OK, I have searched and searched...but not luck. '73 Blazer Crossover steering Dana60 I put a new 2 wheel drive gear box on, turned it back and forth 100+ times but sitll no real power assist. I took the gear box back because I thought it was no good. I did the same thing (back and forth back and forth), but still no workie. If I have the wheels in the air, I can easily turn from lock to lock, but as soon as the wheels are on the ground, the pump starts squeeling after 1/4 turn. I replaced the PS belt and still the same thing...I can drive my truck but have very limited power assist. Also, the wheel does not return to center or come back at all when I turn to the right or left... Here is my question: - Is it possible that a new gear box somehow fried my PS pump or that a new gear box exceeds the output of an old warn down pump? - What causes the steering wheel to go back to the center when you let go? - Any other thoughts?
