2003 Toyota Tundra upper ball joint replacement

SOURCE: upper and lower ball joints

Jack the truck clear of the ground and let the wheel assembly hang. After you remove the tire place your jack under the lower control arm so it's firm. Remove the cotter pin, if you have one and loosen the big nut almost off. Wedge a "pickle fork" between the control arm and the spindle and give it a belt with a hammer until the ball joint pops. Raise the jack so you can undo the nut easily and separate the control arm and spindle.
The upper ball joint is riveted or bolted in. Grind the rivets or use a cold chisel and remove the ball joint. Clean up the area with some sandpaper, dirt , loose rust, etc.and put the new joint in. Put the spindle back on using the jack if necessary and put the nut back on and tighten.
The lower ball joint is pressed in. Tie the spindle out of the way and brace the lower control arm with some blocks or the jack if you have to. A few whacks with a hammer should pop the joint out. Clean the hole out lightly, just to remove loose rust and dirt. Put the ball joint, minus the grease fitting ,,in the hole and use the jack with a block of wood, to put it in place.You may have to fiddle with the spindle to make sure it is lined up. I've never had any trouble using a 1ton trolley jack and the weight of the truck to put the lower ball joint back in. Replace the nut and grease fitting.
The new ball joints will probably come with cotter pins, use them. Make sure the new joints are tight or they will wear the holes in the spindle. Don't forget to grease the new joints. Hope this helps.

The dealer's answer (if you are interested).......

The ball joint is pressed into the upper control arm and has a tapered stud for attachment to the steering knuckle. The ball joint stud is attached and locked into the steering knuckle using a special nut. The ball joint is a sealed-for-life type and requires no maintenance. If the ball joint is defective it will require replacement of the entire upper control arm.

Sorry.

to remove the axles, remove brake caliper and disc, remove hub assembly, the center hub/axle nut and...(there are i think 3-4 bolts on the back side of the spindle to remove the hub), you may have to force the hub off the spindle with a hammer or air hammer... once the hub is out the axle should slide out of the front differential allowing access to the ball joint nuts for removal...
