Is the left and right the same for the assembly with bearing? I've got to order one for the left driver's side and I just want to be sure.

 

only for the front wheel bearings

 

What about the years? Does 2006 match 2011 or does the fit change?

 

they all fit. The only differences are if your car is rear wheel drive or all wheel drive.

 

Wheel hub bearings assemblies generally come as complete units with the bearings already pressed in, but whether the left and right are the same depends on your vehicle’s design. On many cars and trucks the hub with bearing is identical for both sides and can be swapped, but some models have side-specific hubs due to ABS sensor placement, lug orientation, or mounting differences. To be safe, double-check your vehicle’s part number before ordering to ensure you get the correct hub and Deep Groove Ball bearing assembly for the driver’s side.
