Power steering issue
Vette Obsessed:
Thanks for all the good info/advice Chromie. ;42
For what it's worth, I had a fellow at Winton this weekend ask me about my PS noise as he had the same problem too!

2/ Faulty power steering lines/fittings/hoses (meaning dags/sharp objects inside the line causing airation or sharp bends/calapsed hoses causing restrictiuon)

In my case Chromie, I am putting my money on option two. The rack is likely coming out in the next month and all systems are going to be checked. A new pump is also going to be purchased - just not sure if I am going OEM or reinventing the wheel yet...
Chromie:
My choice would be "new"
I have fitted some remanufactured ones and some didn't even work thus you test/bleed them in a bath of oil.
But mostly I have been successful with them
Racks do not cause problems so unless it is clunky/leaking oil or very old it is a waste
Hses on the other hand yep do them make sure that you make them yourself as most hose places stuff em up.;30

It was the rack supplied by the convertor of my car - hence why I don't have a problem going over it to make sure it is as it should be.
As for the pump, I will definitely buy new if they are available.
I'm glad you mentioned hose places stuffing them up - I thought it was just me having bad experiences. I've never had a line done right first time round. :b4

No offence chromie but I reckon the power steering system in a C4 is far superior and simpler than earlier models. Your knowledge is very good and I appreciate it. But, idler arms, pitman arms, & draglinks etc in days of old were very good and still are, but pretty complex stuff when compared to a steering rack system. Just look at the conversion on some C3s (and I hate saying this) the drag link is often fit at an angle that is wrong. It is pretty hard to muck up the conversion when a rack is used.
I do wonder if the rack on some C4s when converted to RHD is different to others. The rack installed in mine is from a buick and that is meant to be a secret!!;43
It all operates fine but has that dang nuisance noise that appears when a C4 is coming on song. Still ok, the corners keep coming, I installed louder rear mufflers and this has helped, but now I'm looking at 800watt subs!
VO sounds like ur on the job, please keep us posted!:drink

Some updates on my PS issues in the '01...
I drained and flushed the old fluid and replaced it with Royal Purple MAX Ez. I modified an old reservoir cap and with a MityVac made it into a PS vacuum bleeder. Did all the turning left/right with the wheels off the ground, engine running and then pulled a vacuum on the system as spec'd in the manual. The fluid level dropped about 200ml so in my case there was a substantial amount of air that couldn't be removed through the steering wheel.
PS pump was silent though and removed a slight high pitched whine that I had never been able to locate. BUT the car had steering shudder at moderate speeds up in both directions even though the groan when hot seemed to be gone.
SO, I pulled all the RP fluid out of the reservoir (didn't drain the whole system) then topped back up with Valvoline Synpower. Whine is back along with the hot groan but the shudder is gone.
I seem to be out of self help options and guess I need to start thinking about replacing the PS pump.
Chromie, what do you reckon?
