How many TC7870 joints do I need?
The listed applications use two per vehicle. Each is sold individually, so order two to replace both front upper joints as a matched pair.
What are signs this ball joint may need replacing?
Clunking or knocking over bumps, loose or wandering steering, and uneven front tire wear can be signs of a worn ball joint. Diagnose the cause before replacing.
Does the TC7870 include a boot?
