What is the best way to maintain the stability of Audi A6's Quattro all-wheel drive system?

I recently purchased an Audi A6 with Quattro all-wheel drive and want to ensure that I am taking the necessary steps to maintain its stability. What are some recommended practices for keeping the Quattro system in top condition?

Regularly check and replace worn or damaged drive shafts and joints. This will ensure that power is evenly distributed to all wheels, maintaining the stability of the Quattro system.

Ensure that all four tires are properly inflated and have matching tread depths. This will help maintain the balance and traction of the Quattro system, especially in wet or slippery conditions.
