The procedure depends on the vehicle and year. There is a special forked tool called a ball separator used for removal. Most auto parts will loan the tool to you.
The Impala has two bushings. One vertical which is the outer bushings, and the second one which is the horizontal (inner) bushing. Best thing to do is buy the bushings at rock auto. Vertical is like $18 and Horizontal is about $16. These bushings need to be pressed into the control arm so u have to take it to a machine shop...its probably charge 1 hour labor rate for both sides. U need a special tool to press out the old ones and insert the new ones. Removing the control arm is necessary.
Bushings need to be pressed in (and old ones may possibly need to be pressed out) with a special tool, then alignment is required to prevent premature tire wear.
For any type of bushings you will need a special tool to take them off the bushings are pressed in
There are many bushings in most vehicles. Some can be replaced easily and some require special tools and equipment. It all depends on what year, make, model and bushing you want to replace.
They are pressed in and out with a set of special tools.
You didn't say what year you have but, later models require removing the door panel, disconnecting the wire harness, removing the detent spring and drive out the two hinge pins. The spring will need a special tool to replace. You don't want to replace the hinges unless you have no choice. The original hinges are welded in to the door and the cab. They can be replaced but it is a expensive job. In most cases you can replace the hinge pins and bushings to restore the hinges back to normal. The pins and bushings are available at your local auto parts store.

Asuming you know how to remove control arm from vehicle, you need a press to push the bushings out. Rust is all most always a big problem. So a torch comes in handy. By the time you get the bushings out the holes are no longer original size. Concerns that the new bushing will stay in place become your next issue. If I was you: Find someone who sells Dorman products. They sell the complete lower control arm for about the same price as just the ball joint would cost you. 70.00 to 90.00 range. No rust to contend with. All 3 pivot points are then new.
It is the special transmission that converts engine horizontal motion to vertical rotation for the rotor
Some people use pallets for vertical gardens. Other use special shelves. You can also use hanging bags on fence posts.
