Power steering issue

<< < (2/8) > >>

Chromie:
If you have any power steering noise while engine s running and steering is not being used and the oil level is correct then the chances are that your pump is faulty
(exception is if you have just flushed the power steering oil out);27
Also some power steering pumps will be noisy if the oil is old, contaminated or incorrect type of oil used

Cameron 77C3:
So what your telling me it's a cow of a job and it takes time to get all the air out????

Chromie:
No cam:b4
What I am saying is that it is a reasonably simple job based upon
1/ Equipment
2/ Experience
3/ Knowledge of the item you are servicing
4/ Some common sense
;42
And sometimes it can be messy when flushing out the power steering oil.:spook

Cameron 77C3:
Thanks Chromie.

We did all that, except the part of having the wheels off the ground.  I'll pass it on and see what happens.  It has to be a process thing as both pumps do it.

I have heard of additives that you can put in pumps to quieten them down.  Any comments on these?

Chromie:
Yes cam it could be a processing issue, but if both pumps do it then it maybe a mechanic issue especially if the first pump did not make any noises until after the oil flush.
The reason why the wheels are off the ground is to reduce strain on pump and steering linkages when going from lock to lock.
Also the true way to bleed power steering systems is to crank the engine over by starter motor until most of the air is out, but this puts too much strain on the starter motor especially old one's
So if you want to do it correctly, remove the spark plugs so the starter motor strain is reduced don't forget to remove the power wire from the distributor.
Sometimes power steering pumps will make a noise for a week after servicing/flushing/repairs depending upon mileage.
Hope this helps;-)
