Does it appear without using the brakes, for instance when just
accelerating? I have had this on my own 9^5 and felt it on several 9^5s
that was provided by my dealer when my own car was on repair. It seems
to appear at cars from 50000 km and upwards. The solution seems to be to
fill more grease in the steering gear box.

Thanks to both for your replies. The vehicle has recently had new front
pads and I do remember having pads moving in the caliper on an early
900 causing a knock but this could not be felt through the steering
wheel and this car brakes fine with no shudder so presume discs are ok.
Thinking aboutit I can feel the knock at other times but it is hardly
noticeable at speed. Can I ask if yours was cured completely with the
grease addition? I thought the steering racks were sealed for life but
I am not certain.
Thanks again
Cheers

Some funny thing here today:
My car (non-saab) had a slight "shake" in the steering wheel at speeds
between 100 and 120 km/h. It was on my list to be "examined".

Today I pumped the tires, and noticed they needed quite some air.
Now... tadaa! Most of the shake is gone. You can only feel it when you
really pay attention.

Not saying that this is the cause of your problem. Just saying its
worth to check the basic things first.
I never imagined it would make such a difference.

Richard, yes, checked all round but this is more like a random knock
unassociated with any wheel speed or rotational sequence.
Thanks all the same

On the cars I've driven the knock was only noticeable when accelerating
from almost zero speed, more noticeable when turning at the same time.
On my car the knock disappeared after the grease injection. How this is
done I don't know, it was done by the dealer.

What you are describing is a knock from the steering intermediate
shaft, the unit is removed and greased, or replaced. The shaft is the
link between the steering gear(rack) and column. You may also get
light knocking at times when just turning the wheel slightly right/
left. You also want to make sure your service personnel has check
your suspension and subframe bolts for adequate torque, it is part of
the service that you paid for. If your feeling it in the wheel though,
I would lean toward the intermediate shaft. The rack and pinion is
only serviced by replacement.

Think that's pretty close although I may lean to subframe bolts etc as
I notice I can worsen the problem by going on and off the throttle or
brakes. Wouldn't have thought the short shaft would have been altered
by this. Having a look at weekend and will post my fidings if any.

Ended up consulting main dealer who confirmed he had lots of 9-5's with
this problem which is the short shaft problem. He said the grease
repack job would only be a short term solution and as mine was only
very slight it would be wiser to live with it.
Thanks all for your input. Really appreciated.
