I was on another forum about mustangs but this also is related to our trucks of course. They are trying to tell me that flushing the power steering is useless. Being a newbie on that forum I did not want to stir up a lot of you know what. Any opinions for or against?

 

I found this thread to be interesting and agreed with all that was said.

Power Steering Fluid - Lifeline of your steering system - HondaClub.com - Online forum for Honda and Acura owners

 

I think considering any fluid "lifetime" or "non-serviceable" is a bad idea.

 

Your PS fluid has additives (for your seals, etc.) that wear out and suspended smooge that can't be helping, why wouldn't you? What I do on a more regular basis is just siphon what I can out of the reservoir and replace that, not as complete but I do it pretty often.

 

All fluiid ages and with what we put our trucks through I'd rather change it and continue to have power steering than not and have a hard time dealing with how heavy these trucks are.

 

That is pretty much what i did of my mustang. I just drained one of the lower power steering hoses 5-6 times after driving it a couple of miles between drains. The fluid looks new now and only went through 2 quarts and less than $20 for mobile syn. atf. Same as I used on my truck.

 

My power steering became very noisy, and got noisier with time. I changed the power steering fluid and silence the pump. That was in a 99 F350.

My car was noisy as well. Much quieter now. I agree with all you guys. Don't know what is up those guys on the other forum. I've never heard it is useless on this forum.

 

To change it, take off the cap and put a funnel in it. Disconnect the return line from the brake booster and connect a 3/8" vinal clear hose to the fitting now exposed and start the engine. Put a can of fluid in the funnel and turn the wheel and pump the brakes untill the discharging fluid is clearly new fluid. Stop, replace return line, reinstall cap, and drive around untill any air is eliminated.

Do not run out of fluid that is being added through the funnel.Its easier withn a helper to pump the brakes and turn the wheel while you keep the new fluid flowing into the funnel.

Yeah, that is how I did it on my truck, thanks. I just did not know how to flush it on my car and posted asking for a flush procedure. Didn't get much help. Just people posting an article about shops pushing not need fluid changes and it being a waste of time.

 

Thanks for the reminder Grant. I should do a flush and fill on my daily driver.

 

If your truck or car has 100,000 miles on it flush it. But it's not my vehicle.

 

It good to change it.. and also use Mobil 1 syn mercron ..ATF.

 

So what is a good diy procedure for flushing? I know how to on our trucks. I just did repeated drains on my car until the fluid was nice and clean.

 

That's what I used on the car and truck... Good stuff.
