The yoke or wherever it is that the front caliper
mounting bracket attaches is cracked and needs to be replaced.

I'm going to have someone do it, because I Can't
even get the rotor off.

Anyone have any idea how much this might
cost? Also, it'd help if you could tell me what
the part is called. The caliper mounting bracket
mounts to it as does maybe a tie rod.

Thanks!

 

The spindle (aka knuckle assembly). No idea on price. It is a good bit of work so it won't be cheap.
