Ball Joints and questions

[MrCooper]

I have a few questions

1. One of my lower ball joints is starting to bleed. I need to know if you can change them or is it a situation where I have to replace the whole control arm and if I can change them is it just as simple as any other vehicle

2. I just installed a 2 1/2 inch lift and went to from OEM size to LT275/55R18. Is there any issues I should concern myself with when it comes to these oversized tires as far as the hubs.

Any help will be greatly appreicated

the ball joints need to be pressed in/out.

im on 285/70/17 and 2" with no unusual hub wear.

They can be replaced without replacing the whole control arm, but it isn't easy. My 12 ton press wouldn't budge them when I tried it.

They have to be pressed in and out. I used a small 2 ton bottle jack, the master press kit from advance auto, and a propane torch to get the old ones out. They rust/weld themselves to the bores. Get ready! They launch out with a pop and make me jump everytime.
