Hummm, I never talked to AJ about it. I did it because of the ram assist and needed somewhere for the extra fluid to go because of the imbalance of the ram assist setup. So I came up with this fairly simple fix for that problem. I don't think either you or I are the first to do it but you have to admit that it is a pretty simple idea. If you jack your steering much, it will tend to get hot. So if you're in the process anyway, why not just add some more volume it certainly will not hurt anything.
BTW I added a cooler too. Cooler fluid will make the seals etc. last a lot longer. The IFS box and Tacoma pump were not designed to turn 35" tires in the rocks so every little bit would tend to help.
And oh yes, it's not hard to get a good bleed. Just fill it, start crank stop to stop a couple of times while watching the level, then shut it down and wait a couple of hours. Top up as necessary and you're all set to go. Most folks tend to keep it running and keep on cranking the steering wheel. That just aggravates the foaming. If folks just shut it down and let it settle for a couple of hours, it's a lot easier.
