Power Steering Screeching

Hi guys,

 

My power steering pump is screeching quite badly on cold starts but seems to happen more likely on warm days.

 

So when I start the car, it immediately makes a very loud screeching noise and goes away once I get the car moving a bit/give it a bit of gas. I thought it could be the pulley but recently it started to stop working as well after the cold start for about a second when turning the wheel.

 

Will try and get a video, but I just tried to get some videos this morning but it decided to start up without making a noise or anything.

 

Anyone had the same problem before? The real question I need answered is whether I need to replace the pump completely, or can it be rebuilt/repaired whatever.

 

Car is 2007 Legacy BP5 turbo JDM.

 

Thanks in advanced people!

Could just be the belt slipping, try tensioning the pulley if you haven't already, check the belt isn't fraying around the edges etc etc. 

 

P/S pumps can be rebuilt but obviously depends whats wrong with them. Can get quite expensive quite quickly though from my experience.

Note: belts made from EPDM will not visibly look old until they're well due for replacement. Is the belt actually new, or does it just look like it's in decent condition?

 

Check the depth of the grooves, if the ridges on the pulley are close to bottoming out in the grooves the belt is stuffed. 

 

EDIT: just adding more tension to an old belt isn't a long term solution - belts are cheaper and easier to replace than alternator and power steering pump bearings

      Afternoon team,
      im new to the group first time posting. Im hoping some body can help me get my launch control all dialled in on my link g4x. Ive had the computer and car all tuned from chris at prestige awesome knowlegable guy super happy with the results but now im wanting to get my launch/anti lag all dialled in. Ive been reading multiple different forums etc all with different conflicking information which has made me nervious with what do i listen to this or that if you get what i mean. Now ive started to make myself familiar with my PClink software etc the past few weeks and im eager to learn how to do minor setups or tweaks etc so im not relieing on my tuner so much and obviously saving myself abit hurt in the back pocket. 
      Now back to the question at hand.... Im wondering if theres and one who could please share there knowledge and wisdom with setting all my values, timing, fuel etc when i have launch control armed and engaged, or even a launch tune file they can possibly send me to load onto my tune. Ive figured out the setup of my digital inputs turning launch control on etc and its obvisously on its pre set factory settings. It engages but doesnt sound the greatest or as angry as it should i feel. Hence reaching out to you good buggers. 
       
      Cheers in advance for any info and help yous maybe able to give me.
       
      Cheers Shaun
