Dorman - OE Solutions Lateral Arm P/N:528-174
Dorman 528-178 rear right lower lateral arm for the 2008-2014 Subaru Tribeca and other vehicles holds the rear wheel in position from side to side.
A worn rear lateral arm can show up as a clunk over bumps, uneven rear tire wear or a rear wheel that will not hold its alignment. These signs alone do not prove this arm is the problem, since a worn rear shock can cause them too. This listing is one arm for the rear right, with one on each side of the rear axle, so the rear left is ordered separately and both sides are normally replaced together.
This is a direct-fit replacement for the 2008-2014 Subaru Tribeca and the 2006-2007 Subaru B9 Tribeca.
