The Firm Feel Stage 3 steering box in my car has felt sloppy for awhile. I had suspected the coupler to have some slop but it always feels snug.
Still, the loose feeling on center or more specifically, from the 11:00 to 1:00 positions always annoyed me. I could turn the steering shaft by hand with the engine off and see a fair amount of movement before the pitman arm started to move. The splined shaft on the steering box moved in and out with the rotation of the steering shaft too. Today I adjusted the nut and screw on top. The 3/4" nut was cracked loose and the slotted screw was turned about 1/4 turn clockwise, then it would not move any more. I tightened down the 3/4" nut and drove the car. The slop is greatly reduced but a little still remains. I wonder if this means that I am at the end of what can be done with this box. I have considered a Borgeson box for the car so maybe I'll use this FF box in another car.
