Re: IML: power steering problem

["Robin Giesbrecht" <robings@xxxxxxxxxxx>]

I pulled another spool valve from a late seventies Mopar at the junkyard and 
pulled that apart taking note of some fits and clearances. The actual spool 
valve is a precision fit mated to it's housing.Then I pulled the one from my 
72 Imperial. Big difference is the fit of the arm(driven by steering box to 
move spool valve to port oil for assist) in the spool valve. The original 
fell out when I pulled the spool valve off the steering box.The one from the 
junkyard was a tight fit in it's spool valve. I had to pull hard to separate 
that one.These arms are balled at each end with a cut through the middle of 
the ball end which allows it to compress enough to fit into the spool valve 
cavity and then expand to create a tight fit. That is how I see it anyhow. 
Seems mine was worn out or defective. So swapped spool valves and arm after 
cleaning and resealing the spool valve. Works great. Car steers much much 
better. Auto centers and just drives nice. Wonder why I did not do this a 
long time ago. Always thought it was something else but after checking 
everything else there was nowhere else to go.
