most likely caused by this type of wear: Parts for steering box rebuild - https://forum.ih8mud.com/threads/parts-for-steering-box-rebuild.1254109/post-13890587@tway Worn components within the box that could not be adjusted out by preload. My guess is both the sector shaft and power piston teeth gears had worn down too much due to poor maintenance by PO's for the original 180k miles. I have since replaced the whole steering box with new from toyota (via amayama) and that has fixed the issue. It has made a huge difference in drivability on the road/highway. Same could be accomplished by ordering both new internal pieces along with a reseal of the box but when factoring in shipping, labor to have someone do that, a new box was actually cheaper than doing a rebuild of the original box.
