Just replaced the power steerring box in my 66 Satelite.
Was primarily for a leak. but also partly due to how it drove . It seemed to dart around a bit on crappy roads

Just drove it and noticed drives a little better but has a noticable difference in the assist in required effort from left to right . I dont remember if it had this before or not

Turns left super easy,,,, but requires a good bit more effort to turn to the right . Not manual steering effort but definitely more than the opposite direction

Jacked it up think I had a valve off center .
But started it up and steering wheel stays rock solid in the center while up, I turned the steering wheel and I can notice an effort difference even while jacked up in the air with both front wheels hanging
