[V8] Lumpy Power steering

Four things come to mind to me:

slipping belt (will be evident soon...)
air in system (usually easy to get out)
wrong/too heavy oil
pump is worn out

I am using the Chevron Rykon 32 oil (for maybe two years now) and it seems to
work great - but in extreme cold it may be a little thick. It is fine after just
a few minutes of driving though.
There is a RYKON 16 for the more northern folks.
The really nice thing about this oil is it is fairly cheap, and you have to buy
it by the 5 gallon bucket. You have plenty of oil to flush the system out
several times and still have plenty left over.
I also highly recommend an in-line filter. My hydraulic oil stays pretty clean
after several flushings and with the filter.
RYKON is clear out of the bucket.

Here are some low res pictures of the filter:

> There's no problem at higher speed but try slowing down for a sharp
