Does anyone have pointers on how to remove rotors that have rusted onto the hub? I tried dousing the seams with PB Blaster Spray and whacking it with a rubber mallet and they won’t budge. The car is a 2001 Ford Focus, so it doesn't have those screws that some of the japanese cars tend to have.

Pretty much. That's fairly common on Fords (and a number of other makes). 5lb mallet, some spray, and a strong arm. There's a number of vids out there on other tips/tricks. Good luck!

I recently replaced front rotors on a 2008 Ford Fusion. They would not budge after PB Blaster and mild banging. I didn't have a heavy hammer. So I had to use my normal hammer and repeatedly pounded the rotor from the inside as my son rotated the hub. It took a bunch of hits to work it all the way off.

I asked a friend who does this stuff all the time how he does it and he said he uses a BFH.

Pretty much what everyone else said. Bigger hammer, more spray. Work it side-to-side, don't just keep hitting the same spot over and over.

You might try to heat the rotor a bit as well.... Last time I had this happen I used a plumbers torch, pb blaster and hit the rotor with a 5lb sledge with a dead head 3-4 dozen times. Once it was off, I sanded some of the corrosion on the hub down, applied a tiny bit of anti seize paste when the new ones were put on. Dont know if it helped or not but figured it couldnt hurt.

Another thing to try is to wedge a metal bar (socket extension or pipe) between the rotor and a rigid part of the frame if possible; then use the power steering to break the rotor free. I don''t know how feasible this is on a focus, you may not have a solid location to wedge the bar and you also run the risk of separating the bearing hub depending on the design (most likely not though). I use this technique when I can with great success. Best part is you don't even break a sweat.

Heat is another option but you may end up melting the seals in the hub.

I had that problem with my caravan, could only find a framing hammer, and nothing. Finally found the B.F.H. two good whacks and it was off.
