Frequently Asked Questions
How many steering parts fit the 2017 Audi A8?
Our catalog currently lists 48 steering parts for the 2017 Audi A8 across 5 subcategories and 17 brands, covering all 3 engine options (3.0L V6 Supercharged, 4.0L V8 Turbocharged and 6.3L W12). Each part is matched to the engine(s) it fits.
Do steering parts differ between 2017 Audi A8 engines?
Some do. 27 parts fit every engine; the other 21 are engine-specific. Each row (and the filter at the top) shows which. If you're unsure which engine you have, check the emissions label under the hood or the 8th character of your VIN.
What are the signs of steering problems on a 2017 Audi A8?
Common symptoms include play or looseness on center, a whine when turning, fluid weeping from rack boots, or uneven tire wear on the front axle. If you notice any of these, identify the affected subcategory above and cross-reference the part numbers listed.
What should I replace at the same time?
Where labor overlaps, replace the inner and outer tie-rod ends together on higher-mileage vehicles, then get an alignment.
What do the market flags (US, CA, MX) on each part mean?
They show the market for which the manufacturer published application data for that part — where the vehicle was first sold, not where the part was made. If your 2017 Audi A8 was originally sold in the US, the safest choice is a part marked for the US market.
How do I make sure a part fits my 2017 Audi A8?
First match the engine — each row shows which engine(s) the part fits. Then flush old power-steering fluid when replacing a pump or rack — grit in the old fluid is the number-one cause of repeat failure. The notes column carries position and trim qualifiers where they apply.
