I decided to replace both upper cups due to the bolt that was welded at an offset inside the original cup. The air hose was actually 1/2″ hydraulic fluid lines that was rigid and difficult to move around. I’m guessing the installer back then decided to use the shock mount hole since it was very large in diameter.

The lower cup on the original setup had a “floating” configuration. That’s when the cup is seated on the lower control arm not bolted down or secured. I would have done the same again since the original setup had probably lasted over 20 years. After speaking with my Cuz’ I decided to take his advice and secure it down with a bolt that was welded in place.

There is a “horseshoe” hole on the lower control that can be used to allow a bolt go thru. The lower cup is then secured down using a strap. In this case I was out of steel material and used scrap aluminum I had laying around the shop. I will replace the temporary strap with a 1/4″ steel plate at a later date.

Using a transmission jack to hold the lower control arm and disc brake setup is the best thing ever! It is so much easier to maneuver around then screwing around floor jack that always seems to get in the way. This is really helpful when pressing in the upper control arm ball joint back into the upper spindle.
