To clarify some. If he is going to check the rotors, the axle tube needs to be set to 0 degrees. In this case, it doesn't matter since that axle is beyond repair given how cheap a replacement should be. Also as pointed out, the trackbar frame side mount is bent or someone will have to prove it isn't somehow.
The lower part of the left side inner C is bent. All that will do moving forward is take out the upper in a hurry. The lower can handle some angular misalignment, the upper can not.
He needs new front control arms, straight frame side trackbar mount if using the stock trackbar or get an adjustable front trackbar, new front axle, and new steering links complete. Damage to steering gear TBT but I'd certainly spend some time making sure it and the steering shafts are not tweaked.
How do you know it has an aluminum block? Best I can tell seeing the O2 sensor tab, it says 4.0 to me but I can't fully verify from the pics.
