What should I replace at the same time?
Where labor overlaps, replace the differential or transfer-case fluid with any axle or seal job while everything is already open.
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 2018 Audi Q3 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 2018 Audi Q3?
