What It Helps Fix

- Clunking or knocking from worn rear upper arm bushings
- Uneven tire wear related to rear suspension wear
- Imprecise rear wheel alignment caused by worn control arm components
- Excess movement in the rear upper suspension mounting point
Installation Notes and Tips
Fits 2014-2018 Mazda 3, rear upper. Fits 2014 Mazda 3 Sport, rear upper. Confirm the rear upper position before installation and compare the removed arm to Delphi TC7864 for mounting-point and length verification. Because this is a non-adjustable control arm, final alignment should be checked after installation.
Quality Assurance
Delphi uses OE-focused testing and material analysis for its steering and suspension parts. TC7864 is exposed to extreme temperature cycling and salt-spray testing during validation to help support durability in real-world service.
