Power steering vibration

[Gelf VXR]

Ive driven several hundred miles since replacing my headers which involved dropping the steering rack, which I had disconnected the hydraulic lines, I refilled and everything was ok after I thought the air had bleed thru. Last week I noticed some vibration when pulling into the drive. I turned steering full lock a few times and nothing. Today it did it again, I felt vibration when braking, now when parked stationary and I apply the brakes and turn the steering wheel there is a lot of vibration from the front area of the car, the cooler I think.

Do I need to have the system bleed, I read here about a procedure that applies a vacuum to the system?

are the headers rubbing on the steering some how ?

I've checked all the clearances still there and bolts are all secured ok,

the reason i suggested that was on my forester the steering occasional rubs on the downpipe , it only occasionally happens when accelerating at certain angles as the engine mounts flex and it touches the exhaust , it's not obvious looking at it as when parked up no engine flexing and it's not close , it feels like a knocking on the steering column

The vibration can be felt in the steering wheel, and rattling from the cooler, I think it's air or maybe the pump failing when I turn the steering wheel, but I don't understand why applying the brakes causes it?

[vxr2010]

braking can slightly drop revs plus is there any flex when you brake in the bulkhead that you get with some cars ?

Bleed system again so as to eliminate that, then go from there, good luck.

A few threads on Ls2gto on this, I topped up fluid to the max level, left the cap off turned the steering wheel full lock a few times, it's better now, just a hint of vibration

I guess steering rack its got to come out now, leaking fluid everywhere, doesn't look like its any of the unions, must be from dropping the rack to get the headers out and back in again

Thanks for this, I'm thinking it would be the happiest s got stresssed while I dropped the rack

Where did you get your replacement, from oz or uk? Cheers

[L2VXR]

I got the low pressure one in the link from monkfish but they didn't have stock of the other high pressure one so got that from ebay oz

[Gelf VXR]

Would you have cthe correct part numbers?

[L2VXR]

The high pressure one I got from oz was made by kelpro part number HPS088 that fits the ls2 monaro. The low pressure return I don't know the part number but monkfish had it in stock so just got it from them. I think they also do a high pressure hose now that's modded to fit the ls2 both are fairly price considering there already in the uk.

Do you remember what torque you tightened to? I have received the part now and noticed it has a rubber o ring.

[L2VXR]

As I had no way of getting a torque wrench in anyway I just did them up tight with a spanner . It doe's say somewhere not to over tighten them but I did my best with a standard size spanner and I've had no leakes.

[Gelf VXR]

The torque setting is 0.3Nm which hardly anything at all, got both pipes now will get them swapped this weekend.

Here is the installation and air bleeding procedure in case anyone needs it.
