Well, shit. Now I am concerned about the bolts too. Ugh, looks like the wheels will come off once again. Lol. The bolts did tighten down good though.I can't remember where I read that but when I was looking up the bolt part numbers on Ford parts websites, they say "one time use" or "do not reuse". Something along those lines. I did notice that the originals appeared to have blue Locktite on them so maybe that's the reason? I'm definitely replacing mine. Should have the new ones today. It's too cheap not to, to have that extra insurance IMO. That said, I would probably at least add some more locktite to them to be safe.
What concerned me was that I actually snapped one of the factory bolts, trying to get them off. It was one of the smaller ones (I think 14mm) that hold that caliper/piston to the assembly in the rear. Luckily I was able to back out the broken part without too much issue.That's what got me going down the road of replacing them anyway.
EDIT: Here are the bolt numbers for your information:
Front: W716471S439
Rear: W715623S439 (I believe these are the larger 18mm that hold the assembly to the rotor)
FR3Z2C150C (These are the smaller 14mm (I think) bolts that hold the piston to the assembly (and one that I snapped))
