How hard is it to change the lower control arm bushing on a 1998 Buick Century? I printed out the detailed dealer directions from the public library and it says I need to remove the whole lower control arm. Is this really necessary or can I just lower the control arm enough to get the new bushing in place?
I just did this job on my 98 regal, and I own the service manuals also. The lower control arm bushing that usually goes, is the front one. The rear one doesn't usually go, it is horizontally mounted. The front one for some reason is vertical. The control arm must be removed, and put in a vise. The front bushings outer metal sleeve, must be driven out with a chisel. It comes out easily. The new bushing can be tapped in with a hammer. Hope this helps!

Jack up car and support on the frame just behind the wheel. Remove wheel. from bottom side remove the stabilizer link single bolt style is 13mm or saddle type 15mm remove lower ball joint pinch bolt 15mm with a pry bar then lower control arm can be removed from steering knuckle. then remove both lower control arm bushing bolts 18mm or 21mm ? out it comes.
Below are some pictures and instructions. I do not believe you need to remove the whole steering gear assembly but don't quote me on that. You may have a hard time with the ball joint but guessing you are replacing the whole control arm with a ball joint already installed. That's the easiest way incase you do damage that ball joint. Hope this helps with your project....

the bushing end seats properly on the arm bore. Then re-install the
upper control arm. When finished, take your Dodge vehicle to a good shop
