Product Details

The KYB Excel-G brand line is focused on OE replacement performance for drivers who want the vehicle to feel like it did from the factory. This strut uses OE-quality components and is assembled on KYB production lines used for original equipment manufacturing. It is engineered for the front right suspension position on 1999-2002 Mercury Villager and 1999-2002 Nissan Quest applications, making it a practical choice for restoring ride control on these minivan platforms. This part cross-references Monroe Shocks & Struts 71569 for the same application.

Common Problems This Strut Can Address

• Excessive bouncing or poor rebound control
• Loose steering feel or delayed lane-change response
• Nose dive, body roll, or unstable braking behavior
• Uneven tire contact caused by worn damping performance
• Noise or vibration from a worn front right suspension strut

Installation Notes and Tips

Fits 1999-2002 Mercury Villager, front right. Fits 1999-2002 Nissan Quest, front right. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. KYB recommends new strut mounts, part number SM5326, to reduce noise and vibration, and a KYB strut boot, part number SB101, to help protect the strut from dirt, debris, and salt.
