I've got a bad u-joint on my front passenger side outer driveshaft. It's the heavy duty kind where you're supposed to use sockets and press it out. Any tips for this? I've had it in my vice, and soaked the joint with PB Blaster, and it just won't budge. Any other tricks to try? I've got the locks driven out, so it should just be a matter of pressing the u-joint out, but it won't budge.
