I just purchased a 2002 f350 srw, 7.3 diesel and having some problems with the powersteering. When I test drove it, noticed that the powersteering was VERY easy to turn almost as if the truck had a load on the rear raising the front up so very little tire made contact with the road. Or the alignment of the truck had a REALLY high camber reading. I thought no big deal, I can fix it when I get around to it. But right after I bought it, I took it out of town and the powersteering pump blew the front seal out plus noticed that the fluid was so hot that it melted the powersteering cap dipstick, I replaced the pump. I got 1 mile then the pressure of the pump blew the resorvoir back enough to leak off the fluid out( i thought maybe a bad rebuilt pump). I replaced it again and this one lasted a week and replaced it again(blew front seal again). After 2 weeks I'm about to replace it again, it's loosing fluid(not sure where yet). Is it possible that a valve could be bad in the Hydroboost or that could be boosting the p/s pressure to cause these symtoms(over sensitive steering, heating up the fluid enough to melt the dipstick, pressure high enough to blow the front seal or resovoir out? Have any ideas? Thanks
