The Stovebolt Site Forums The Parking Lot Tons 'o Fun U Joints

I second using the balljoint (probably a spell-check glitch Glenn) clamp/press for u-joints. It's way better than the neanderthal hammer and socket method. I bought one of those a number of years ago and even use it for ball joints.
That Spicer catalog link is a good resource, too. I've saved a few of the items from there on my computer for reference.
