Dorman - OE Solutions Lateral Arm P/N:528-289
Dorman 528-177 rear left lower lateral arm for the 2008-2014 Subaru Tribeca and other vehicles holds the rear left wheel in position within the suspension. It replaces an arm that is bent, cracked or worn at the bushings.
A worn arm or bushing can show up as a clunk from the rear over bumps, uneven rear tire wear or loose handling. Noise and tire wear have several possible sources, so find the cause first: with the engine off, look for a bent arm, torn bushing rubber or heavy rust where you can see them, and leave anything that needs a lift to a shop.
This lateral arm is a direct replacement for the 2008-2014 Subaru Tribeca and the 2006-2007 Subaru B9 Tribeca.

Build and materials
One lateral arm with its bushings. This listing is the rear left arm, and that side takes one; the rear right is a separate part ordered on its own, and the two sides are normally replaced together. Mounting hardware, a ball joint and a grease fitting are not included, so plan on new bolts, since the old ones may not be reusable.
