power steering noisy...

I have 06 f350 diesel that I just picked up used. The truck runs great but the power steering seems weak and noisy. Kinda has a shutter in the steering wheel when it is turned. The fluid is pretty dirty and probably needs to be changed.... and or the pump. Any recommendations?

Let me know what you guys think

Thanks
Daniel

If you have hydroboost, there is info re bad fluid and brakes jamming... see tech folder.

pull the return line off at the brake booster, run it into a 5 gal bucket, start the truck and add new fluid to the reservoir until you have changed out the system volume. pretty simple really. 3-5 quarts can't remember exactly how much i used

How do I know if they are hydroboost? The power steering pump and the brake system look totally separate. There is a master cylinder just like a normal truck. The Power steering was up front on the driver side.

Anyways I pumped the old fluid out today and replaced it with MercV. Made a world of difference. The old oil was very thin and wore out. Smelled burnt. I replaced t he fluid and it is much better. I will probably do it again after a few days and see if that fixes it.

Thanks

if its a diesel it uses hydraboost. hboost uses hyd press from P/S sytem to power the brakes. you should see a pair of hydraulic lines going into the brake booster
