power steering

[yoss]

Hi

The power steering on my 04 monaro cv8 seems to have stopped working.

it had a new quick rack from pedders fitted a year or so ago, so i presume the problem is not the rack itself.

the belt was replaced approx 50,000 mls ago. So does it look like the pump is at fault?

if so is there an easy way to test it?

Cheers Yoss.

Investigated a bit more tonight, have removed the belt and found the pump pulley to spin very freely by hand. I have had the resevoir off and no blockages

Im pretty sure there should be at least some resistance even by hand?? do they have an in-built Pressure relief valve? possibly stuck open?

Or is the pump Kapput?!

Cheers Yoss

Update

Decided to fit a new pump, ( 04 cast iron one from Rockauto) two bolts three pipes and £150 done.. Flushed n' bled out the old fluid as per instructions

that came with the pump.....No change!!!.. With the car up on stands I can grab the road wheels and go lock to lock..I have spoken to Roger at Pedders,

he and others think its Unlikely to be the rack itself. Spoke to the garage

that fitted it, they said everything Iv'e done is the same as they would do.. the question is what to do next?


Cheers Steve.

Hi

Yes thats about how it is. though steering to the left has a bit of assistance.

Well its been in my ownership for 50,000 miles now showing 120,000 had the rack replaced at 105,500 (the old one leaked) always had ATF which is

correct as spect on the filler cap. ( if I was a bit younger and fitter I'd put the old one back on) and yes you can hear the engine note change when it

reaches full lock. wheels up..

Hi

Finally got the problem pinned down. As sugested by Roger at Pedders, and not much else left to change.

It being fathers day, my son came up and we reffited the old leaky rack... Power steering was restored.!!!!

Cheers, Now not quite so fedup.. Steve..
