Can you unbend a bent knuckle?

[Exhaustgases]

That piece is cast. If you were able to reshape it, I wouldn't trust it's integrity afterwards.

Replace it

If any manufacture was to make that from a casting they should be immediately shut down.
That most definitely is a steel alloy forging, cast iron would not come close to holding up to the abuse that spindle takes.
Nor would it bend like that, it would shatter. Oh and even cast steel would not be used, it just wouldn't have the strength.

Just move your finger.

I wouldn’t worry about it breaking, but it may not be able to be aligned to specs unless you happened to get it straightened just right.

After all that money saving took place I wonder what you would do when it broke on you at 70 MPH?

 

[RAR]

Get a new or good salvage part.

If it bent and got bent back, now it’s got a potential failure point. You won’t want to trust that going forward.

 

[MSCH]

lets put it this way, you can unbend it, but its probably won't be worth a $### afterwards.

That is scrap metal now, replace it.
