Questions about this item

Will this 257030 rear shock absorber fit the original mounting points on my 2000-2006 Audi A4 sedan?

The Unity 257030 is designed as a direct replacement for OE shocks on 2000-2006 Audi A4 sedan models, excluding convertibles, and installs on the factory mounting points.

How can I verify the 257030 shock absorber is functioning correctly after installation?

After fitting, check for smooth damping through the full travel, no oil leaks on the body, and stable handling without excessive bounce or noise on uneven roads.

Does the 257030 package include mounting hardware or do I need to buy bolts and bushings separately?

The 257030 shock absorber is supplied as the strut unit only; original or new mounting bolts, bushings and top mounts must be sourced separately if the old ones are worn.
