Steering not enough vacum on idle?

[alialhozami]

hey guys i got a GQ td42 swb and since i got it ive been noticing when turning on idle and also makes a vibrating growling sound, but on higher rpms or even just revving a little it works well, ive already tried adding sterring fluid, it got better but still exists, any suggestions?

G'day and welcome to the forum mate. My GU does that sometimes, normally on a cold morning. Sounds like brake rubbing? Never got any better or worse and been there for a couple of years now.
You might like to go over to introductions and post a bit about yourself too mate.

Sounds like possibly a worn steering pump which would mean it has a slightly lower flow at idle.
Even if the pump is OK some vehicles with engine driven pumps will do it if you go to full lock at idle.

Try a flushing, replacing and bleeding the steering to ensure there is sufficient fluid and no air.
If it still does it and it is bad enough to warrant fixing the issue I would look at a replacement pump.

I doubt it is mechanical IE something binding or bent but that is an outside chance as well I guess

Could it have something to do with the vacuum pump on the alternator if thereone fitted?

If he topped the Vac Pump up with Power Steering Fluid then, yes, that will cause issues.
(Sorry Clunk, couldn't resist, I am on fire today and it isn't even midday yet)

The OP doesn't quite make sense to me so I went with vacuum being power steering fluid pressure

Well thats why I asked, because I dont know what the vacuum pump does. Thought it may have worked in conjuction with clutch and/or steering
