Icon upper control arms
 

Are these hard to install? Nothing needs to be pressed in the spindle? I'm debating on getting these vs other brands?

They are not too hard to install, you will have to press out the upper ball joint from the spindle and press in the adapter slug into the spindle.
you will have to move some stuff around the engine bay to get the upper arm bolts out.

Thanks. Are there any tricks other than a press to remove and install the slug?

I used a modified pitman arm puller to press out the ball joint and to press in the slug.

How did you modify the pitman arm puller to work?

ground it down some, bought it from autozone.

Thanks.
