you get a parts diagram pdf back and its SUPER helpful.

Heat cracks, not cracked through. I can feel them with a fingernail though. Not quite to the edges of the rotor. 'Heat checking', I would say moderate, from reading some of the stuff that's been posted here. I don't think I would get shut down in an inspection but I don't like em and they're getting replaced. Pad wear is significant too.
I haven't had time this week to chase down any parts or learn more but I did find out what Volvo parts I need from my dealer. I'll post more info as soon as I have it. -
I may be able to help with part numbers, I have the Impact software in my laptop and if you still need it let me know.86scotty Thanks this.

I'm still working on this, I did get part numbers for my specific truck.
Pads are 23649812, which is made by Meritor.
Rotors are 24121370 which is ConMet. I have not been able to find anyone who can cross reference that
number to a Meritor rotor without changing the whole hub to Meritor.
