I don't even know where to start, I have a 99 Ford F250 Super Duty with a 4 inch lift. I believe the tire size is 315 80 seventeen's and they have a two inch spacer behind the rims. Ever since I purchase the truck had difficulty turning the steering wheel when the hours at a dead stop it's very hard to park in a parking lot.

I've replaced the gear box, I've replaced the power steering pump with a high-flow power steering pump and an overdrive pulley comma I have replaced the master cylinder and the hydroboost. I figured by upgrading the power steering pump would fix the problem however it did not so I took the next step and the next out and finally I found someone on the internet who said that they had a fixed and I purchased there upgraded steel braided lines that would allow more flow I installed that today and now I am still at Ground Zero it is doing the exact same thing however now whenever I brake hard I lose steering and it is very difficult to turn the wheel I've spent almost $1,800 trying to get the steering fixed so that way I can parallel-park if I was ever in that situation or just make it much easier to turn the wheel if I'm ever in a tight space. I'm pretty much out of options I've replaced every single thing that has to do with the steering can someone give me an opinion, or suggestion what my next route should be?

thanks in advance

 

One of your problems is the 2 inch spacers behind the wheel, they increase the scrub radius of the front end which throws the alignment off and makes it harder to steer, combining this with oversize tires and a power steering system that is marginal in actual power at best. You said you upgraded your PS pump, what did you use? You may need to get it into a good shop that can actually measure the pressure and volume of the PS system.

 

I got it from dieselsite.com and the overdrive pully. I took the tires off and that did absolutely nothing and then I also remembered that I just purchased a rough country dual stabilizer kit and I had that put on after I talk to one of the guys a diesel site he said and most of the trucks that have two and four stabilizer upfront those people drill the cylinders out because they're basically just for looks that a power steering pump would not be able to turn for steering dampers so I'm going to pull one of mine off and see if that helps any at all cuz I do recall driving around with not having them and the wheel turned pretty easy with a stock set up
