URS4 Steering issue (video)

[hugokx]

Hi all,

After replacing the bomb on my URS4, I now have an issue with the steering. There is a loud grinding noise when I turn the wheels at low speed or at rest. it sounds like this

You can hear it (with earphones) at 12seconds for a long time, this is a really loud low frequency vibration. It can be heard briefly throughout the video. Sometimes it lasts for a while sometimes just long enough to notice it. When it lasts long, I can make it disappear by revving the engine higher. I asked my friend to try to locate where it comes from and she pointed out to me that the steering rack seems to vibrate when it happens.

Could you help me?

I reckon my hydraulic fluid may not be the cleanest, so maybe it is just that.

Thanks mates!

i guess when you're flushing the system or draining the ps fluid.there's the air lock inside the system.you need to turn the wheel lock to lock for a couple times to be bled the air out.
