Massive caster variance Side to side

I also watched birdsong
I checked both sides ten times and made changes as i went with repeatable results
I persinally dont think in this instance the brakes matter but for ***** and giggs ill re do it with brakes locked.
In the mean time ill focus my attention on the lower arm maybe being bent or the bush being clobbered or pulled away. Also ill re
Check the offset bush orientation but i know its correct. Ill also check strut rod length side to side.(and i have a new spindle which is going in). Because drivers side numbers were perfecto i dont think its the K.. also the car drives nice and straight and i dont see any pronounced tilt to the wheel that looks out of Ordinary.. main issue here is just wander at speeds=caster. Thanks for all the input to help me collect my thoughts in this. If all else fails at least i know i have bergaman uca to save the day. But id like to get it right and not use them as a bandaid.. but i will if i have to.
