2006 Subaru Tribeca Wheel Hubs: What They Do and When to Replace

Wheel hubs are absolutely used on the 2006 Subaru Tribeca. Technical sources including the Subaru Service Manual (B9 Tribeca, Chassis: Wheel & Axle section) and the Subaru Global Parts Catalogue (FAST) specify unitised hub-and-bearing assemblies front and rear, with integrated wheel studs and ABS encoder rings. Typical listings include front hub unit bearings (e.g., 28373XA00A range) and rear hub unit bearings (e.g., 28473XA00A range). Major aftermarket catalogues from Timken and SKF also list complete bolt-in hub assemblies for the 2006 Tribeca, confirming fitment.

On the Tribeca, the wheel hub’s job is to keep the wheel securely located on the knuckle, carry the vehicle’s weight through a sealed bearing, and provide the mounting studs for the wheel. Because it’s a unit-bearing design, it also houses the magnetic encoder for the ABS/vehicle dynamics system. That sealed construction is great for longevity and keeps out dust and water—handy for Aussie and Kiwi roads—but it also means there’s no greasing or adjustment
