osmonxp Posted August 21, 2017 Share Posted August 21, 2017 Hello, I have yet another question. This issue stared today and don't know how to tackle it. I have a 2012 Subaru Legacy 2.5l Premium that I purchased used. Every time I move the steering wheel either left or right it make a horrible noise and I'm afraid it may be something serious. I replaced the fluid and bled the system turning the steering wheel end-to-end and also used a vacuum pump to remove any remaining air but that did not help. Any advice you can provide will be greatly appreciated. Please watch the video to have a better idea of what I'm talking about. Link to comment Share on other sites More sharing options...
john in KY Posted August 21, 2017 Share Posted August 21, 2017 (edited) Probably just need to tighten the belt. If the problem is a slipping belt, replace it. Edited August 21, 2017 by john in KY Link to comment Share on other sites More sharing options...
osmonxp Posted August 22, 2017 Author Share Posted August 22, 2017 Probably just need to tighten the belt. If the problem is a slipping belt, replace it. How do you know if the belt is slipping? I replaced the tensioner and idler pulley with aftermarket parts and don't know if that has anything to do with the noise but the slipping belt did cross my mind I just don't know how to determine if that's the issue. Thank you. Link to comment Share on other sites More sharing options...

monkeyposeur Posted August 22, 2017 Share Posted August 22, 2017 (edited) I didn't see a link to a video in your post so I don't know what your sound is like. If its a squealing sound then it's the belt. If it's a lower pitched grinding noise then it is probably air getting into the system from a bad o ring connection in one of the lines, a bad seal between the reservoir and the pump, or a leak from one of the rubber hoses that joins the sections of hard lines. The lower pressure line has a clamp fitting which can go bad but be fixed with a good hose clamp. Are you getting any leaks anywhere? Are the boots of the steering rack torn? Power steering pumps can go bad but that is pretty rare. I just dissassembled one and there isn't too much that can go wrong on them mechanically unless they are run on a low amount of fluid. Have you tried going lock to lock with the power steering reservoir cap of to further bleed air out of the system? I wouldn't get too worried. Even if it is a blown steering rack it's not too bad of a job to replace it. Edited August 22, 2017 by monkeyposeur 1 Link to comment Share on other sites More sharing options...
