I just broke one og the Universal Joint (connecting the diff and the wheel, not the drive shaft one) in my Spitfire Mk3, I am running on Hayabusa motor.

When I removed it it was broken i 2 pc and it was fairly easy to remove the part of the UJ from the diff flange, but the one on the axle to the wheelhub, is not so easy. How should it be removed? I tried to give it a small knock but is does not move. I dont want to destroy anything inside the wheel hub, so I desided to seek advice from you guys on this topic.

Thanks,

If you don't want to remove the entire axle from the car you can use a 3inch C clamp instead of the vise in the above video.
If you are running more torque and horsepower than stock I suggest a solid/permanently lubed "U" joint. They are stronger than the ones with grease nipples and replace the U joint on other axle while you are under the car.
