Last couple of days its been 15-20 degrees outside when I went out in the morning to start my truck, not plugged in. It starts fine, but then you hear this noise, the best way to describe it is like a loud moaning, I`m pretty sure its something in the steering cause when I move to steering wheel it gets louder. Its loud enough where my dog looks at the floor and kinda tilts his head looking for the noise . I drive about 10 miles to work and it does it all the way to work, and on Sunday the wife and I tooled around for a couple of hours and it was still kinda doing it when we got home(not as loud) It did this last winter and it went away as soon as it got warmer out, now I wonder if I`m hurting something, any ideas on what to look for?
thanks

 

My 01 used to do the same exact thing. It was actually somewhat stiff until it got warm.

Dunno. Might be the viscosity of the fluid in the colder temps.

 

Mine is/was doing to same thing when it was 5* here, was told by infidel to add a bottle of Lube Gard Power Steering additive http://www.lubegard.com/automotive/p...rotectant.html

Haven't tried /found it yet now that its warmed up around here

 

Bad link.

This should work

 

I also had the same thing with my '01, the Lube Gard worked! Quiet down to 5°F last winter. (Any colder than that and I don't go out!)

 

I put Royal Purple in mine.

 

Mine does it every year when its cold.Never tried addative,maybe I should as my steering sucks

 

Try checking the fluid level?

 

I agree. Check the fluid level. when mine was doing the fluid was low. Filled it up and no more moan.

 

Had the same problem with my '02. Switched to a synthetic power steering fluid, problem solved, even at below zero temps. The pump is moaning because the steering fluid is so thick at cold temps.

 

as an additive or did you replace all

 

I replaced it with Royal Purple Max EZ
