Bad Ball Joints Again.

Bad Ball Joints Again.

After breaking a second axle U joint in just a few months time, I had to see what was wrong. While I still don’t really understand why, I know from experience that if the ball joints are loose, the U joints will break.

As I was putting the hub back in after changing the axle shaft, I saw the ball joint move. There should be zero up and down motion in the ball joints. They should only pivot. Mine was moving up and down almost a quarter of an inch. I knew this was trouble so I removed the axle shaft and replaced it with a 2wd stub shaft to wait until new ball joints arrived.

With the new ball joints in hand, I set about removing the old ones. They have only been in pace a couple of years or so. I followed the same procedure I have documented before in: Ball Joint Replacement.

When I went to separate the knuckle from the ball joints, the lower joint split and part came out with the knuckle and part stayed in the axle. I had found my problem. I am still not sure if it was a bad part or was not lubricated properly.

I pressed in the new ball joints using the same procedure described in: Ball Joint Replacement. To reduce stress on my press, I used a hammer to strike the end of the press between turns on the bolts. This trick allowed the press to easily push in the new joints without bending the press as I have done in the past.

The hammer taps help to keep the ball joint aligned as it presses in and relieves and sticking as it moves through the axle. Hammering also helps in the removal process as well.
