Brakes are wimpy steering wheel wont turn at all unless you give it gas f350 07?

Answer 1

I suggest getting a new Power Steering pump. If your truck has a hydroboost set up, which it probably does being its a F350, The power steering pump supplies fluid to the steering box and the brakes for more braking power.

To find this out, look at your power steering pump. There should be 3 hoses coming out of it. One Supply line, and 2 Return lines. The supply line should go to the steering box, then to the hydroboost which is on the firewall, driver side. It's not huge like the vacuum boosters. Then there should be one return line coming from the booster to the pump and one from the steering box going back to the pump.

I hope this helps you out.
