What constitutes dirty?

[Murphy]

The stuff i put in is pink. 3 days later the level drops and it is black :(

[Baj]

Well, I am no expert, but that doesnt sound good. But what do I know :)

[rs_andy]

it's probably been in there since the car was made, it's bound to be dirty by now....

only way to know is to drain it and replace it a couple of times till its clean and then check it regularly. I'm assuming there is some way to drain it of course...

[Murphy]

Pop down to my house and have ago Andy :D ;)

Well I didn't have any in mine when we checked at Trax... And what was in there was pretty murky. But the steering still goes left and right.

[Murphy]

Maybe it is the pump that moans and growns, or is it the wheel bearing?!?!

[pzorb]

Well I only bothered to check the PAS fluid because the car started really groaning when turning. Topped up, and has shut up. Happy days.

[Murphy]

Good stuff, i will bung some more in later :D

Right - I have added some PAS fluid, and it still groans around right hand bends / roundabouts. Are we thinking it is a wheels bearing?

Its a sealed unit it shouldn't be black after a few days, drain the whole system and see what happens over the next few weeks, otherwise might be a new rack,

I have/well Arb's lol a secondhand one if it is the latter,

Are you sure the groaning is not this? http://volvospeed.com/Repair/70steering.php

nice :(

I will attempt to drain the fluid later.

Re groaning: IMO! When not moving with engine on, turn wheel to full lock and keep pressure on. If this is the noise, it is not likely to be the bearing.

But as you have topped up the pas (which stopped mine groaning) it sounds like the wheel bearing, esp as it gets worse going round bends.

To check if its the wheel bearing, raise that wheel off the ground, put your hands in the 12:30 position on the tyre and try and wiggle the wheel. If theres play in it then its most likely wheel bearing. Take the wheel off and see if theres loads of sludge/grease around the centre nut. If there is, then your bearing is cream crackered.

[Murphy]

Right. I will try both tests tomorrow :)

[Straker]

Black means carbon is in the fluid or it's burnt (getting too hot).

Neither is good, replace all the fluid and keep and eye on it. PAS systems can suffer generally with leaks, pump and seal failures.

[Murphy]

Erm - i think it might be the brakes you know? I will investigate more, but i just get the feeling one is binding on right hand bends?
