Front Right Upper Spring Seat (Suspension)
? This small but critical suspension piece sits at the top of the front right coil spring and helps the spring load the strut correctly. It is needed to keep the spring centered, reduce metal-to-metal contact, and protect the strut mount area from shock and vibration.
How it works
When the wheel hits bumps, the coil spring compresses and expands. This seat acts like a locator and cushion, holding the spring end in the right position so force transfers smoothly into the strut assembly. It also helps control noise and keeps the spring from โwalkingโ under steering and braking loads.
Signs itโs worn or broken
- Clunking or creaking from the front right corner ?
- Uneven spring position or visible rubbing marks
- Harsh ride, vibration, or steering feel changes
What happens if you ignore it
A damaged seat can let the spring shift, causing noise, faster strut mount wear, and possible spring/strut misalignment. Over time, this may lead to poor handling and premature suspension failure.
