Finally got around to replacing the driver’s side on the MJ. And good thing too. I noticed they were maybe a bit loose about 15,000km ago. They’ve gradually been feeling worse and worse to drive on. I didn’t expect them to be this bad, though...

When you’re changing them, you pull the hub and shaft, undo the castle nuts on the ball joints, and give the steering knuckle a whack so it drops off the ball joints, leaving the axle looking like this:

Those are the new joints. When I gave the knuckle a tap with the mallet, the knuckle slid off the upper ball joint, and the lower joint fell apart.

Thank God that didn't happen at 75 mph on a gravel road...
