Installation Notes

Install on the front right lower suspension position only for the listed Audi fitments. Verify chassis number, model year, and drivetrain before ordering, especially on 1989-1991 Audi 80 and Audi 90 vehicles with the CH #8AL038656 cutoff. Because this is a bolt-in ball joint assembly, confirm the mounting style and suspension configuration match the original part before installation.
