Cool! People actually use my DIY's. Thanks, glad to see it.

Ideally, you'd use a bearing press with the whole hub assembly and brake line removed from the car, but I used the 2 welding clamps to press it in so I wouldn't have to do all that. That's way too much work. I was just being creative.

Without them... 2 pairs of big channel locks and brute force? A block of wood (to keep from damaging the new ball joint) and a hammer (this really doesn't work well if you're impatient)? Maybe a LARGE deep socket and a 10" C-clamp? It's a tight fit, and leverage is key. You need equal pressure across the back face of the ball joint or it will bind and get stuck.

Those are snap-ring pliers. There's a ring that goes around the bottom of the ball joint that fits inside a groove to hold it in place. You have to remove it to get the ball joint out, and install it after the new one goes in. These pliers have pins on the end that fit in holes on the snap ring. Once in place, squeezing these pliers spreads the ring open enough to remove it from the groove. These pliers are really cheap.

Nah. Not necessary. Your hubs have sealed bearings. If you see grease on it, it's probably from a previous axle failure. That's why I ripped that hub apart to begin with.

If you visit www.harborfreight.com, you can find all of these tools REALLY CHEAP!!!!. Advance, Pep Boys, AutoZone and Nappa will all sell them, too. Probably not the welding clamps, but those should be easy to find elsewhere.
