like he said

im pretty sure dmax store carries them, and its pretty simple, i think there is 1 big bolt up front, 4 in behind and the 2 on your brakes and the abs hook up.. i could be wrong, its been a while

its easy though.. you might want a torque wrench.. or make em real tight

I would use 6 point wrenches and sockets and not be afraid to use cheaters. 12 point wrenches tend to slip off and screw up the bolts. I ended cutting things off with a torch during my last hub change on the old '04.

NAPA # is BR930416, or PBR930416, (P prefix is value line), the PBR hub assemblies seem to be fine, and shouldn't cost more than 160$.
