Trying not to stray off topic.....but. Cam..how are you taking the axle out that you involve the seal spring? I take the outter end of the axle out of the wheel bearing then crawl under the car and hit the inside CV cup toward the outside of the car with one or two hits..it's out. I haven't damaged a seal doing it that way. And.. FWIW a 2.5" MPS pulley is perfect for installation of that seal.
