Just replaced my right front assembly with a replacement from detroit axle.
The only problem I ran into was a frozen lower caliper bracket bolt. After being unable to free the bolt, I ordered a bracket, bolt and axle nut from a dealership.
For bracket: 26225AG060
The hub assembly came out easier than I thought it would. I used the flip the rotor on backward and beat with hammer method. I whizzed the axle nut off with my harbor freight impact wrench.
Here's hoping the Detroit Axle part lasts as long as oem or other aftermarket. Can't say I'm too optimistic after seeing made in China. Amazon 65 for pair of fronts though.
I found these posts helpful for torque specs.
