to check the hub, jack the car up and leave the tire on, if it wiggles at all then you got a hub going...
i just did mine, it was from ZZP and so far seems to be holding well, got about 1000miles on it so far... pretty easy job, just remove the wheel, brake caliper, and three bolts coming in from the rear of the hub, then the axle nut
(36mm) and the wire plug.... i used a gear puller to push the axle out...
the torque specs are 100 on the 3 wheel bearing bolts, and 180 on the axle nut... i don't have a torque wrenc so i just guesstimated.
