I drive a '98 2.8QM, and for about the past 3 days or so, something in the steering is grinding when i turn the wheel to the right, while driving, and sitting still. I can feel it in the wheel as it grinds and it's increasingly harder to steer while sitting still, both ways.

any ideas? i was thinking maybe CV, rack, or PS pump?
any input would be very helpful

 

Did you check the power steering fluid?

 

where is the reservoir? i can find the clutch, brake, and washer, but i can't seem to find the powersteering one. help please

 

Green cap behind the driver's headlight. Only use Audi fluid - it's mineral oil based, not standard stuff at the parts store. I use Pentosin CHF11-S.

 

i thought that was for the clutch? well then that is full. i have filled it up with the same hydraulic mineral oil. any other ideas?

 

Nope, clutch and brake share the same reservoir. Could be a suspension issue, a bad rack, or something rubbing in the wheelwell.

 

well it appears now that only when it sits for a few hours +, it will make the grinding. but after driving it for a while it disappears. confusing confusing.

 

I've got the same issue in my 96 A4. Feel the vibration in the steering wheel. Haven't checked the fluid yet. Could it be a worn/wearing out belt?
