OK. Get this. There were two other factors I was unaware of.
The first was a possible hiccup in the revolution sensor. Had no idea they even made them. A mechanic told me that on a Chevy a customer had complained that the steering was perfect at any other time except when he went into one specific curve on his way home. Then it seemed there was a loss of power steering. Never happened any other time. So they test drove the truck. Sure enough the ONLY time it happened was on the curve that he specified. Boom! Revolution sensor.
Another mechanic told me that when I get home to my truck to over inflate the front tires to 60 psi. If the inflation corrected the steering then I simply needed new tires. I assured him that I still had another 4-6 months on them judging by my estimation of the wear line.
Which of the two would you guess was the solution to my trouble?
