pretty sure the complete abs speed sensor and reluctor wheel are all part of the new hub bearing assembly.

the rim scratch:

looks like the rim was hitting the rotor; probably was installed on a vehicle with a bigger brake package or different rim offset.

 

No that's rim from bearing going and wheel wobble. But yeah ABS is built in hub

 

ok, truck is running good so far, i replaced the wheel hub assembly and the cv axcel shaft.

i went ahead and ordered another wheel hub assembly for the drivers side, i figure it won't take long for it to fail. my question is, should i replace the axcel too?

so my question is, should i have to get it aligned? Its not pulling or anything...

 

Yeah good call on other wheel hub but no u shouldn't need to replace anything if its not broke just look it over
Yea best to do a alignment

 

technically you shouldn't need an alignment after just replacing the hub but I'm assuming it hasn't been done for a very long time since your hub got that bad so it definately wouldn't hurt
